Can I lookup a different service from a service without @EJB?

Hey guys. The subject of this thread is ugly, I know. Pardon me, my english
is very poor.

I know I can use @EJB. Is simpler, easier and cleaner. But this question
appeared in the team. With JBoss, if I'm in SessionBean A and I need
SessionBean B, I must call the ServiceLocator. How can I do that with
OpenEJB? I tied this:


> // SessionBean A looking up SessionBean B
> Properties properties = new Properties();
> properties.setProperty(Context.INITIAL..., "RemoteInitialContextFactory");
> properties.setProperty(Context.PROVIDER_URL, "ejbd://10.1.1.2:4201");
> 
> // 10.1.1.2 is where the server is started, using openejb start
> --ejbd-bind.

> ctx.lookup("SessionBeanBRemote");

Apparently, it can't locate SessionBeanB. What am I doing wrong?

Thanks in advance,
Regards,
Andre.

it works but your properties are false. You should provide the qualified
name of the factory.

This doc has some info.

   http://openejb.apache.org/3.0/service-locator.html

If the two beans are in the same vm you can use the org.apache.openejb.client.LocalInitialContextFactory instead and leave out the Context.PROVIDER_URL.
