    Deployment error

    Rupert Young Newbie

      I am trying to deploy a simple project of just a socket listener, but get this deployment error

      ObjectName: jboss.esb:deployment=socket_server.esb
      State: FAILED
      Reason: java.lang.RuntimeException: org.jboss.soa.esb.ConfigurationException: Service configuration for Service 'MyServiceCategory:MySocketServer' doesn't define a Message-Aware Listener (i.e. is-gateway='false').

      even though is-gateway is set to true as can be seen below.

      Can anyone spot what I have got wrong?

          You need a non-gateway listener. The easy way to fix it is to enable the inVM listener on the service:

          <service .... invmScope="GLOBAL">

          or you can add a non-gateway listener -- see the webservice_producer quickstart for a socket example that uses a JMS ESB-aware (non-gateway) listener.

            Thanks.

            What I am trying to do is expose a socket server that an external system will connect to by tcpip and send a message, waiting for a reply. Don't I need a gateway for that?

            I am using webservice_producer as a template. Isn't the JMS ESB-aware (non-gateway) listener only visible internally (and not tcpip) ?

            Rupert

              Rupert,
              You need to configure both: a gateway listener to receive the message from the external client and an ESB-aware listener to transport the message within the bus. Look at the "Services and Messages" chapter in the Programmer's Guide if it's still not clear.

              Scott

                Scott,

                Ok, got a bit further. It seems to deploy successfully, a few things though,


                There are no endpoints deployed in http://localhost:8080/jbossws/services

                Testing with sendMessageToJBRListener sends a request and gets a response, but using an external tcpip test client I get this,

                at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:173)
                Caused by: java.io.StreamCorruptedException: invalid stream header: 68656C6C
                at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:783)

                is it expecting a particular envelope?

                Where does the request go in the esb? Is it onto a queue and to access the message I need to write a jmslisteneraction class?

                  That's OK. That page displays web services and you haven't deployed a web service.

                  I don't know why you get the StreamCorruptedException.

                  Where does the request go in the esb? Is it onto a queue and to access the message I need to write a jmslisteneraction class?

                  Your request is routed down the list of actions that you've specified. If you want to write some custom code to process the message, you can do that with your own action class. The helloworld quickstart has a good example of that. There are lots of other things you can do -- transform the message, route it to another service, etc.

                    Scott,

                    Thanks.

                    I don't know why you get the StreamCorruptedException.


                    Is there documentation somewhere which explains what the socket gateway is doing?
