Hi guys!
I have developed a very simple EJB with the JBoss IDE 1.5:
Here is the EJB:
Interface:
| package src;
|
| import javax.ejb.Remote;
|
| @Remote
| public interface MyCalculator
| {
| int add(int x, int y);
|
| int sub(int x, int y);
| }
|
Implementation:
| package src;
|
| import javax.ejb.Stateless;
| import src.MyCalculator;
|
| public @Stateless class MyCalculatorBean implements MyCalculator {
|
| public int add(int x, int y)
| {
| return x+y;
| }
|
| public int sub(int x, int y)
| {
| return x-y;
| }
|
| }
|
jndi.properties:
| java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
| java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
| java.naming.provider.url=localhost:1099
|
It deployed successfully.
Next I developed the client.
First I got some ClassNotFoundException for the class EJBMetaDataImpl. Luckily
that problem could be solved as I found another thread stating that the client
project needs the jboss-client.jar.
Here ist the client:
| import java.rmi.RMISecurityManager;
| import java.util.Enumeration;
| import java.util.Hashtable;
|
| import javax.naming.Context;
| import javax.naming.InitialContext;
|
| import src.MyCalculator;
|
| public class MyCalculator_Client
| {
|
| /**
| * @param args
| */
| public static void main(String[] args)
| {
| try
| {
| System.setSecurityManager(new RMISecurityManager());
| InitialContext ctx = new InitialContext();
|
| MyCalculator myCalculator = (MyCalculator) ctx
| .lookup("MyCalculatorBean/remote");
|
| System.out.println("1+2=" + myCalculator.add(1, 2));
|
| } catch (Exception e)
| {
| e.printStackTrace(System.err);
| }
| }
|
| }
|
Here is the exception during invocation:

Any idea?
