    "No EJB receiver" trying to lookup local EJB from java main

    Kevin Stone Newbie

      I am trying to do this in JBOSS 7.1.1. 

      I have written a java main that trys to lookup an ejb and then invoke a method.

      The lookup fails with "No EJB receiver".  I have tried just about every imaginable string for the lookup.

      I tried the ones that are logged to the console when the jar is deployed and those get a "javax.naming.NoInitialContextException: Need to specify class name" exception.

      Thanks for any help anyone can give.

       

       

      The Local interface:

       

      package xxx.accounting;

      import ...

      @Local
      public interface AccountingRetryLocal extends Serializable {
         public void retryFailedRequests() throws NamingException, JMSException;
      }

       

      The Remote interface:

       

      package xxx.accounting;

      import ...

      @Remote
      public interface AccountingRetryRemote extends Serializable {
         public void retryFailedRequests() throws NamingException, JMSException;
      }

       

      The Bean:

       

      package xxx.accounting;

      @Stateless
      public class AccountingRetryBean implements AccountingRetryLocal, AccountingRetryRemote {
         @Override
         public void retryFailedRequests() throws NamingException, JMSException {

         }

      }

       

      The Client Helper:

       

      package xxx.accounting;

      import ...

      public class RetryClientUtil {

         private static final Logger log = Logger.getLogger(RetryClientUtil.class);

         private static Context initialContext;

         public static Context getInitialContext() throws NamingException  {
             if (initialContext == null) {
                  Hashtable<String, String> env = new Hashtable<String, String>();
                  env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.as.naming.InitialContextFactory");
                  env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
                  env.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");
                  initialContext = new InitialContext(env);
              }
              return initialContext;
          }
      }

       

      The Client:  (Run from command line)

       

      package xxx.accounting;

      import ...
      public class AccountingRetry {

         private static final Logger log = Logger.getLogger(AccountingRetry.class);

         public static void main(String[] args) {
             try {
                 Context ctx = RetryClientUtil.getInitialContext();

                 // From EJB example:
                 // ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-the-remote-interface>
                 String appName="";
                 String moduleName="AccountingServices";
                 String distinctName = "";
                 String beanName = AccountingRetryBean.class.getSimpleName();
                 final String interfaceName = AccountingRetryLocal.class.getName();
                 String theName = "ejb:"+appName+"/"+moduleName+"/"+distinctName+"/"+beanName+"!"+interfaceName;

                 AccountingRetryLocal retryLocal = (AccountingRetryLocal) ctx.lookup(theName);
                 retryLocal.retryFailedRequests();
              }
              catch (Exception e) {
                   e.printStackTrace();
              }
          }
      }
