InitialContext.lookup() exception for Stateless session bean

ericgreen Dec 8, 2005 4:30 PM

Hi,

I have JBoss 4.0.3SP1 installed on my local Windows XP Professional machine. I downloaded and deployed the EJB3Trail application and all the examples ran just fine. I then created a simple stateless session bean to try it out for myself:

// local interface
public interface Eric {

 public String[] listFriends();
}

// stateless session bean
@Stateless
public class EricBean implements Eric {

 private String[] friends =
 { "Joe Sessions", "Larry Polnicky", "Laura Mayers",
 "Gary Carbone", "Venkat Koya", "Jay Elrod" };

 public String[] listFriends() {
 return friends;
 }
}

The bean is being deployed correctly as far as I am able to see from the following JBoss server output:

14:55:55,631 INFO [Ejb3AnnotationHandler] found EJB3: ejbName=test.EricBean, class=test.EricBean, type=STATELESS
14:55:55,712 INFO [JaccHelper] test.EricBean has no @SecurityDomain - skipping JACC configuration
14:55:55,722 INFO [JaccHelper] JACC Policy Configuration for deployment has been put in service
14:55:55,722 INFO [Ejb3Deployment] EJB3 deployment time took: 451

However, when I execute the ctx.lookup() call in the following local client code:

// local client code
InitialContext ctx = new InitialContext();
Eric eric = (Eric)ctx.lookup( Eric.class.getName() );

I get the following exception:

Hopefully this will be an easy thing to answer for some of you guys who've used this a bit. Thanks in advance for any help you are able to give!
