Hi!
 
I successfully deployed a simple EJB 3.
 
Here is the code:
 
{code}
package ejb;
 
import javax.ejb.Remote;
 
@Remote
public interface HelloWorld {
    public String sayHello(); 
}
 
 
 
package ejb;
 
import javax.ejb.Stateless;
import ejb.HelloWorld;
 
public @Stateless class HelloWorldBean implements HelloWorld {
    public String sayHello()
    {
        return "Hello world...";
    } 
}
{code}
 
 
The deployment tells me about the following bindings:
 
{code}
  java:global/MyEJBProject/HelloWorldBean!ejb.HelloWorld
  java:app/MyEJBProject/HelloWorldBean!ejb.HelloWorld
  java:module/HelloWorldBean!ejb.HelloWorld
  java:jboss/exported/MyEJBProject/HelloWorldBean!ejb.HelloWorld
  java:global/MyEJBProject/HelloWorldBean
  java:app/MyEJBProject/HelloWorldBean
  java:module/HelloWorldBean
{code}
 
 
Looking up from a standalone client works:
 
{code}
import java.util.Properties;
 
import javax.naming.Context;
import javax.naming.InitialContext;
 
import ejb.HelloWorld;
import ejb.HelloWorldBean;
 
public class Client {
 
    public static void main(String[] args) {
        try {
            Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY,
                    "org.jboss.naming.remote.client.InitialContextFactory");
            env.put(Context.PROVIDER_URL, "remote://localhost:4447");
            env.put(Context.SECURITY_PRINCIPAL, "xxx");
            env.put(Context.SECURITY_CREDENTIALS, "xxx");
            env.put("jboss.naming.client.ejb.context", true);
 
            Context ctx = new InitialContext(env);
            HelloWorld hello = (HelloWorld) ctx.lookup("MyEJBProject/HelloWorldBean!ejb.HelloWorld");
 
            System.out.println("EJB says: " + hello.sayHello());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
{code}
 
 
But invocation from a servlet results in error messages due to unsuccessful lookups.
 
I tried:
 
{code}
protected void doGet(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    try {
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
 
        Context ctx = new InitialContext();
        HelloWorld hello = (HelloWorld) ctx
                .lookup("MyEJBProject/HelloWorldBean!ejb.HelloWorld");
 
        out.println("EJB says: " + hello.sayHello());
    } catch (Exception e) {
        e.printStackTrace();
    }
 
}
{code}
 
Any idea?
