No EJB client context is available

[suman.ganta]

On JBoss AS7.1, When I tried to invoke an EJB from a web app which has ejb-ref to that attribute, it works fine.

However, when I lookup JNDI for that EJB, although it succeeds to look it up, it fails upon invoking any method on the returned proxy with the following error:

java.lang.IllegalStateException: No EJB client context is available

I tried to lookup all reachable JNDIs for the EJB, lookup succeeds but the method invocation on the returned proxy fails always. I tried it by not closing InitialContext as well, but did not help. Is this a an existing bug? or do I have to do something different to get around this problem?

This is the case with both EJB2.x and EJB3 lookups.

Access to EJBs is different in AS7 see [1], for JNDI you should have a look at [2]

Yeah, I saw all those articles. In my case, both my webapp and the ejb are deployed together as ear. And I'm looking up with the below code -

InitialContext context = new InitialContext();

Object obj = context.lookup("java:global/<appname>/<ejbjar-name>/<ejb name>!<interface>");

MyInterface myejb = (MyInterface) obj;

The lookup works fine. Issue is with invoking methods on myejb object. It always fails with the exception mention in my first post.

Why do you don't use injection and let the container do the work for you?

[suman.ganta]

No luck. I tried that too now. I annotated my ref with @EJB and  it is being injected by the container properly (just like how the lookup was working properly) but, upon invoking a method on it, i get the same "No EJB client context is available exception".

Here is the whole situation -

my webapp receives a request, which instantiates a class A (packaged along with ejb jar). Class A has a ejb reference (@EJB(beanInterface=ICounterStore.class)) to an EJB packaged in the same jar.

Here is the EJB definition -

@Stateless

@Remote(ICounterStore.class)

public class CounterStoreBean implements ICounterStore

{

}

Please post the entire exception stacktrace.

This smells like you're doing these lookups in a new thread that you (or a library you use) created.

I don't think you can do that.

JNDI lookups from Quartz Scheduler jobs is a typical offender here.

Do you by chance have jndi.properties in your classpath (lib)?
