Question

I can write a ejb like this…

@Stateless

public class AnotherBean {

@PersistenceContext(unitName = "VoidJPA-ejbPU")
private EntityManager em;

public void newTest() {
    System.out.println("Testing");

}
}

And call it using this from a servlet

@EJB
private AnotherBean nsb;
...
...
nsb.newTest();

But whenever i put a variable into newTest() i cannot access it

public void test(String i)

The servlet and EJB are both deployed but still
the server gives the error

  WARNING: StandardWrapperValve[HelloEjb]: PWC1406: Servlet.service() for servlet 
  HelloEjb threw exception
  java.lang.NoSuchMethodError: enew.AnotherBean.newTest(Ljava/lang/String;)V
    at jpa.HelloEjb.processRequest(HelloEjb.java:44)
    at jpa.HelloEjb.doGet(HelloEjb.java:85)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:734)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:847)
  .....
  ........
  ......

Any Help

Thanks

Ya i got it…

In netbeans i had to do the following…

1. Clean and Build the Ejb Project

2. Deploy the Ejb Project

3. Deploy the WebApplication(war) project (and make sure the ejb jar is in libraries which netbeans automatically does and needs no worry).
