    Adding a dependency on HornetQ RAR deployment

    Tomohisa igarashi Master

      Hi,

       

      Could anybody let me know how can I wait for HornetQ RAR deployment on AS7?

       

      Our SwitchYard JCA integration acquires the ResourceAdapter instance from ResourceAdapterRepository, so the RAR should have been deployed before the SwitchYard JCA application. Adding a dependency on RAR deployment with jboss-deployment-structure.xml should work in most cases. However, it didn't work for HornetQ even if I added a dependency on deployment.hornetq-ra. Is there any way to depend on HornetQ RAR deployment on AS7?

       

      Thanks,

      Tomo

          Try setting your dependency on "jboss.ra.hornetq-ra" and let me know if that works.

            Thanks for the idea Justin, but no luck... apparently it's looking for the module.

            "deployment." prefix is obviously working as a magic word, but just doesn't work for HornetQ built-in RAR.

              Anyone has any idea? Sounds like the only way to do this is adding subsystem dependency in the code... I'd really like to avoid it if I can....

                I fixed via dumb way:


                1. Made a web-application with ServletContextListener which tries to lookup for java:/JmsXA in a loop until it is available (actually after HornetQ startup)

                2. Add a jboss-all.xml dependencies to all other deployments so they depend on my webapp deployment

                3. Profit!!!111


                Could not attach files, so the sources inlined:

                 

                @WebListener
                public class StartupListener implements ServletContextListener {
                
                
                  private static final Logger LOGGER = LoggerFactory
                  .getLogger(StartupListener.class);
                
                
                  public void contextInitialized(ServletContextEvent event) {
                  InitialContext ctx;
                  try {
                  ctx = new InitialContext();
                  } catch (Throwable t) {
                  throw new RuntimeException(t);
                  }
                  Object jmsXA = null;
                  while (true) {
                  try {
                  jmsXA = ctx.lookup("java:/JmsXA");
                  if (jmsXA != null) {
                  LOGGER.info("JmsXA found to be started");
                  break;
                  }
                  Thread.sleep(1000);
                  } catch (Exception e) {
                  LOGGER.info("Waiting for JmsXA to start...");
                  LOGGER.trace("Exception looking up JmsXA", e);
                  try {
                  Thread.sleep(1000);
                  } catch (InterruptedException e1) {
                  LOGGER.warn("Interrupted waiting for JmsXA to start");
                  }
                  }
                  }
                  }
                
                
                  public void contextDestroyed(ServletContextEvent event) {
                  // nothing
                  }
                }

                  Just FYI - Since I couldn't find any way to do this except polling, decided to let the AS7 deployment processor handle it.

                  [SWITCHYARD-1789] JCAActivator should wait for the HornetQ RAR deployment - JBoss Issue Tracker

                   

                  Now SwitchYard JCA gateway always waits for the RAR initialization including HornetQ built-in RAR. You don't have to do anything after SwitchYard 1.1.
