无法参数化ejb函数

@Stateless

public class AnotherBean {

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

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

}
}

并使用servlet调用它

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

public void test(String i)

servlet和EJB都已部署,但仍然 服务器给出错误

  WARNING: StandardWrapperValve[HelloEjb]: PWC1406: Servlet.service() for servlet 
  HelloEjb threw exception
  java.lang.NoSuchMethodError: enew.AnotherBean.newTest(Ljava/lang/String;)V

    at javax.servlet.http.HttpServlet.service(HttpServlet.java:734)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:847)
