Direct Known Subclasses:

public class HttpInvokerClientInterceptor

extends RemoteInvocationBasedAccessor

implements org.aopalliance.intercept.MethodInterceptor, HttpInvokerClientConfiguration

Interceptor for accessing an HTTP invoker service. The service URL must be an HTTP URL exposing an HTTP invoker service.

Simply serializes remote invocation objects and deserializes remote invocation results. Uses Java serialization just like RMI, but provides the same ease of setup as Caucho's HTTP-based Hessian and Burlap protocols.

1.1

executeRequest

protected RemoteInvocationResult executeRequest(RemoteInvocation invocation)
                                         throws java.io.IOException,
                                                java.lang.ClassNotFoundException

Execute the given remote invocation via the HttpInvokerRequestExecutor.

Can be overridden in subclasses to pass a different configuration object to the executor. Alternatively, add further configuration properties in a subclass of this accessor: By default, the accessor passed itself as configuration object to the executor.

Parameters:

invocation - the RemoteInvocation to execute

Returns:

the RemoteInvocationResult object

Throws:

java.io.IOException - if thrown by I/O operations

java.lang.ClassNotFoundException - if thrown during deserialization

getHttpInvokerRequestExecutor(), HttpInvokerClientConfiguration

recreateRemoteInvocationResult

protected java.lang.Object recreateRemoteInvocationResult(RemoteInvocationResult result)
                                                   throws java.lang.Throwable

Recreate the invocation result contained in the given RemoteInvocationResult object. The default implementation calls the default recreate method.

Can be overridden in subclass to provide custom recreation, potentially processing the returned result object.

Parameters:

result - the RemoteInvocationResult to recreate

Returns:

a return value if the invocation result is a successful return

Throws:

java.lang.Throwable - if the invocation result is an exception
