Hi

I 'm beginner with tomcat and I have a problem with JSP files.
I have tomcat5.0.28 (preconfigured) installed on WINXP OS.
I'm working in ROOT directory (C:\Program\Apache Software Foundation\Tomcat 5.0\webapps\ROOT), this is where all my jsp files are, and my java class-file are in a package called "elie_paket" in "C:\Program\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\WEB-INF\classes\elie_paket "

The problem is that I have a servlet that forwards(request, response) from a jsp file to another.
1- from betyg.jsp-
Code: 
<form action="[URL unfurl="true"]http://localhost:8080/servlet/elie_paket.BetygServlet"[/URL] method="GET">
. It's call the servlet when submitting

2- if everything is ok the theservlet "BetygServet" forwards to "saveit.jsp":
Code: 
"RequestDispatcher rd = request.getRequestDispatcher("saveit.jsp");
	    			 request.setAttribute("elev",elev);
	    			 rd.forward(request,response);"
3- savit.jsp is supposed to receive the request.

The problem is that I receive the follwing msg after submitting from "betyg.jsp":

HTTP Status 404 - /servlet/saveit.jsp
type Status report
message /servlet/saveit.jsp
description The requested resource (/servlet/saveit.jsp) is not available.


"saveit.jsp" looks like that:
Code: 
 <%@page contentType="text/html"%>
<jsp:useBean id="elev" class="StudentBean" scope="request"/>
<jsp:getPropety name="elev" property="*"/>
<html>
  <head>
  <meta http-equiv="Content-Type" content="text/html">
    <title>Inlupp9</title>
  </head>
  
<body>
<h3 style="font-family:verdana; color:red;background-color:lightblue">Studen</h3>
<pre style="font-family:verdana; color:red;background-color:lightblue">
   Namn       : <%= elev.getName()%>
   Tenta Poäng: <%= elev.getPoang()%>
   Tenta Betyg: <%= elev.getBetyg()%>
</pre>

<%@include file ="betyg.jsp"%>
</body>
</html>
and is in "C:\Program\Apache Software Foundation\Tomcat 5.0\webapps\ROOT"

I read about doing something in "C:\Program\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\WEB-INF\web.xml" . But I don't have any idea about what to do.

I appreciate all help.
Thks in advanced

Change :

RequestDispatcher rd = request.getRequestDispatcher("saveit.jsp");

to :

RequestDispatcher rd = request.getRequestDispatcher("/saveit.jsp");

Thanks nor the problem is solved but an other problem came up.
I have the floowing bean, StudentBean:
Code: 
package elie_paket;

  public class StudentBean{
	
    String Namn;
	float tentapng;
	String tentabetyg;
	
	public StudentBean(){
	}
	
	public String getNamn(){
		return Namn;
	}
	
	public float getPoang(){
		return tentapng;
	}
	
	public String getBetyg(){
		return tentabetyg;
	}
	public void setNamn(String Namn){
		this.Namn= Namn;
	}
	
	public void setPoang(float png){
		tentapng=png;
	}
	
	public void setBetyg(String betyg){
		tentabetyg = betyg;
	}
}

and the following JSP, saveit.jsp
Code: 
<%@page contentType="text/html"%>

<html>
  <head>
  <meta http-equiv="Content-Type" content="text/html">
    <title>Inlupp9</title>
  </head>
  
<body>
<h3 style="font-family:verdana; color:red;background-color:lightblue">Föjande student Info sparas:</h3>
<pre style="font-family:verdana; color:red;background-color:lightblue">
<jsp:useBean id="elev" class="elie_paket.StudentBean" scope="request">
 Hello
</jsp:useBean>
   Namn       : <jsp:getProperty name="elev" property="Namn"/>
   Tenta Poäng: <!--jsp:getProperty name="elev" property="tentapng"/-->
   Tenta Betyg: <!--jsp:getProperty name="elev" property="tentabetyg"/-->
</pre>

<%@include file ="betyg.jsp"%>
</body>
</html>

On execution I get the following error
HTTP Status 500 -

--------------------------------------------------------------------------------

note The full stack trace of the root cause is available in the Apache Tomcat/5.0.28 logs.

You have not written the bean correctly - you should change "Namn" to "namn" in the bean.

In the JSP, you should also change "Namn" to "namn", eg :

Code: 
Namn       : <jsp:getProperty name="elev" property="namn"/>
