Call EJB from RAP on JBoss [message #63628]

Hi

I have deployed RAP as a war on Jboss
I want to call EJBs through the local interface which are deployed in
an ear on JBoss.

When trying to get an instance of the EJB I have an ClassCastError

Here is the code I use :

InitialContext ctx = new InitialContext();
Object obj = ctx.lookup("TestLocal");
TestLocalHome home = (TestLocalHome) obj;

and the error :

java.lang.ClassCastException: $Proxy85 cannot be cast to
test.interfaces.TestLocalHome

in the file launch.ini of the war I have :

osgi.parentClassloader=app
osgi.contextClassLoaderParent=ccl

Thanks for your help
Val

For those who are interested: this problem was discussed on the equinox
newsgroup.

Val - do you have any interest to share your experiences with the other
RAP devs? Like adding a new FAQ (http://wiki.eclipse.org/RapFaq) entry? :)

Hi

I was glad to help, have added a new faq with name : "How do I remote
call EJB's from an Jboss 4.x AS"

Cheers,
Val
