EJB3 jndi lookup failed on JBOSS EAP only due to ProxyFactory not bound

[kevin.yuan]

Hi,

My tests don't have problem with JBOSS 5.1.0 GA community version, it only happens on ENTERPRISE APPLICATION PLATFORM, tests failed during ejb3 sessionbean JNDI lookup, see message below:

So does anyone know what's the real problem? Is there any special configuration for EAP version?

Thanks.

Hi Kevin,

Any questions regarding Enterprise Application Platform should be filed through our customer support portal. Your EAP subscription entitles you to full support of all technologies included.

Please file your issue there. You can find the customer support portal here: https://www.redhat.com/apps/support/.

Issue resolved,

Hi,

I have to deploy an application within various application server environments depending on customer environment. I successfully deploy the application in jBoss 4.2.3, 5.1 and 7.1 final.

I would like to have some "unit-integration" tests to valid my deployment  as fast as I can and test remote EJB invocation and JMS deployment.

I got same issue when trying to invoke a remote EJB deployed within a ear file in JBoss 5.1 from a junit test.

It doesn't matter which  3-part pattern I use (app_name/bean_name/remote) or (app_name/remote-bean_name/qualified_bean_name).

Please note this test is working fine when I deploy this EAR file in jBoss 4.2.3.

I didn't try with jBoss 7.1 yet.

I thought about a classloading issue regarding jboss client jar but it doesn't seems to be the case as I got same issue when changing my test to follow Carlo's classloading tip.

http://wolf-71.blogspot.fr/2010/02/et-phone-home.html

If I change my test to use this classloading mechanism I got an extra exception

java.lang.ClassCastException: org.jboss.jms.client.JBossConnectionFactory cannot be cast to javax.jms.ConnectionFactory

Any suggestion would be appreciated.
