Hello!
I´m a totaly newbie in programming with EJB3.0
So I tried a very easy tutorial for Stateful SessionBeans.
I always get an "Exception in thread "main" java.lang.NoClassDefFoundError:
Lorg/jboss/invocation/Invoker"
| Exception in thread "main" java.lang.NoClassDefFoundError:

Here are my codes:

|
| @javax.ejb.Stateful
| public class CalculatorSession implements ICalculator, Serializable {

|
| public CalculatorSession(){

| }

| return a+b;
| }
|
| public int last() {
| return last;
| }
| }
|
ICalculator
| package calculator;
|
| @javax.ejb.Remote
| public interface ICalculator{
| public int add(int a, int b);
|
| public int last();
| }
|
calcClient
| package client;
|
| import java.util.Properties;
| import javax.naming.InitialContext;
| import calculator.*;
|
| public class calcClient {
|
| public static void main(String[] args) throws Exception {
|
| Properties p = new Properties();
|
p.put("java.naming.factory.inition","org.jnp.interfaces.NamingContextFactory");
|
p.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
| p.put("java.naming.provider.url","jnp://localhost:1099");
| InitialContext ctx = new InitialContext(p);
| ICalculator calc = (ICalculator)
ctx.lookup("CalculatorSession/remote");
|
| System.out.println("2 + 1 = " + calc.add(2,1));
| System.out.println("LAST: " + calc.last());
|
| System.out.println("2 + 4 = " + calc.add(2,4));
| System.out.println("LAST: " + calc.last());
| }
| }
|
I installed:
JBOSS AS 4.0.4
JBossIDE 2.0.0.Beta2
Eclipse 3.2.1
Many Thanks
