Servlet problem

[Mark Whitby <ug...@cs.bham.ac.uk>]

Hi all,

Apologies for the stupidity of this email but I'm having a few servlet problems.  I've created the following SearchServlet.java file, compiled it into a class file using Netbeans then copied the class file into my WEB-XML/classes file.  

Now for testing the servlet is very limited but when I try to run the jsp page the page is redirected to http://localhost:8080/WEB-INF/classes/SearchServlet?itemvalue=type+search+criteria+here and not /searchnone.jsp as specified.

Can anyone tell me where I'm going wrong?

Mark

searchitem.jsp:

<table width="100%"> 
<tr>
<td>
 <p class="subhead">Item Search Page</p>
 <p>
  Use this page to search through the different items that we stock.  All searches are done by 

key words.  If using multiple words please use a comma after every different word.</i>.
 </p>
 <p>
 <FORM ACTION="WEB-INF/classes/SearchServlet" METHOD="GET">
     <INPUT TYPE="TEXT" NAME="itemvalue" SIZE="100" VALUE="type search criteria here"><br>
     <INPUT TYPE="SUBMIT">
 </FORM>
 </p>
 <p>
 <a href="search.jsp">Return to the main search page</a>
 </p>
   </td>
   </tr>
   </table>

SearchServlet.java

import java.io.*;

import javax.servlet.*;

public class SearchServlet extends HttpServlet {

    public void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        
        String address = "/searchnone.jsp";
        
        RequestDispatcher dispatcher = request.getRequestDispatcher(address);
        dispatcher.forward(request, response);
    }
    
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }
    
void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }
    

    public String getServletInfo() {
        return "Short description";
    }
}

what filip said, but also...
>From your servlet source code, make sure not to expect a server-side
operation, such as: 

dispatcher.forward(request, response);
 
to result in a client-side 'refresh' to the 'specified' page
(searchnone.jsp, when you obtained the dispatcher).

dispatcher.forward() and .include() are performed as part of the original
request for /WEB-INF/classes/SearchServlet (which filip pointed out is
problematic)
 
Just from the way you phrased your question, I thought you were hoping to
see 'searchnone.jsp' on the address bar, and you won't get that with your
servlet as coded.
