Hello,

I am trying to run a simple portlet having a jsp but gettting the error org.jboss.portal.portlet.container.PortletInitializationException.

The jsp contains a text area and a button to invoke the portlet's processAction method.

The jsp looks like: spellcheckPortlet.jsp
--------------------------------------------------------------------------------------
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>

<portlet:defineObjects/>


This is sample Spell Check Portlet.
Please Enter text for Spell Check in the text area below.

<form action="<portlet:actionURL><portlet:param name="page"

value="mainview"/></portlet:actionURL>"
method="POST">
Name:



You can also link to other pages, using a renderURL, like <a
href="<portlet:renderURL><portlet:param name="spellCheckText" value="Enter the text for

Spell Check."></portlet:param></portlet:renderURL>">this.
