EJB showstopper - javax.ejb.EJBException: Deprecated

[philbigdog]

Hi - usual story, new to this etc. - just trying to get a simple session bean example up and running. Works fine up to calling the remote bean method (which just returns a String).
The returned errors are extremely ambiguous - see below.
Cheers.

From the client:
Name = Demo
Got initial context
Got reference.
Got Bean's Home interface reference.
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.ServerException: Bean exception. Notify the application administrator; nested exception is:
javax.ejb.EJBException: Deprecated

From the console:

As the javadocs say, use

new InitialContext().lookup("java:comp/env");

Many thanks for the reply - I've now read the errata to the EJB 1.1 but I'm still struggling - my client is:

package ejb.demo;
import javax.naming.Context;
import javax.naming.InitialContext;
import ejb.demo.Demo;
import ejb.demo.DemoHome;

public class DemoClient
{
public static void main(String[] args)
{
try
{
Context initContext = new InitialContext();
Context ctx = (Context)initContext.lookup("java:comp/env");
DemoHome dHome = (DemoHome) ctx.lookup( "ejb/demo/Demo" );
Demo lDemo = dHome.create();
// Do anything with the Demo Entity
int lId = lDemo.hashCode();
System.out.println( "Hashcode is: " + lId );
lDemo.remove();
}
catch ( Exception e )
{
e.printStackTrace();
}
}
}

...but it fails on the "java:comp/env" lookup, the error is shown below - Do I need some extra configuration to ejb-jar.xml to fix this ?
Many thanks for your help !

My ejb-jar.xml:
<?xml version="1.0" encoding="UTF-8"?>

<ejb-jar>
JBoss Demo Application
<display-name>Demo EJB</display-name>
<enterprise-beans>

<ejb-name>ejb/demo/Demo</ejb-name>
ejb.demo.DemoHome
ejb.demo.Demo
<ejb-class>ejb.demo.DemoBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>

</enterprise-beans>
</ejb-jar>

(Error from DemoClient below):

javax.naming.NameNotFoundException: comp not bound

The java:comp/env namespace is for use inside the bean.

You cannot access it from a client.

Hi,

Have a look at the free 'getting started' PDF which will give you examples of clients outside the Jboss JVM doing a JNDI lookup:

I also got this error with Sun EJB tutorial. I fixed it by making this code in comment in DemoBean.java:

public void setSessionContext(SessionContext ctx) {
/*if (verbose)
System.out.println("setSessionContext called");
this.ctx = ctx;
props = ctx.getEnvironment();*/
}
