    ClassCastException: SingleOption cannot be cast to Option when accessing initial context from JBoss to JBoss

    Sebastian Bayerlein Newbie

      Hello,

       

      I deployed 2 EAR's on one JBoss instance. The ejb's are included in A.ear. A class of B.ear is calling an ejb of A.ear.

       

      To access the initial context (from B.ear), I use the following code:

       

      InitialContext result = null;

      Properties h = new Properties();

      h.put(Context.INITIAL_CONTEXT_FACTORY, serverCtxFactory);

      h.put(Context.PROVIDER_URL, "remote://10.2.5.81:10106");

      h.put(Context.SECURITY_PRINCIPAL, appServerUser);

      h.put(Context.SECURITY_CREDENTIALS, appServerPassword);

       

      h.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

      h.put("jboss.naming.client.ejb.context", true);

      h.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");

      h.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");

      h.put("remote.connection.default.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS", "JBOSS-LOCAL-USER");

       

      Properties pr = new Properties();

      pr.put("endpoint.name", "client-endpoint");

      pr.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");

      pr.put("remote.connections", "default");

      pr.put("remote.connection.default.port", "10106");

      pr.put("remote.connection.default.host", "10.2.5.81");

      pr.put("remote.connection.default.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS", "JBOSS-LOCAL-USER");

      pr.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");

      pr.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");

      pr.put("remote.connection.default.username", appServerUser);

      pr.put("remote.connection.default.password", appServerPassword);

       

      EJBClientConfiguration cc = new PropertiesBasedEJBClientConfiguration(pr);

      ContextSelector<EJBClientContext> selector = new ConfigBasedEJBClientContextSelector(cc);

      EJBClientContext.setSelector(selector);

       

      result = new InitialContext(h);

       

      This works, when accessing an ejb from a remote client, like a tomcat.

      But when access the ejb on the same JBoss instance, I get the following error:

       

      07:55:11,452 INFO  [stdout] (Thread-71) java.lang.ClassCastException: org.xnio.SingleOption cannot be cast to org.xnio.Option

      Has someone a solution for this problem?

          In the same JBoss instance you use call-by-reference, remote it is call-by-value because of the selialization.

           

          You have two options, set the call-by-value for local calls, but I don't recommend this because of the performance.

           

          Second is to check how you package the application, I suppose that you include the org.xnio libraries in the deployed archives.

          In this case it will be loaded by different classloaders that cause this error.

            Sebastian Bayerlein Newbie

            I included jboss-client.jar in B.ear. In A.ear, there are no JBoss libs included.

            Remove jboss-client.jar from B.ear causes the following warnings and exceptions.

             

            How must B.ear be configured to find the class org.xnio.Options?

              OK, I added the following to the jboss-deployment-structure.xml of B.ear:

               

                <sub-deployment name="[application].war">

                  <exclusions><module name="org.apache.log4j" /></exclusions>

                </sub-deployment>

               

              The error Class 'org.xnio.Options' not found no longer occurs. Now this is the problem:

                There are only INFO messages. The WARN can be ignored it will be no longer a WARN message in further versions.

                 

                But what about your application? Does it work?

                  Sebastian Bayerlein Newbie

                  The error is logged as INFO, that is a problem of the application I think. The application catches the throwable.

                  What you see in the stacktrace is the error which occured when setSelector is executed.

                   

                  The application doesn't work.

                    Thanks. This article describes the configuration, if A.ear and B.ear are on different JBoss instances.

                    Can I also use this configuration if A.ear and B.ear are on the same instance?

                      I changed the "client"-code to:

                       

                      InitialContext result = null;

                      Properties h = new Properties();

                       

                      h.put("java.naming.security.principal", appServerUser);

                      h.put("java.naming.security.credentials", appServerPassword);

                      h.put("java.naming.factory.url.pkgs", "org.jboss.ejb.client.naming");

                       

                      result = new InitialContext(h);

                       

                      jboss-deployment-strucuture.xml has the following dependencies:
