XML-RPC in Xwiki.

Hi all, What's happen with xml-rpc in Xwiki? I have an application that access my pages using this URL http://panteao.xwiki.com/xwiki/bin/xmlrpc/confluence. In the past it's worked very well. Now, I have this problem Exception in thread "main" java.io.IOException: Server returned HTTP response code: 500 for URL: http://panteao.xwiki.com/xwiki/bin/xmlrpc/confluence Have had any changes? Best regards, Fabrício.
