    problem calling a remote ejb from a servlet in a cluster env

    de vito gabriele Newbie

      I've three jboss instances on different machine in the same network:
      1. Jboss (A) running a web application
      2. Jboss (B) running some ejbs
      3. Jboss (C) running some ejbs


      Jboss (B) and Jboss (C) are in the same partition.

      In a servlet, running in the first jboss intance (A), I call an ejb
      deployed in the cluster (B,C) using autodiscovery (using jnp.port,
      jnp.partitionName etc..).

      You suppose the Jboss C responds to this call (made from servlet).

      If the server C goes down the next call to this ejb throws this error :

      java.rmi.ConnectException: Connection refused to host: serverC; nested exception is:
      java.net.ConnectException: Connection refused
