Linking Components from different Ears

jgilbert Dec 27, 2006 11:00 AM

I have SFSB components in multiple Ears. One ear contains a SFSB component that I would like to access from views in all the other Ears. When I tried this I received an exception saying that the JNDI name did not exist.

This is because the components.properties file in the ear has:

jndiPattern my-second-app-0.0.1/#{ejbName}/local

So it is expecting all the components to be in the same Ear. Is there a way around this?

I think you are asking for trouble going the multi-EAR route, but you can certainly resolve the JNDI issue trivially by giving your EJB3 components specific JNDI names using org.jboss.annotation.ejb.LocalBinding.

@Statefule @LocalBinding(jndiBinding="myApp/FooBean") @Name("foo") public class FooBean ...

then your jndi pattern would be myApp/#{ejbName}

Hmmm...

Why do you think this is asking for trouble?

You usually end up with interesting hot deployment classloading issues. I almost always would prefer to have multiple EJB JAR files in a single EAR so that JBoss will treat it as one large application.
