I did some more investigation in the meantime. The exception with the JBoss Remoting 2.2.0 version was caused by the fact that it tried to access a trust store that was not existing. Through the parameter org.jboss.remoting.serverAuthMode one should be able to set from the outside that server certs are not validated. However I could so far not achieve that, neither through -D... nor through the config. So I changed the library code. It is working now, even so I'm not sure that my changes for the issue 1141 are absolutely correct. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037572#...
