Hello,
I am trying to call a web service. I have the following code in my servlet:
/*
* ServletWSClient.java
*
* Created on 9 mai 2006, 12:32
*/
package pack;
import java.io.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.*;
/**
*
* @author Administrator
* @version
*/
public class ServletWSClient extends HttpServlet {
/** 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>");
out.println("<title>Servlet ServletWSClient</title>");
out.println("</head>");
out.println("<body>");
out.println(s);
out.println("<h1>Servlet ServletWSClient at " + request.getContextPath () + "</h1>");
out.println("</body>");
out.println("</html>");
out.close();
}
// <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code.">
/** Handles the HTTP <code>GET</code> method.
* @param request servlet request
* @param response servlet response
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/** Handles the HTTP <code>POST</code> method.
* @param request servlet request
* @param response servlet response
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/** Returns a short description of the servlet.
*/
public String getServletInfo() {
return "Short description";
}
// </editor-fold>
private pack.EJBWebServiceOne getEJBWebServiceOne() {
pack.EJBWebServiceOne eJBWebServiceOne = null;
//System.out.println("-->"+eJBWebServiceOne.getClass().getInterfaces().toString());
try {
javax.naming.InitialContext ic = new javax.naming.InitialContext();
eJBWebServiceOne = (pack.EJBWebServiceOne) ic.lookup("java:comp/env/service/EJBWebServiceOne");
} catch(javax.naming.NamingException ex) {
ex.printStackTrace();
}
return eJBWebServiceOne;
}
private pack.EJBWebServiceOneSEI getEJBWebServiceOneSEIPort() {
pack.EJBWebServiceOneSEI eJBWebServiceOneSEIPort = null;
try {
eJBWebServiceOneSEIPort = getEJBWebServiceOne().getEJBWebServiceOneSEIPort();
} catch(javax.xml.rpc.ServiceException ex) {
ex.printStackTrace();
}
return eJBWebServiceOneSEIPort;
}
}
Here is what I get:

I am POSITIVE that the eJBWebServiceOne object implements javax.rpc.Service. because I checked it. Then what's wrong? I use Jboss 4.0.3
Thanks in advance,
Julien.
