    wildfly invok ejb error: EJBCLIENT000025

    长松 黄 Newbie

      Hi,

           I got the code in wildfly web.and deploy it to the server.

      09:57:28,871 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-7) JNDI bindings for session bean named CalculatorBean in deployment unit deployment "wildflyejb3.jar" are as follows:

          java:module/CounterBean
      

       

           Then I got  the  client code,and jboss-ejb-client.properties

      endpoint.name=client-endpoint
      remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

      remote.connection.default.username=wuqian@hcs
      remote.connection.default.password=wuqian@891210
      

           the dir is:

           client

                |--Client.java

                |--jboss-ejb-client.properties

       

      but when I run the client it is error:

      what can I do? thanks!

          You are using a wrong JNDI name in your client code which does the lookup. The JNDI bindings show that the module name is wildflyejb3 whereas you are using wildflyejb as the module name during the lookup (that's what the stacktrace suggests).

            Thanks.It is an error.and I user the "wildflyejb3",the error can not be fixed. Sorry for my English.

              I don't see the client code in your post.

              Also how do you start the server?

                thanks! I have fixed it.

                but I not know why?

                my client code is the jboss web code:

                and I delete the jboss-ejb-client.properties

                change the Underline code:  --------------------it work!

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

                        clientProperties.put("remote.connection.default.port", "8080");

                        clientProperties.put("remote.connection.default.host", "localhost");

                        //clientProperties.put("remote.connection.default.username", "ejb");

                        //clientProperties.put("remote.connection.default.password", "wuqian@891210");

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

                        EJBClientContext.setSelector(new ConfigBasedEJBClientContextSelector(new PropertiesBasedEJBClientConfiguration(clientProperties)));

                        Properties properties = new Properties();

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

                        final Context context = new InitialContext(properties);

                user and password are not must!!!

                  Yes that is a different approach.

                  If oyu use the quickstart as is it should work.

                   

                  As long as you run on the same host and have access to the servers directory the LOCAL option is used for authentication by default.

                  See documentation

                    Thanks very much!

                    But why does not it  work for the "jboss-ejb-client" method?

                    This is my "jboss-ejb-client.properties":  and I take it in the same package with the client class. Sorry for my English -:)

                    1. endpoint.name=client-endpoint 
                    2. remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

                      I think that is your problem.

                      You should not pack the properties in a package, simple use the root directory of the classpath
