      Hello,
      I am trying to call a web service. I have the following code in my servlet:

      
      /*
       * ServletWSClient.java

      import javax.servlet.http.*;
      
      /**

       /** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
       * @param request servlet request
       * @param response servlet response
       */
       protected void processRequest(HttpServletRequest request, HttpServletResponse response)
       throws ServletException, IOException {
       response.setContentType("text/html;charset=UTF-8");
       PrintWriter out = response.getWriter();
       String s = null;
       try { // This code block invokes the myOperation operation on web service
       s = getEJBWebServiceOneSEIPort().myOperation("fsdqsqdsf");
       } catch(java.rmi.RemoteException ex) {
       ex.printStackTrace();
       } catch(Exception ex) {
       ex.printStackTrace();

       out.println("<html>");
       out.println("<head>");

      I am POSITIVE that the eJBWebServiceOne object implements javax.rpc.Service. because I checked it. Then what's wrong?

      Thanks in advance,

      Julien.

      ps. this is a repost as my message subject line got truncated.
