      org.springframework.remoting.support.RemoteAccessor
          org.springframework.remoting.support.UrlBasedRemoteAccessor
              org.springframework.remoting.caucho.BurlapClientInterceptor

All Implemented Interfaces:

Advice, Interceptor, MethodInterceptor, BeanClassLoaderAware, InitializingBean

Direct Known Subclasses:

BurlapProxyFactoryBean

public class BurlapClientInterceptor
extends UrlBasedRemoteAccessor
implements MethodInterceptor

MethodInterceptor for accessing a Burlap service. Supports authentication via username and password. The service URL must be an HTTP URL exposing a Burlap service.

Burlap is a slim, XML-based RPC protocol. For information on Burlap, see the Burlap website

Note: There is no requirement for services accessed with this proxy factory to have been exported using Spring's BurlapServiceExporter, as there is no special handling involved. As a consequence, you can also access services that have been exported using Caucho's BurlapServlet.

Method Detail

setProxyFactory

public void setProxyFactory(com.caucho.burlap.client.BurlapProxyFactory proxyFactory)

Set the BurlapProxyFactory instance to use. If not specified, a default BurlapProxyFactory will be created.

Allows to use an externally configured factory instance, in particular a custom BurlapProxyFactory subclass.

setUsername

public void setUsername(String username)

Set the username that this factory should use to access the remote service. Default is none.

The username will be sent by Burlap via HTTP Basic Authentication.

See Also:

BurlapProxyFactory.setUser(java.lang.String)

setPassword

public void setPassword(String password)

Set the password that this factory should use to access the remote service. Default is none.

The password will be sent by Burlap via HTTP Basic Authentication.

See Also:

BurlapProxyFactory.setPassword(java.lang.String)

setOverloadEnabled

public void setOverloadEnabled(boolean overloadEnabled)

Set whether overloaded methods should be enabled for remote invocations. Default is "false".

See Also:

BurlapProxyFactory.setOverloadEnabled(boolean)

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

Overrides:

afterPropertiesSet in class UrlBasedRemoteAccessor

prepare

public void prepare()
             throws RemoteLookupFailureException

Initialize the Burlap proxy for this interceptor.

Throws:

RemoteLookupFailureException - if the service URL is invalid

createBurlapProxy

protected Object createBurlapProxy(com.caucho.burlap.client.BurlapProxyFactory proxyFactory)
                            throws MalformedURLException

Create the Burlap proxy that is wrapped by this interceptor.

Parameters:

proxyFactory - the proxy factory to use

Returns:

the Burlap proxy

Throws:

MalformedURLException - if thrown by the proxy factory

See Also:

BurlapProxyFactory.create(java.lang.String)

invoke

public Object invoke(MethodInvocation invocation)
              throws Throwable

Specified by:

invoke in interface MethodInterceptor

Throws:

Throwable

convertBurlapAccessException

protected RemoteAccessException convertBurlapAccessException(Throwable ex)

Convert the given Burlap access exception to an appropriate Spring RemoteAccessException.

Parameters:

ex - the exception to convert

Returns:

the RemoteAccessException to throw
