In my case connection was established and several calls got through. The scenario is: 1. Connect to server 2. DoSomething1 3. DoSomething2 and disconnect in the same moment due to networking issue DoSomething2 fails with Exception being thrown. I export POJO with RMI transport and see the following stack. java.lang.reflect.UndeclaredThrowableException | at $Proxy244.stop(Unknown Source) | at ... | Caused by: java.lang.Exception: Can not make remoting client invocation due to not being connected to server. | at org.jboss.remoting.Client.invoke(Client.java:616) | at org.jboss.remoting.Client.invoke(Client.java:604) | at org.jboss.remoting.Client.invoke(Client.java:589) | at org.jboss.remoting.transporter.TransporterClient.invoke(TransporterClient.java:276) | at $Proxy244.stop(Unknown Source) at ... I didn't expect UndeclaredThrowableException in this situation. Thanks, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4058137#...
