Chapter 15. Integrating with other web frameworks

15.1. Introduction

This chapter details Spring's integration with third party web frameworks such as Struts, JSF, Tapestry, and WebWork.

One of the core value propositions of the Spring Framework is that of enabling choice. In a general sense, Spring does not force one to use or buy into any particular architecture, technology, or methodology (although it certainly recommends some over others). This freedom to pick and choose the architecture, technology, or methodology that is most relevant to a developer and his or her development team is arguably most evident in the web area, where Spring provides its own web framework (SpringMVC), while at the same time providing integration with a number of popular third party web frameworks. This allows one to continue to leverage any and all of the skills one may have acquired in a particular web framework such as Struts, while at the same time being able to enjoy the benefits afforded by Spring in other areas such as data access, declarative transaction management, and flexible configuration and application assembly.

Having dispensed with the woolly sales patter (c.f. the previous paragraph), the remainder of this chapter will concentrate upon the meaty details of integrating your favourite web framework with Spring. One thing that is often commented upon by developers coming to Java from other languages is the seeming super-abundance of web frameworks available in Java... there are indeed a great number of web frameworks in the Java space; in fact there are far too many to cover with any semblance of detail in a single chapter. This chapter thus picks four of the more popular web frameworks in Java, starting with the Spring configuration that is common to all of the supported web frameworks, and then detailing the specific integration options for each supported web framework.

Please note that this chapter does not attempt to explain how to use any of the supported web frameworks. For example, if you want to use Struts for the presentation layer of your web application, the assumption is that you are already familiar with Struts. If you need further details about any of the supported web frameworks themselves, please do consult the section entitled Section 15.7, “Further Resources” at the end of this chapter.

15.2. Common configuration

Before diving into the integration specifics of each supported web framework, let us first take a look at the Spring configuration that not specific to any one web framework. (This section is equally applicable to Spring's own web framework, SpringMVC.)

One of the concepts (for want of a better word) espoused by (Spring's) lightweight application model is that of a layered architecture. Remember that in a 'classic' layered architecture, the web layer is but one of many layers... it serves as one of the entry points into a server side application, and it delegates to service objects (facades) defined in a service layer to satisfy business specific (and presentation-technology agnostic) use cases. In Spring, these service objects, any other business-specific objects, data access objects, etc. exist in a distinct 'business context', which contains no web or presentation layer objects (presentation objects such as Spring MVC controllers are typically configured in a distinct 'presentation context'). This section details how one configures a Spring container (a WebApplicationContext) that contains all of the 'business beans' in one's application.

Onto specifics... all that one need do is to declare a ContextLoaderListener in the standard J2EE servlet web.xml file of one's web application, and add a contextConfigLocation <context-param/> section (in the same file) that defines which set of Spring XML cpnfiguration files to load.

Find below the <listener/> configuration:


Listeners were added to the Servlet API in version 2.3. If you have a Servlet 2.2 container, you can use the ContextLoaderServlet to achieve this same functionality.

Find below the <context-param/> configuration:


If you don't specify the contextConfigLocation context parameter, the ContextLoaderListener will look for a file called /WEB-INF/applicationContext.xml to load. Once the context files are loaded, Spring creates a WebApplicationContext object based on the bean definitions and stores it in the ServletContext of one's web application.

All Java web frameworks are built on top of the Servlet API, and so one can use the following code snippet to get access to this 'business context' ApplicationContext created by the ContextLoaderListener.

WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext);

The WebApplicationContextUtils class is for convenience, so you don't have to remember the name of the ServletContext attribute. Its getWebApplicationContext() method will return null if an object doesn't exist under the WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE key. Rather than risk getting NullPointerExceptions in your application, it's better to use the getRequiredWebApplicationContext() method. This method throws an exception when the ApplicationContext is missing.

Once you have a reference to the WebApplicationContext, you can retrieve beans by their name or type. Most developers retrieve beans by name, then cast them to one of their implemented interfaces.

Fortunately, most of the frameworks in this section have simpler ways of looking up beans. Not only do they make it easy to get beans from a Spring container, but they also allow you to use dependency injection on their controllers. Each web framework section has more detail on its specific integration strategies.

15.3. JavaServer Faces

JavaServer Faces (JSF) is an increasingly popular component-based, event-driven web framework. The key class in Spring's JSF integration is the DelegatingVariableResolver class.

15.3.1. DelegatingVariableResolver

The easiest way to integrate one's Spring middle-tier with one's JSF web layer is to use the DelegatingVariableResolver class. To configure this variable resolver in one's application, one will need to edit one's faces-context.xml file. After the opening <faces-config/> element, add an <application/> element and a <variable-resolver/> element within it. The value of the variable resolver should reference Spring's DelegatingVariableResolver; for example:


The DelegatingVariableResolver will first delegate value lookups to the default resolver of the underlying JSF implementation, and then to Spring's 'business context' WebApplicationContext. This allows one to easily inject dependencies into one's JSF-managed beans.

Managed beans are defined in one's faces-config.xml file. Find below an example where #{userManager} is a bean that is retrieved from the Spring 'business context'.


15.3.2. FacesContextUtils

A custom VariableResolver works well when mapping one's properties to beans in faces-config.xml, but at times one may need to grab a bean explicitly. The FacesContextUtils class makes this easy. It is similar to WebApplicationContextUtils, except that it takes a FacesContext parameter rather than a ServletContext parameter.

ApplicationContext ctx = FacesContextUtils.getWebApplicationContext(FacesContext.getCurrentInstance());

The DelegatingVariableResolver is the recommended strategy for integrating JSF and Spring. If one is looking for more robust integration features, one might want take a look at the JSF-Spring project.

15.4. Struts

Struts is the de facto web framework for Java applications, mainly because it was one of the first to be released (June 2001). Invented by Craig McClanahan, Struts is an open source project hosted by the Apache Software Foundation. At the time, it greatly simplified the JSP/Servlet programming paradigm and won over many developers who were using proprietary frameworks. It simplified the programming model, it was open source (and thus free as in beer), and it had a large community, which allowed the project to grow and become popular among Java web developers.

To integrate your Struts application with Spring, you have two options:

  • Configure Spring to manage your Actions as beans, using the ContextLoaderPlugin, and set their dependencies in a Spring context file.

  • Subclass Spring's ActionSupport classes and grab your Spring-managed beans explicitly using a getWebApplicationContext() method.

15.4.1. ContextLoaderPlugin

The ContextLoaderPlugin is a Struts 1.1+ plug-in that loads a Spring context file for the Struts ActionServlet. This context refers to the root WebApplicationContext (loaded by the ContextLoaderListener) as its parent. The default name of the context file is the name of the mapped servlet, plus -servlet.xml. If ActionServlet is defined in web.xml as <servlet-name>action</servlet-name>, the default is /WEB-INF/action-servlet.xml.

To configure this plug-in, add the following XML to the plug-ins section near the bottom of your struts-config.xml file:

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn"/>

The location of the context configuration files can be customized using the 'contextConfigLocation' property.

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
  <set-property property="contextConfigLocation"

It is possible to use this plugin to load all your context files, which can be useful when using testing tools like StrutsTestCase. StrutsTestCase's MockStrutsTestCase won't initialize Listeners on startup so putting all your context files in the plugin is a workaround. (A bug has been filed for this issue, but has been closed as 'Wont Fix').

After configuring this plug-in in struts-config.xml, you can configure your Action to be managed by Spring. Spring (1.1.3+) provides two ways to do this:

  • Override Struts' default RequestProcessor with Spring's DelegatingRequestProcessor.

  • Use the DelegatingActionProxy class in the type attribute of your <action-mapping>.

Both of these methods allow you to manage your Actions and their dependencies in the action-servlet.xml file. The bridge between the Action in struts-config.xml and action-servlet.xml is built with the action-mapping's "path" and the bean's "name". If you have the following in your struts-config.xml file:

<action path="/users" .../>

You must define that Action's bean with the "/users" name in action-servlet.xml:

<bean name="/users" .../> DelegatingRequestProcessor

To configure the DelegatingRequestProcessor in your struts-config.xml file, override the "processorClass" property in the <controller> element. These lines follow the <action-mapping> element.

  <set-property property="processorClass"

After adding this setting, your Action will automatically be looked up in Spring's context file, no matter what the type. In fact, you don't even need to specify a type. Both of the following snippets will work:

<action path="/user" type="com.whatever.struts.UserAction"/>		
<action path="/user"/>

If you're using Struts' modules feature, your bean names must contain the module prefix. For example, an action defined as <action path="/user"/> with module prefix "admin" requires a bean name with <bean name="/admin/user"/>.


If you are using Tiles in your Struts application, you must configure your <controller> with the DelegatingTilesRequestProcessor instead. DelegatingActionProxy

If you have a custom RequestProcessor and can't use the DelegatingRequestProcessor or DelegatingTilesRequestProcessor approaches, you can use the DelegatingActionProxy as the type in your action-mapping.

<action path="/user" type="org.springframework.web.struts.DelegatingActionProxy"
    name="userForm" scope="request" validate="false" parameter="method">
  <forward name="list" path="/userList.jsp"/>
  <forward name="edit" path="/userForm.jsp"/>

The bean definition in action-servlet.xml remains the same, whether you use a custom RequestProcessor or the DelegatingActionProxy.

If you define your Action in a context file, the full feature set of Spring's bean container will be available for it: dependency injection as well as the option to instantiate a new Action instance for each request. To activate the latter, add scope="prototype" to your Action's bean definition.

<bean name="/user" scope="prototype" autowire="byName"

15.4.2. ActionSupport Classes

As previously mentioned, you can retrieve the WebApplicationContext from the ServletContext using the WebApplicationContextUtils class. An easier way is to extend Spring's Action classes for Struts. For example, instead of subclassing Struts' Action class, you can subclass Spring's ActionSupport class.

The ActionSupport class provides additional convenience methods, like getWebApplicationContext(). Below is an example of how you might use this in an Action:

public class UserAction extends DispatchActionSupport {

    public ActionForward execute(ActionMapping mapping,
                                 ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) throws Exception {
        if (log.isDebugEnabled()) {
            log.debug("entering 'delete' method...");
        WebApplicationContext ctx = getWebApplicationContext();
        UserManager mgr = (UserManager) ctx.getBean("userManager");
        // talk to manager for business logic
        return mapping.findForward("success");

Spring includes subclasses for all of the standard Struts Actions - the Spring versions merely have Support appended to the name:

The recommended strategy is to use the approach that best suits your project. Subclassing makes your code more readable, and you know exactly how your dependencies are resolved. However, using the ContextLoaderPlugin allow you to easily add new dependencies in your context XML file. Either way, Spring provides some nice options for integrating the two frameworks.

15.5. Tapestry

From the Tapestry homepage...

Tapestry is an open-source framework for creating dynamic, robust, highly scalable web applications in Java. Tapestry complements and builds upon the standard Java Servlet API, and so it works in any servlet container or application server.

While Spring has its own powerful web layer, there are a number of unique advantages to building a J2EE application using a combination of Tapestry for the web user interface and the Spring container for the lower layers. This section of the web integration chapter attempts to detail a few best practices for combining these two frameworks.

A typical layered J2EE application built with Tapestry and Spring will consist of a top user interface (UI) layer built with Tapestry, and a number of lower layers, all wired together by one or more Spring containers. Tapestry's own reference documentation contains the following snippet of best practice advice. (Text that I the author have added is contained within [] brackets.)

A very succesful design pattern in Tapestry is to keep pages and components very simple, and delegate as much logic as possible out to HiveMind [or Spring, or whatever] services. Listener methods should ideally do little more than marshall together the correct information and pass it over to a service.

The key question then is... how does one supply Tapestry pages with collaborating services? The answer, ideally, is that one would want to dependency inject those services directly into one's Tapestry pages. In Tapestry, one can effect this dependency injection by a variety of means... this section is only going to enumerate the dependency injection means afforded by Spring. The real beauty of the rest of this Spring-Tapestry integration is that the elegant and flexible design of Tapestry itself makes doing this dependency injection of Spring-managed beans a cinch. (Another nice thing is that this Spring-Tapestry itegration code was written - and continues to be maintained - by the Tapestry creator Howard M. Lewis Ship, so hats off to him for what is really some silky smooth integration).

15.5.1. Injecting Spring-managed beans

Assume we have the following simple Spring container definition (in the ubiquitous XML format):

<?xml version="1.0" encoding="UTF-8"?>
    <!-- the DataSource -->
    <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="java:DefaultDS"/>

    <bean id="hibSessionFactory" 
        <property name="dataSource" ref="dataSource"/>

    <bean id="transactionManager" 

    <bean id="mapper" 
        <property name="sessionFactory" ref="hibSessionFactory"/>

    <!-- (transactional) AuthenticationService -->
    <bean id="authenticationService" 
        <property name="transactionManager" ref="transactionManager"/>
        <property name="target">
            <bean class="">
                <property name="mapper" ref="mapper"/>
        <property name="proxyInterfacesOnly" value="true"/>
        <property name="transactionAttributes">
    <!-- (transactional) UserService -->
    <bean id="userService" 
        <property name="transactionManager" ref="transactionManager"/>
        <property name="target">
             <bean class="">
                 <property name="mapper" ref="mapper"/>
        <property name="proxyInterfacesOnly" value="true"/>
        <property name="transactionAttributes">

Inside the Tapestry application, the above bean definitions need to be loaded into a Spring container, and any relevant Tapestry pages need to be supplied (injected) with the authenticationService and userService beans, which implement the AuthenticationService and UserService interfaces, respectively.

At this point, the application context is available to a web application by calling Spring's static utility function WebApplicationContextUtils.getApplicationContext(servletContext), where servletContext is the standard ServletContext from the J2EE Servlet specification. As such, one simple mechanism for a page to get an instance of the UserService, for example, would be with code such as:

WebApplicationContext appContext = WebApplicationContextUtils.getApplicationContext(
UserService userService = (UserService) appContext.getBean("userService");
... some code which uses UserService

This mechanism does work... having said that, it can be made a lot less verbose by encapsulating most of the functionality in a method in the base class for the page or component. However, in some respects it goes against the IoC principle; ideally you would like the page to not have to ask the context for a specific bean by name, and in fact, the page would ideally not know about the context at all.

Luckily, there is a mechanism to allow this. We rely upon the fact that Tapestry already has a mechanism to declaratively add properties to a page, and it is in fact the preferred approach to manage all properties on a page in this declarative fashion, so that Tapestry can properly manage their lifecycle as part of the page and component lifecycle.


This next section is applicable to versions of Tapestry < 4.0. if you are using Tapestry version 4.0+, please consult the section entitled Section, “Dependency Injecting Spring Beans into Tapestry pages - Tapestry 4.0+ style”. Dependency Injecting Spring Beans into Tapestry pages

First we need to make the ApplicationContext available to the Tapestry page or Component without having to have the ServletContext; this is because at the stage in the page's/component's lifecycle when we need to access the ApplicationContext, the ServletContext won't be easily available to the page, so we can't use WebApplicationContextUtils.getApplicationContext(servletContext) directly. One way is by defining a custom version of the Tapestry IEngine which exposes this for us:

package com.whatever.web.xportal;

import ...

public class MyEngine extends org.apache.tapestry.engine.BaseEngine {
    public static final String APPLICATION_CONTEXT_KEY = "appContext";
     * @see org.apache.tapestry.engine.AbstractEngine#setupForRequest(org.apache.tapestry.request.RequestContext)
    protected void setupForRequest(RequestContext context) {
        // insert ApplicationContext in global, if not there
        Map global = (Map) getGlobal();
        ApplicationContext ac = (ApplicationContext) global.get(APPLICATION_CONTEXT_KEY);
        if (ac == null) {
            ac = WebApplicationContextUtils.getWebApplicationContext(
            global.put(APPLICATION_CONTEXT_KEY, ac);

This engine class places the Spring Application Context as an attribute called "appContext" in this Tapestry app's 'Global' object. Make sure to register the fact that this special IEngine instance should be used for this Tapestry application, with an entry in the Tapestry application definition file. For example:

file: xportal.application: 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE application PUBLIC 
    "-//Apache Software Foundation//Tapestry Specification 3.0//EN" 
    name="Whatever xPortal"
</application> Component definition files

Now in our page or component definition file (*.page or *.jwc), we simply add property-specification elements to grab the beans we need out of the ApplicationContext, and create page or component properties for them. For example:

    <property-specification name="userService"
    <property-specification name="authenticationService"

The OGNL expression inside the property-specification specifies the initial value for the property, as a bean obtained from the context. The entire page definition might look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE page-specification PUBLIC 
    "-//Apache Software Foundation//Tapestry Specification 3.0//EN" 
<page-specification class="com.whatever.web.xportal.pages.Login">
    <property-specification name="username" type="java.lang.String"/>
    <property-specification name="password" type="java.lang.String"/>
    <property-specification name="error" type="java.lang.String"/>
    <property-specification name="callback" type="org.apache.tapestry.callback.ICallback" persistent="yes"/>
    <property-specification name="userService"
    <property-specification name="authenticationService"
    <bean name="delegate" class="com.whatever.web.xportal.PortalValidationDelegate"/>
    <bean name="validator" class="org.apache.tapestry.valid.StringValidator" lifecycle="page">
        <set-property name="required" expression="true"/>
        <set-property name="clientScriptingEnabled" expression="true"/>
    <component id="inputUsername" type="ValidField">
        <static-binding name="displayName" value="Username"/>
        <binding name="value" expression="username"/>
        <binding name="validator" expression="beans.validator"/>
    <component id="inputPassword" type="ValidField">
        <binding name="value" expression="password"/>
       <binding name="validator" expression="beans.validator"/>
       <static-binding name="displayName" value="Password"/>
       <binding name="hidden" expression="true"/>
</page-specification> Adding abstract accessors

Now in the Java class definition for the page or component itself, all we need to do is add an abstract getter method for the properties we have defined (in order to be able to access the properties).

// our UserService implementation; will come from page definition
public abstract UserService getUserService();
// our AuthenticationService implementation; will come from page definition
public abstract AuthenticationService getAuthenticationService();

For the sake of completeness, the entire Java class, for a login page in this example, might look like this:

package com.whatever.web.xportal.pages;
 *  Allows the user to login, by providing username and password.
 *  After successfully logging in, a cookie is placed on the client browser
 *  that provides the default username for future logins (the cookie
 *  persists for a week).
public abstract class Login extends BasePage implements ErrorProperty, PageRenderListener {
    /** the key under which the authenticated user object is stored in the visit as */
    public static final String USER_KEY = "user";
    /** The name of the cookie that identifies a user **/
    private static final String COOKIE_NAME = Login.class.getName() + ".username";  
    private final static int ONE_WEEK = 7 * 24 * 60 * 60;
    public abstract String getUsername();
    public abstract void setUsername(String username);
    public abstract String getPassword();
    public abstract void setPassword(String password);
    public abstract ICallback getCallback();
    public abstract void setCallback(ICallback value);
    public abstract UserService getUserService();
    public abstract AuthenticationService getAuthenticationService();
    protected IValidationDelegate getValidationDelegate() {
        return (IValidationDelegate) getBeans().getBean("delegate");
    protected void setErrorField(String componentId, String message) {
        IFormComponent field = (IFormComponent) getComponent(componentId);
        IValidationDelegate delegate = getValidationDelegate();
        delegate.record(new ValidatorException(message));
     *  Attempts to login. 
     * <p>
     *  If the user name is not known, or the password is invalid, then an error
     *  message is displayed.
    public void attemptLogin(IRequestCycle cycle) {
        String password = getPassword();
        // Do a little extra work to clear out the password.
        IValidationDelegate delegate = getValidationDelegate();
        delegate.setFormComponent((IFormComponent) getComponent("inputPassword"));
        // An error, from a validation field, may already have occurred.
        if (delegate.getHasErrors()) {

        try {
            User user = getAuthenticationService().login(getUsername(), getPassword());
           loginUser(user, cycle);
        catch (FailedLoginException ex) {
            this.setError("Login failed: " + ex.getMessage());
     *  Sets up the [email protected] User} as the logged in user, creates
     *  a cookie for their username (for subsequent logins),
     *  and redirects to the appropriate page, or
     *  a specified page).
    public void loginUser(User user, IRequestCycle cycle) {
        String username = user.getUsername();
        // Get the visit object; this will likely force the
        // creation of the visit object and an HttpSession
        Map visit = (Map) getVisit();
        visit.put(USER_KEY, user);
        // After logging in, go to the MyLibrary page, unless otherwise specified
        ICallback callback = getCallback();
        if (callback == null) {
        else {

        IEngine engine = getEngine();
        Cookie cookie = new Cookie(COOKIE_NAME, username);
        // Record the user's username in a cookie
    public void pageBeginRender(PageEvent event) {
        if (getUsername() == null) {
} Dependency Injecting Spring Beans into Tapestry pages - Tapestry 4.0+ style

Effecting the dependency injection of Spring-managed beans into Tapestry pages in Tapestry version 4.0+ is so much simpler. All that is needed is a single add-on library, and some (small) amount of (essentially boilerplate) configuration. Simply package and deploy this library with the (any of the) other libraries required by your web application (typially in WEB-INF/lib).

You will then need to create and expose the Spring container using the method detailed previously. You can then inject Spring-managed beans into Tapestry very easily; if we are using Java 5, consider the Login page from above: we simply need to annotate the appropriate getter methods in order to dependency inject the Spring-managed userService and authenticationService objects (lots of the class definition has been elided for clarity)...

package com.whatever.web.xportal.pages;

public abstract class Login extends BasePage implements ErrorProperty, PageRenderListener {
    public abstract UserService getUserService();
    public abstract AuthenticationService getAuthenticationService();


We are almost done... all that remains is the HiveMind configuration that exposes the Spring container stored in the ServletContext as a HiveMind service; for example:

<?xml version="1.0"?>
<module id="com.javaforge.tapestry.spring" version="0.1.1">

    <service-point id="SpringApplicationInitializer"
            <construct class="com.javaforge.tapestry.spring.SpringApplicationInitializer">
                <set-object property="beanFactoryHolder"
                    value="service:hivemind.lib.DefaultSpringBeanFactoryHolder" />

    <!-- Hook the Spring setup into the overall application initialization. -->
        <command id="spring-context"
            object="service:SpringApplicationInitializer" />


If you are using Java 5 (and thus have access to annotations), then that really is it.

If you are not using Java 5, then one obviously doesn't annotate one's Tapestry page classes with annotations; instead, one simply uses good old fashioned XML to declare the dependency injection; for example, inside the .page or .jwc file for the Login page (or component):

<inject property="userService" object="spring:userService"/>
<inject property="authenticationService" object="spring:authenticationService"/>

In this example, we've managed to allow service beans defined in a Spring container to be provided to the Tapestry page in a declarative fashion. The page class does not know where the service implementations are coming from, and in fact it is easy to slip in another implementation, for example, during testing. This inversion of control is one of the prime goals and benefits of the Spring Framework, and we have managed to extend it all the way up the J2EE stack in this Tapestry application.

15.6. WebWork

From the WebWork homepage...

WebWork is a Java web-application development framework. It is built specifically with developer productivity and code simplicity in mind, providing robust support for building reusable UI templates, such as form controls, UI themes, internationalization, dynamic form parameter mapping to JavaBeans, robust client and server side validation, and much more.

WebWork is (in the opinion of this author) a very clean, elegant web framework. Its architecture and key concepts are not only very easy to understand, it has a rich tag library, nicely decoupled validation, and it is (again, in the opinion of this author) quite easy to be productive in next to no time at all (the documentation and tutorials are pretty good too).

One of the key enablers in WebWork's technology stack is an IoC container to manage Webwork Actions, handle the "wiring" of business objects, etc. Previous to WebWork version 2.2, WebWork used it's own proprietary IoC container (and provided integration points so that one could integrate an IoC container such as Springs into the mix). However, as of WebWork version 2.2, the default IoC container that is used within WebWork is Spring. This is obviously great news if one is a Spring developer, because it means that one is immediately familiar with the basics of IoC configuration, idioms and suchlike within WebWork.

Now in the interests of adhering to the DRY (Dont Repeat Yourself) principle, it would be foolish to writeup the Spring-WebWork integration in light of the fact that the WebWork team have already written such a writeup. Please do consult the Spring-WebWork integration page on the WebWork wiki for the full lowdown.

Note that the Spring-WebWork integration code was developed (and continues to be maintained and improved) by the WebWork developers themselves, so in the first instance please do refer to the WebWork site and forums if you are having issues with the integration. Do feel free to post comments and queries regarding the Spring-WebWork integration on the Spring support forums too.
