I'm trying to perform a JNDI lookup on a local stateless session bean.
When I use the jboss jmx console to check the JNDI name space I get the following:
anonymous wrote : +- HandleDelegate (class:
org.jboss.proxy.ejb.handle.HandleDelegateImpl)
| +- ORB (class: org.jacorb.orb.ORB)
| +- env (class: org.jnp.interfaces.NamingContext)
| | +- ejb (class: org.jnp.interfaces.NamingContext)
| | | +- DddEJBBeanLocal[link -> local/DddEJBBean@16619879] (class:
javax.naming.LinkRef)
| | +- DddEJBRemoteHome[link -> DddEJBBean] (class: javax.naming.LinkRef)
The code I am using for the JNDI lookup is as follows:
private DddEJBLocal lookupDddEJBBean() {
| try {
| Context c = new InitialContext();
| DddEJBLocalHome rv = (DddEJBLocalHome)
c.lookup("java:comp/env/ejb/DddEJBBeanLocal");
| return rv.create();
| } catch (NamingException ne) {
|
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE,
"exception caught", ne);
| throw new RuntimeException(ne);
| } catch (CreateException ce) {
|
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE,
"exception caught", ce);
| throw new RuntimeException(ce);
| }
| }
The ejb-jar.xml is as follows:
<?xml version="1.0" encoding="UTF-8"?>
| <ejb-jar version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee"

I get the the following error:

QUESTION#1:
What is wrong with my lookup code or the ejb-jar.xml configuration?
QUESTION#2
Are proprietary JBoss configuration files (e.g., jboss.xml) required in order to
successfully perform a JNDI lookup on the above mentioned bean?
Thanks for any help! --sd
