https://community.jboss.org/message/749623#749623 -------------------------------------------------------------- Hi We have a Utility class with the following code inside it. private static Hashtable<String, String> initContextEnv = new Hashtable<String, String>(); private static final String PKG_INTERFACES = "org.jboss.ejb.client.naming"; public static final String PROPERTY_PROVIDER_URL_VALUE = "remote://localhost:4447"; public static final String JNDI_PREFIX = "ejb:my_beans/my_beans//"; initContextEnv.put(Context.URL_PKG_PREFIXES, PKG_INTERFACES); initContextEnv.put(Context.PROVIDER_URL, PROPERTY_PROVIDER_URL_VALUE); initialContext = new InitialContext(initContextEnv);     public final <T> T getEJB(Class<T> beanClass) throws NamingException {         String ejbName = beanClass.getSimpleName() + IMPL;         String remoteInterfaceName = beanClass.getName();         String jndiName = JNDI_PREFIX + ejbName + "!" + remoteInterfaceName;         Object ref = initialContext.lookup(jndiName);         return beanClass.cast(ref);     } All my stateless session beans are there in the my_beans.jar file which is deployed on server instance 1 as below: Server instance1 my_beans.ear   |---------------my_beans.jar   |---------------my_persistence_beans.jar *When I deploy my second application on the same server instance then it works fine* and I am able to succesfully invoke methods on these stateless session beans *using the above utility class.* Server instance 1 my_application_one.ear |---------------my_application.war |---------------META_INF                        |----------------jboss-deployment-structure.xml Wherein the jboss-deployment-structure.xml has the following contents: <?xml version='1.0' encoding='UTF-8'?> <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">   <ear-subdeployments-isolated>false</ear-subdeployments-isolated>   <deployment>     <dependencies>         <module name="deployment.my_beans.ear.my_beans.jar" export="true" />         <module name="deployment.my_beans.ear.my_persistence_beans.jar" export="true" />     </dependencies>   </deployment> </jboss-deployment-structure> But when I try to invoke methods on these stateless session beans from other server instance it throws an exception Server Instance 2: my_application2.ear

Do I need to include some jar? I have tried various ways to access EJBs by googling and implementing those solutions but nothing was fruitful. Need some directions :( attached is my standalone.xml file. I am using JBOSS7.1 migrating my application from JBOSS4.2. I have created the second server instance by copying the standalone folder of JBOSS. and then giving the server base directory while starting the second server instance as the renamed and copied standalone folder. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/749623#749623] Start a new discussion in JNDI and Naming at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
