Hi,
here is a simple Code sample to achieve this (as stated by Praveen Gudapati I use response.sendRedirect):
<%@ page language="java" %>
<%
    String redirectURL = request.getParameter ("redirectURL");
    response.sendRedirect (redirectURL);
%>
In this sample you can even pass the redirectURL as URL Parameter. If you don't want that just define
a static String for redirectURL.
If you use this within a portal component and want to call a "local" JSP I'd prefer to use a forward. This is faster and your Clients won't have to initiate a new request:
Here's some sample code:
public class MyPortalComponent extends AbstractPortalComponent
private static final String PATH_INDEX_JSP = "jsp/index.jsp";
* Forward the request to the corresponding JSP.
* @param request The request.
* @param response The response.
private final void forwardToJSP(IPortalComponentRequest request, IPortalComponentResponse response, String jspPath)
  // get the JSP as resource object and include it in the response
  IResource jspResource = request.getResource(IResource.JSP, jspPath);
  response.include(request, jspResource);
public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
forwardToJSP(request, response,PATH_INDEX_JSP);
So when you have more than one JSP you just use a URL Parameter and switch Case in doContent to call the appropriate JSP:
Example:
public class MyPortalComponent extends AbstractPortalComponent
private static final String PATH_INDEX_JSP = "jsp/index.jsp";
private static final String PATH_SECOND_JSP = "jsp/second.jsp";
private static final String PATH_THIRD_JSP = "jsp/third.jsp";
private final int getRequestAction(IPortalComponentRequest request) {
          int value = 0;
          String param = request.getParameter("request_action");
          if (param != null) {
            try {
               value = Integer.parseInt(param);
            } catch (NumberFormatException e) {
               value = 0;
          return value;
public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
// get the requested action
int request_action = getRequestAction(request);
switch (request_action) {
  case 0 :                    
    forwardToJSP(request, response,PATH_INDEX_JSP);
    break;
  case 1 :       
    forwardToJSP(request, response,PATH_SECOND_JSP);          
    break;
  case 2 :
    forwardToJSP(request, response,PATH_THIRD_JSP);          
    break;
  default :     
    forwardToJSP(request, response, PATH_INDEX_JSP);
    break;
Hope this helps
