Jboss 7.1 error on new InitialContext();

[alisissa]

I have been struggling with this error for almost 8 hours and it is becoming really frustrating, so any help here would be really appreciated:

Here is what I am trying:

    final Properties jndiProperties = new Properties();

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

    // create the context

    final Context jndiContext = new InitialContext(jndiProperties);

    Object ref = jndiContext.lookup("ejb:MYApp/MYEjb//gss.myejb.sessions.MySecurityRemote");

and here is my error:

Hi,

your InitialContext is picking up "org.jnp.interfaces.NamingContextFactory" setting/property somewhere.

that was for versions before AS7. check where this is coming in and it will probably solve your problem.

Thanks, I fixed th error using this:

Hashtable jndiProps = new Hashtable();

            jndiProps.put("java.naming.factory.initial", "org.jboss.as.naming.InitialContextFactory");

            InitialContext jndiContext = new InitialContext(jndiProps);

now I got this error:

java.lang.ClassCastException: org.jboss.ejb.client.naming.ejb.EjbNamingContext cannot be cast to org.omg.CORBA.Object

[nickarls]

What are you trying to lookup from where? Remote EJB from standalone client? Show all code and stacktrace you can.

[alisissa]

Hashtable jndiProps = new Hashtable();

jndiProps.put("java.naming.factory.initial", "org.jboss.as.naming.InitialContextFactory");

InitialContext jndiContext = new InitialContext(jndiProps);

Object ref = jndiContext.lookup("ejb:MyApp/MySecurityBean!tpg.myapp.sessions.MySecurityRemote");

MySecurityRemote dao = (MySecurityRemote) PortableRemoteObject.narrow(ref, MySecurityRemote.class);

[nickarls]

Have you compared your attempts with https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI

First guess would be something like the stuff being looked up isn't really a remote interface.

[alisissa]

the stuff being looked up (the beams) are beams from my project, how should i look them up?

[nickarls]

The doc mentions a ?stateful end for the lookup URL for stateful beans. And the remote is @Remote annotated (or otherwise defined as a remote interface)?

[alisissa]

i put this now: Object ref = context.lookup("ejb:myapp//MYbean!gss.myapp.sessions.MySecurityRemote?stateful");

and i am getting this error: java.lang.IllegalStateException: No EJB receiver available for handling [appName:myapp,modulename:,distinctname:] combination

Can you please help

[nickarls]

How is it deployed? WAR? JAR? Check the URL against the app-name and module-name mentioned in the article. Check output of JNDI names at deployment. Then try the code in the lookupRemoteStatelessCalculator in the article

[alisissa]

the file throwing the error is in the war file, and the bean being lookud up is in the jar file.

This is my code now:

final Hashtable jndiProperties = new Hashtable();

jndiProperties.put("java.naming.factory.initial", "org.jboss.as.naming.InitialContextFactory");

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

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

final Context context = new InitialContext(jndiProperties);

Object ref = context.lookup("ejb:myapp//MYbean!gss.myapp.sessions.MySecurityRemote?stateful");

[nickarls]

I checked out the example at

https://github.com/jboss-jdf/jboss-as-quickstart/tree/master/ejb-remote and deployed the jboss-as-ejb-remote-app.jar, resulting in the output

14:38:27,598 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-7) JNDI bindings for session bean named CalculatorBean in deployment unit deployment "jboss-as-ejb-remote-app.jar" are as follows:

          java:global/jboss-as-ejb-remote-app/CounterBean

          java:app/jboss-as-ejb-remote-app/CounterBean

          java:module/CounterBean

Then I imported the client into eclipse and run it. The stateless bean is looked up with

    private static RemoteCalculator lookupRemoteStatelessCalculator() throws NamingException {

        final Hashtable jndiProperties = new Hashtable();

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

        final Context context = new InitialContext(jndiProperties);

       return (RemoteCalculator) context.lookup(

         "ejb:/jboss-as-ejb-remote-app/CalculatorBean!" + RemoteCalculator.class.getName()

      );

    }

and the stateful with

    private static RemoteCounter lookupRemoteStatefulCounter() throws NamingException {

        final Hashtable jndiProperties = new Hashtable();

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

        final Context context = new InitialContext(jndiProperties);

      return (RemoteCounter) context.lookup(

         "ejb:/jboss-as-ejb-remote-app/CounterBean!" + RemoteCounter.class.getName()+"?stateful"

      );

    }

That was from SE -> EJB JAR. Perhaps there is a simpler way from WAR -> EJB JAR but perhaps that's a starting point.

[nickarls]

For a WAR, you might try injecting a

@EJB(lookup = "ejb:/jboss-as-ejb-remote-app/CounterBean!org.jboss.as.quickstarts.ejb.remote.stateful.RemoteCounter?stateful")

private RemoteCounter;

I didn't set up my test completely but I think I got a hit on the lookup...

[alisissa]

jboss-as-ejb-remote-app should be replaced by myapp (the jar file)?

and this should be left the same org.jboss.as.quickstarts.ejb.remote.stateful?

[nickarls]

"ejb:/myapp/MYbean!gss.myapp.sessions.MySecurityRemote?stateful"

if MySecurityRemote is the remote interface for MYbean.

I verified the remote EJB injection into a Servlet and saw
