Java EE (Java Enterprise Edition) General Discussion

Hello world,
I have got the problem to transfer euro (?) characters correctly from a jsp to the controller servlet. The controller recieves the euro (?) caharcter as a question mark (?). Obvoiusly this forum has got the same problem :-) !!!!!

The jsp has code like following:

<form name="PruefungAnlegen" method="get" action="PruefungServlet" target="_parent">
....
<textarea name="titel" style="width: 750px;" rows="5" maxlength="1000" wrap="VIRTUAL" length="40"><%=pruefung.fehler(pruefung.getTitel())%></textarea></td>...<td width="850" align="center"><input type="hidden" name="pruefungAnlegen" value="anlegen"/>
...
<a href="javascript:document.PruefungAnlegen.submit()" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('PAnlegen','','../../images/<%out.print(login.getLokalisierung("Sprache"));%>/navbuttons/PAnlegenNavP.gif',1)"><img src="../../images/<%out.print(login.getLokalisierung("Sprache"));%>/navbuttons/PAnlegenNav.gif" alt="<%out.print(login.getLokalisierung("Sprache.Button.Pruefung.PruefungAnlegen.Alt"));%>" name="PAnlegen" width="120" height="23" border="0"></a>

Here is the Controller Code.

/** 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 { 
       ServletContext application = getServletContext();        HttpSession session = request.getSession();
       String key = null;      // Key, which will be saved in the HashMap parameter.        
       String adresse = "/pruefung/anlegen/prfEinController.jsp?x=y";                //Load all keys and save them in a HashMap for further Steps.        
        Set s = this.parameter.keySet();        Iterator i = s.iterator();                
        while(i.hasNext()){            
               key = (String)i.next();           
               System.out.println("Key: "+key);              
               System.out.println("Value: "+request.getParameter(key)); //!!!!!!!!!!!!!!!!!!!!!!!!!!! This Line Shows the ? as a ?!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!            
               this.parameter.put(key, h.stringFiltern(request.getParameter(key), "Pruefung"));        
        }        
        key = null;                        

        // Read the HashMap and assemble the target-adress. I know, it could be more sophisticated, but my major problem is five lines above ;-)        
         i = s.iterator();        
         while(i.hasNext()){            
                  key = (String)i.next();            
                  adresse = adresse+"&"+key+"="+this.parameter.get(key);        
         }                

        // Redirect to another Controller.
        RequestDispatcher dispatcher = application.getRequestDispatcher(adresse);        
        dispatcher.forward(request, response);            
}

I would be more than grateful if anyone could help me.

Thanks a lot.
