Add a Apache-XMLRrpc-3.1.3 to a log listener

Apache XML-RPC is a Java language for XML-RPC protocol encapsulation. The XML-RPC protocol transmits XML fragments over HTTP to implement remote method calls.

In the use of apache-xmlrpc-3.1.3 as the XML-RPC client can not view the message interaction code stream in the log, only through the packet capture tool packet analysis, so modified the Apache-XMLRPC source code, to display interactive XML code streams through logs.

Add listener:

Package Org. apache. XMLRPC;/*** XMLRPC message listener ** @ author administrator <br/> * @ version <br/> * @ Email: zcg@suntektech.com <br/> * @ datetime: 2012-8-28 <br/> */public interface xmlrpcmessagelistener {/*** callback, XML string content that includes client requests and server responses ** @ Param xmlcontent */void onmessage (string xmlcontent );}

Client modification:
