    JBOSS 7.1.1 Remote EJB Session is closed

      I have swing client which uses remote ejbs. The application starts correctly and it lookups remote ejbs successfully. However, after a few minutes, when an ejb is called, it gives an error like below. When we start the jboss again, we don't get the error and everything works. I couldn't understand the error below:

          One thing i forgot, i use standalone.xml that comes with default jboss 7.1.1 distribution. I think the error at the post is related with messaging. However, there is no jms messaging configuration in standalone.xml.

            When we start the jboss again, we don't get the error and everything works. I couldn't understand the error below:

            So does that mean the server goes down for a period of time and that's when you see these messages? That would make sense.

              Sorry, i don't mean that. JBOSS is alive. Some time later somehow client couldn't call ejb metods from alive JBOSS. The exception was thrown in client log. After we restart the jboss, everything works.

                  Just to help others...

                   

                  See

                  Scoped EJB client contexts - WildFly 8 - Project Documentation Editor

                  Somehow you need to close the opened context (generally ejb root context).

                  Be careful with CDI and pre-destroy.

                   

                  If you don't want to close it, try this:

                    I had seen such exceptions in my application when java had crashed.

                    Check /var/log/messages if java had crashed... Java in my application had crashed because of "Out of memory" issues.
