1. Re: Restricting link & form actions within the same portlet
bvogt Nov 16, 2006 7:56 AM (in response to girishramagiri)Have you considered an integration of your application by an iframe tag?
Unfortunately this may cause some (ugly) scrollbar issues...

3. Re: Restricting link & form actions within the same portlet
girishramagiri Nov 16, 2006 11:53 AM (in response to girishramagiri)Hi Thomas,
Thanks for your input.
Inorder to use PortletURL, I need to extend PortalJSP & use portlet taglib in the jsp which has the buttons.
After extending the PortalJSP & incorporating portlet taglib, the existing jsp along with the existing tags looks as below:<%@ page language="java" extends="org.jboss.portal.core.servlet.jsp.PortalJsp" %> <%@ page language="java" pageEncoding="UTF-8"%> <%@ page import="com.myapp.web.user.bean.User" %> <%@ page import="com.myapp.web.utility.apputils.component.AppConstants" %> <%@ page import="com.myapp.web.utility.apputils.component.ActionConstants"%> <%@ page import="com.myapp.web.resources.ApplicationProperties;"%> <%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %> <%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %> <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %> <%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %> <%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %> <%@ taglib uri="/WEB-INF/struts/tld/struts-nested.tld" prefix="nested" %>
As soon as the jsp loads, NullPointerException is thrown as follows:2006-11-16 22:06:20,677 DEBUG [org.apache.catalina.loader.WebappClassLoader] Loading class from local repository 2006-11-16 22:06:20,677 INFO [STDOUT] ERROR [jsp].error:119 - Servlet.service() for servlet jsp threw exception java.lang.NullPointerException at org.jboss.portal.core.servlet.jsp.PortalJsp.service(PortalJsp.java:140) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:332) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:463) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:398) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:301) at org.apache.struts.action.RequestProcessor.doForward(RequestProcessor.java:1085) at org.apache.struts.action.RequestProcessor.processForwardConfig(RequestProcessor.java:398) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:241) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
Is this because the portlet tags will not work if the jsp contains other functionality tags?
However I noticed that when I remove PortalJSP & portlet taglib code, the jsp compiles without any error & also loads the contents.
Many Thanks in Advance,

theute Nov 16, 2006 1:21 PM (in response to girishramagiri)I don't know where you read that you had to extend PortalJSP, but please read the JSR-168 spec, il will help you a lot in portlet development.
You don't need to extend PortalJSP
