Description copied from class: AbstractHttpInvokerRequestExecutor

Execute a request to send the given serialized remote invocation.

Implementations will usually call readRemoteInvocationResult to deserialize a returned RemoteInvocationResult object.

Specified by:

doExecuteRequest in class AbstractHttpInvokerRequestExecutor

Parameters:

config - the HTTP invoker configuration that specifies the target service

baos - the ByteArrayOutputStream that contains the serialized RemoteInvocation object

Returns:

the RemoteInvocationResult object

Throws:

ClassNotFoundException - if thrown during deserialization

IOException - if thrown by I/O operations

AbstractHttpInvokerRequestExecutor.readRemoteInvocationResult(java.io.InputStream, String)

createPostMethod

protected PostMethod createPostMethod(HttpInvokerClientConfiguration config)
                               throws IOException

Create a PostMethod for the given configuration.

Parameters:

config - the HTTP invoker configuration that specifies the target service

Returns:

the PostMethod instance

Throws:

IOException - if thrown by I/O methods

executePostMethod

protected void executePostMethod(HttpInvokerClientConfiguration config,
                                 HttpClient httpClient,
                                 PostMethod postMethod)
                          throws IOException

Execute the given PostMethod instance.

Parameters:

config - the HTTP invoker configuration that specifies the target service
