hi all,
I got java.lang.NullPointerException when I was calling a simple ejb3 staless session been (deployed to jboss4.04GA) from my servlet, my web application and the ejb were packeged in the same ear. during the deployment I can't see a local jndi binding for this bean as well.

just wodering, do I need to configure something for this bean in ejb-jar.xml or jndi.properties as I think by default session beans will bind to JNDI in the form ejbName/remote for remote interfaces and ejbName/local in the case of local interfaces


here is the ejb interface:

package src.reg.server;
import javax.ejb.Local;

@Local()
public interface token {

 public String issue(String uid, String PIN);
}

package src.reg.server;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

@Stateless()
public class tokenAction implements token {
public String issueKey(String username,String pin)
 {
 String temp = username +pin;
 return temp;
 }
}

package src.reg.server;

import java.text.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import javax.ejb.EJB;

public class myservlet extends HttpServlet {

 @EJB
 private static token t;
 private String key = null ;

 protected void doPost(HttpServletRequest req, HttpServletResponse resp)
 throws ServletException,
 IOException {
 resp.setContentType("text/plain");
 PrintWriter out = resp.getWriter();
 String uid = req.getParameter("uid");
 String Pin = req.getParameter("passwd");
 key = t.issueKey(uid, Pin);//(here is the exception was thrown) out.println(key);
 }

}
