I solve this problem (java can't find the jar).. If someone have the same problem the solution is: - download the xml-rpc 3.0 API (file: xmlrpc-current-bin.tar.gz); - extract and put the jar files on dir ;~/workspace//WEB-INF/lib/ - import the jars to the eclipse project in add external jars and check all the jars in order and export tab; - go to eclipse resource view, browse WEB-INF/lib and, clik and select to refresh with right button. I hope it could be usefull View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4176651#...
