I cannot get rid of this:
I've a trivial ejb3 stateless session bean.
package com.alblab.ejb3.interfaces;
| // remote interface
|
| import javax.ejb.Local;
|
| @Remote
| public interface RemoteCalculator {
| public double calculate(int a,int b);
| }
//implementation bean
| package com.alblab.ejb3.stateless;
|
| import javax.ejb.*;
| import com.alblab.ejb3.interfaces.RemoteCalculator;
| @Stateless
| public class CalculatorBean implements RemoteCalculator {
| public int calculate(int a, int b){
| return a+b;
| }
| }
I've packed these classes in a jar with extension .ejb3
and deployed it on jboss 4.0.3SP1

Then I tryed to test the stateless session bean with tish client:
//test client
| import java.util.*;
| import javax.naming.*;
| import com.alblab.ejb3.interfaces.*;
| public class Test {
|
| public static void main(String[] args) {
|
| System.setSecurityManager(new SecurityManager(){
| public void checkPermission(Permission p){}
| });
|
| try {
| Properties tab= new Properties();
|
tab.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
| tab.put("java.naming.provider.url","localhost:1099");
|
tab.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
| Context ctx = new InitialContext(tab);
| RemoteCalculator cal= (RemoteCalculator)
ctx.lookup(RemoteCalculator.class.getName());
| int res=cal.calculate(1,1);
| } catch (NamingException e) {
| e.printStackTrace();
| }
| }
|
| }
The client succeds in the lookup operation but fails when the method
"calculate" is invoked with the stack trace that follows:
