Session maintenance with j2ee generated stub
Hello,
I am trying to maintain state between a JSE endpoint and a servlet that acts as a client.
Here is the code for the client:
/*
* addClient.java
*
* Created on May 22, 2006, 8:44 PM
*/
package pack;
import java.io.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.xml.rpc.Stub;
/**
*
* @author julien
* @version
*/
public class AddClient 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();
try { // This code block invokes the add operation on web service
int sum = getAdderWebServiceSEIPort().add(4);
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet addClient</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet addClient at " + sum + "</h1>");
out.println("</body>");
out.println("</html>");
out.close();
} catch(java.rmi.RemoteException ex) {
// TODO handle remote exception
} catch(Exception ex) {
// TODO handle custom exceptions here
}
}
// <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.AdderWebService getAdderWebService() {
pack.AdderWebService adderWebService = null;
try {
javax.naming.InitialContext ic = new javax.naming.InitialContext();
adderWebService = (pack.AdderWebService) ic.lookup("java:comp/env/service/AdderWebService");
} catch(javax.naming.NamingException ex) {
ex.printStackTrace();
}
return adderWebService;
}
private pack.AdderWebServiceSEI getAdderWebServiceSEIPort() {
pack.AdderWebServiceSEI adderWebServiceSEIPort = null;
try {
Stub stub;
adderWebServiceSEIPort = getAdderWebService().getAdderWebServiceSEIPort();
stub = (Stub)adderWebServiceSEIPort;
stub._setProperty(javax.xml.rpc.Stub.SESSION_MAINTAIN_PROPERTY, true);
adderWebServiceSEIPort= (pack.AdderWebServiceSEI)stub;
} catch(javax.xml.rpc.ServiceException ex) {
ex.printStackTrace();
}
return adderWebServiceSEIPort;
}
}
and here is the code for the JSE endpoint:
package pack;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
import javax.xml.rpc.ServiceException;
import javax.xml.rpc.handler.soap.SOAPMessageContext;
import javax.xml.rpc.server.ServiceLifecycle;
import javax.xml.rpc.server.ServletEndpointContext;
/**
* This is the implementation bean class for the AdderWebService web service.
* Created May 22, 2006 8:30:25 PM
* @author julien
*/
public class AdderWebServiceImpl implements AdderWebServiceSEI, ServiceLifecycle{
ServletEndpointContext endptCtx;
SOAPMessageContext msgCtx;
/**
* Web service operation
*/
public int add(int number) throws java.rmi.RemoteException {
System.out.println("add called");
HttpSession session = endptCtx.getHttpSession();
System.out.println("SESSION ID "+session.getId());
if(session !=null){
System.out.println("session not null");
String idFromClient = msgCtx.getProperty("id").toString(); System.out.println("----"+idFromClient);
String id = (String)session.getAttribute("id"); System.out.println("----"+id);
if (id!= null && idFromClient.equals(id)){
System.out.println("nested non null");
int total = (Integer)session.getAttribute("total") + number;
session.setAttribute("total",total);
return total;
} else{
System.out.println("nested null");
session.setAttribute("id", idFromClient);
int total = number;
session.setAttribute("total",total);
System.out.println("here"+session.getAttribute("id"));
return total;
}
} else{
System.out.println("session null");
return 0;
}
}
public void init(Object context) throws ServiceException {
System.out.println("init called");
endptCtx = (ServletEndpointContext) context;
msgCtx = (SOAPMessageContext)endptCtx.getMessageContext();
}
public void destroy() {
System.out.println("destroy called");
}
}
Here is the output from the console:

As you can see, I have enabled session maintenance and still it does not work. FYI, I use Jboss 4.0.3. Can anyone help please??
Thanks in advance,
Julien.
