Conclusions:

Axis2 provides ServiceClient class to represent an XML document based Web service client.
The Chunked HTTP flag must be turned to avoid the "Transport error: 411 Error: Length Required" error.
The sendReceive() method can be used to invoke an XML document based operation.
Input and output XML documents can be represented as OMElement objects.
Axis2 provides RPCServiceClient class to represent an RPC method based Web service client.
The invokeBlocking() method can be used to invoke an RPC method based operation.
