EJB3 interfaces questions

[pablojavierpy]

Hi all,

I have a Session Bean that looks like this:

public @Stateless class ReverseBean implements Reverse {

 public String reverse(String s)
 {
 String ret;
 // code to reverse the string "s" here
 return ret;
 }

}

And then, I have its corresponding interface:

@Remote
@Local
public interface Reverse {
 public String reverse(String s);
}

I have five small questions:
1) Is it OK to use only ONE class as remote AND local interface?
2) What's the default JNDI name assigned to the Session Bean? That is, how am I suppose to do the lookup for the Session Bean in the Initial Context?
3) Can I use @EJB injection in Servlets or injections are only available to other EJBs?
4) Where should I specify the "client-jar" if I am using EJB3? Do I even need a "client-jar"?
5) Where can I find more documentation about these three previous questions?

I am using JBoss 4.0.5.GA, installed with the installer, and the original EJB3 RC9 that comes with it.

1) Nope. I would recommend keeping the methods in your interface "Reverse", then make a couple of children, "ReverseLocal" and "ReverseRemote", and making these your @Local and @Remote APIs.

2) Depends on your packaging.

http://docs.jboss.org/ejb3/app-server/tutorial/jndibinding/jndi.html

...shows the defaults.

http://jboss.org/wiki/Wiki.jsp?page=DisplayTheJDNITreeWithTheJMXConsole

... shows how to see what's actually in the JNDI Tree.

3) Servlet injection is not currently supported, though will be in the future.

4) You mean the JAR that contains all the classes needed of an EJB3 client? Everything you need should be in $JBOSS_HOME/client, most notably the jboss-all-client.jar and the EJB3 JARs.

5) http://trailblazer.demo.jboss.com/EJB3Trail/

...and

http://docs.jboss.org/ejb3/

...which is a little outdated.
