Hi Peter, now the problem is more restricted. Only the requests sent from a client that is on the same machine of the JBOSS AppServer are duplicated (so calls to localhost). If the client and the server are on different machines (or the client invokes the server by its http://ipaddress:port/url instead of http://localhost:8080/url) the problem does not exists. So I think that, as you suppose, the problem could be related to some network issues. Tnx! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977450#...
