    Remote EJB calls

    Michael Hansen Newbie

      I am currently in the process of upgrading a WF 13 -> WF 16 and Java 8 -> Java 11.

       

      We have an environment with several WF servers talking remotely to each other using Apache CXF web services. When trying to upgrade to Java 11/WF16 that stopped working, as the WF version is <3.3.

       

      I am now trying to rewrite our connection to use JNDI instead for remote calls, and that is working fine if I only calls remotely on a single server, but the moment I try to call EJB's on other WF servers I gets an error

      (classnames, servers passwords changed):

       

      Client:

           private void testRemoteCall() {

                  Object remote = connectRemote("TestEJB", "test", TestRemote.class.getName());

                  if (remote != null) {

                      TestRemote testEJB = (TestRemote) remote;

                      String output =  testEJB.getDate("input");

                      logger.info("Found: " + output);

                  } else {

                      logger.error("Could not find remote interface");

                  }

          }

       

          private Object connectRemote(String beanName, String appName, String viewClassName) {

              try {

                  final Hashtable jndiProperties = new Hashtable();

                  jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");

                  final Context context = new InitialContext(jndiProperties);

                  final String moduleName = appName + "-ejb-impl";

                  final String distinctName = "";

                  String lookupUrl = "ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName;

                  logger.info(lookupUrl);

                  return context.lookup(lookupUrl);

              } catch (Exception e) {

                  logger.error("Lookup error", e);

              }

              return null;

          }

       

      Error:

      Any idea of what I am doing wrong or missing?
