I have a JSR168 portlet. I want to call a servlet on it.
1 ) in doview - I dispatch to my servlet that I created it before.
Now I want to , in my servlet - in doGet part , dispatch to a jsp page.
Part one is ok(means : dispatch portlet to servlet) but I have problem with second part, when I want to dispatch in my servlet to a .jsp file.
Please guide me.
here is my code:
============================================================
view.jsp
<%@ page import="javax.portlet.PortletPreferences" %>

JSPPortlet - doView part
protected void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException {
response.setContentType("text/html");
PortletPreferences prefs = request.getPreferences();
System.out.println("**************************************");
System.out.println(request.getParameter("text"));
String x = request.getParameter("text");
System.out.println("X = " + x);
if((null == x) || ("" == x))
{
System.out.println("x is null.");
PortletRequestDispatcher dispatcher1 = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/view.jsp");
dispatcher1.include(request, response);
}
else{
PortletRequestDispatcher dispatcher = getPortletContext().getRequestDispatcher("/DisplayImg");
dispatcher.include(request, response);
System.out.println("inja elseeeeeeeeeeee view"+request.getParameter("text"));
}
