## org.springframework.remoting.caucho
Class BurlapClientInterceptor

    java.lang.Object
      org.springframework.remoting.support.RemotingSupport
          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`.

Constructor Detail

### BurlapClientInterceptor

    public BurlapClientInterceptor()

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
