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.
