org.springframework.web.jsf

Class WebApplicationContextVariableResolver

java.lang.Object

javax.faces.el.VariableResolver

org.springframework.web.jsf.WebApplicationContextVariableResolver

Deprecated.

as of Spring 3.2, in favor of the JSF 1.2 based WebApplicationContextFacesELResolver

@Deprecated
public class WebApplicationContextVariableResolver
extends VariableResolver

Special JSF 1.1 VariableResolver that exposes the Spring WebApplicationContext instance under a variable named "webApplicationContext".

In contrast to DelegatingVariableResolver, this VariableResolver does not resolve JSF variable names as Spring bean names. It rather exposes Spring's root WebApplicationContext itself under a special name. JSF-managed beans can then use Spring's WebApplicationContext API to retrieve Spring-managed beans, access resources, etc.

Configure this resolver in your faces-config.xml file as follows:

 <application>
   ...
   <variable-resolver>org.springframework.web.jsf.WebApplicationContextVariableResolver</variable-resolver>
 </application>

Since:

1.2.5

Constructor Detail

WebApplicationContextVariableResolver

public WebApplicationContextVariableResolver(VariableResolver originalVariableResolver)

Deprecated.

Create a new WebApplicationContextVariableResolver, using the given original VariableResolver.

A JSF implementation will automatically pass its original resolver into the constructor of a configured resolver, provided that there is a corresponding constructor argument.

Parameters:

originalVariableResolver - the original VariableResolver

Method Detail

getOriginalVariableResolver

protected final VariableResolver getOriginalVariableResolver()

Deprecated.

Return the original JSF VariableResolver that this resolver delegates to. Used to resolve standard JSF-managed beans.

resolveVariable

public Object resolveVariable(FacesContext context,
                     String name)
                       throws EvaluationException

Deprecated.

Check for the special "webApplicationContext" variable first, then delegate to the original VariableResolver.

If no WebApplicationContext is available, all requests will be delegated to the original VariableResolver.

Specified by:

resolveVariable in class VariableResolver

Throws:

EvaluationException

getWebApplicationContext

protected WebApplicationContext getWebApplicationContext(FacesContext facesContext)

Deprecated.

Retrieve the WebApplicationContext reference to expose.

The default implementation delegates to FacesContextUtils, returning null if no WebApplicationContext found.

Parameters:

facesContext - the current JSF context

Returns:

the Spring web application context
