[jboss-user] [EJB 3.0] - no local jndi binding for a simple ejb3 session bean
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);
| }
here is the implementation:
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;
| }
| }
this is the servlet where I invoke the EJB bean;
| 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);
| }
|
| }
thanks a lot...
