I trying to use JSP in my portal code. But it is not working. Below is my
code. If anyone can go through my code let me where I am going wrong.
I not worked before with JSP and Portal.
DIRECTORY STRUCTURE:
bookmark - WEB-INF - classes - BookmarkPortlet.class
- portlet.xml
web.xml
jsp - view.jsp
edit.jsp

import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
public class BookmarkPortlet extends javax.portlet.GenericPortlet
{
public void doEdit(RenderRequest request,RenderResponse response)
throws PortletException, IOException
{
response.setContentType("text/html");
String jspName = getPortletConfig().getInitParameter("jspEdit");
PortletURL addUrl = response.createActionURL();
addUrl.setPortletMode(PortletMode.VIEW);
addUrl.setParameter("add","add");
request.setAttribute("addUrl",addUrl.toString());
PortletURL cancelUrl = response.createRenderURL();
cancelUrl.setPortletMode(PortletMode.VIEW);
request.setAttribute("cancelUrl",cancelUrl.toString());
PortletRequestDispatcher rd =
getPortletContext().getRequestDispatcher(jspName);
rd.include(request,response);
}
public void doView(javax.portlet.RenderRequest request,
javax.portlet.RenderResponse response)
throws javax.portlet.PortletException, java.io.IOException
{
response.setContentType("text/html");
String jspName = getPortletConfig().getInitParameter("jspView");
PortletRequestDispatcher rd =
getPortletContext().getRequestDispatcher(jspName);
rd.include(request,response);
}
public void processAction(ActionRequest actionrequest, ActionResponse
actionresponse)
throws PortletException, IOException
{
String removeName = actionrequest.getParameter("remove");
if(removeName != null)
{
PortletPreferences prefs =
actionrequest.getPreferences();
prefs.reset(removeName);
prefs.store();
}
String add = actionrequest.getParameter("add");
if(add !=null)
{
PortletPreferences prefs =
actionrequest.getPreferences();
prefs.setValue(actionrequest.getParameter("name"),
actionrequest.getParameter("value"));
prefs.store();
}
}
}
