1. Re: EJB client jars
atorres Oct 9, 2002 11:07 AM (in response to eemrich)I can´t understood why you need the client jar on the web application. You could declare a reference on the sun-j2ee.xml to the outter EJB like:
<ejb-ref>
<ejb-ref-name></ejb-ref-name>
<jndi-name><jndi-name></jndi-name>
</ejb-ref>
Also, incude the ejb-ref on the web.xml:
<ejb-ref>
<ejb-ref-name></ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
...
...
<ejb-link></ejb-link>
</ejb-ref>
them you have to include on the war-ic.war the home and interface classes of your beans (or a reference to them on the manifest)
Hope it helps! -

No, Java can't do any magic and needs .classes of the bean but not all of them.

Yes, it works fine if you don't care about jar size.
You need some Jboss libraries, too (ones from %jbossdir%/client as I recall.) As I understood, these libraries contain "universal" RMI stubs for beans. -

agilbert201 Oct 22, 2002 7:13 PM (in response to eemrich)Does one infer from this that JBoss can not generate a client jar per Spec? Ie using
<ejb-client-jar>
in ejb-jar.xml -
5. Re: EJB client jars
sgturner Oct 23, 2002 12:15 AM (in response to eemrich)Due to JBoss superior architecture over the "other" app servers, there is no need to generate stubs and skeletons. JBoss makes heavy use of reflection and dynamic proxies. Almost any object you get out of Jndi is a dynamic proxy object whose invocation handler implements the correct interfaces. Follow these instructions for packaging your ejbs:
http://www2.theserverside.com/resources/articles/J2EE-Deployment/chapter.html
If your client is running in a JVM that is not the same JVM that JBoss runs in, use the jboss/client jars in your class path, plus your own interfaces.
