    Remote EJB calls ?

    Kumar Jaya Newbie

      I am using JBOSS 4.2.2 and EJB 3.0. I am accessing an EJB remotely from a client. I wanted to make a test run and made my calls within a while loop

      Ex:

      while (true) {
      // Call Remote Bean
      }

      It run well for some time and then it gave the following exception

      ex=Can not get connection to server. Problem establishing socket connection for InvokerLocator [socket://x.x.x.x:3873/]
      org.jboss.remoting.CannotConnectException: Can not get connection to server. Problem establishing socket connection for InvokerLocator [socket://x.x.x.x:3873/]

      Is there any way to configure the number of connections in the pool? Or whether there is any limitation on the number of calls to the EJB within a specified time limit?
