Error using home interface in different thread

Using remoting (not the EJB client method with the external properties file) :

Create an InitialContext, pass it to a new thread, look up a home interface for an SLSB, then try to use it to create a remote object in the same thread, the create fails.

Create an InitialContext, perform a home lookup, pass the home to a new thread, try to use it to create a remote object, the create fails.

Look up a home, create a remote from it, and pass to a new thread, SLSB method calls on this remote object fail.

If you perform all these operations in the same thread they are OK.

What error message do you see?

java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:cp-model, moduleName:cp-model.jar, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@4cdada24

Is that the first error message? Yes

Are there any related WARN messages? No

Have you tried searching for that error message? Yes, inconclusively

Is it actually a JBoss error message? “EJBCLIENT000025”

Have you included the deployment descriptors for the application with the problem?

I can supply a server EAR / test client program to recreate

What did you expect to happen?

Remote object found, and SLSB method invoked, without IllegalStateExceptions

How does your application differ from the many examples that work?

It is passing a home reference to a new thread. Our main commercial application is a Swing GUI and it does a lot of this.

Have you enabled DEBUG or TRACE logging to see what is really happening?

Do you have a simple test that reproduces the "bug"? Yes, can supply EAR / JARs on demand but this is the gist of it :

contextProps.put("jboss.naming.client.ejb.context", true);
contextProps.put(Context.SECURITY_PRINCIPAL, usr );
contextProps.put(Context.SECURITY_CREDENTIALS, pwd );
contextProps.put(Context.PROVIDER_URL, "remote://" + url );

final InitialContext ic = new InitialContext( contextProps );
System.out.println( "CPModelClient : main() :... found context");

Thread t1 = new Thread(){

catch ( Exception e )

{ e.printStackTrace(); }
}
};
t1.start();

final CPListSessionHome lihome = (CPListSessionHome) PortableRemoteObject.narrow(ic.lookup( LIST_SLSB_REMOTE_JNDI ), CPListSessionHome.class);
Thread t2 = new Thread(){

catch ( Exception e ) { e.printStackTrace(); }

}
};
