Harish,

Ideally controller will be unique for MVC structure i think. So you can definitely call different methods from different classes in controller class it self and can achieve your requirement.
Or else you can use struts portlet which can call different action classes as per the struts action URL.

A portlet can have only one portlet class which you have configured in portlet.xml. Based on your RENDER or ACTION URL, you process or render action will be triggered .

ACTIONURL
=========
 1<liferay-portlet:actionURL name="addMethod"></liferay-portlet:actionURL> , this url will trigger you action method from your portlet class....
 2
 3public class TestPortlet extends MVCPortlet {
 4
 5public void addMethod(ActionRequest actionRequest,
 6            ActionResponse actionResponse) throws IOException, PortletException {
 7      // logic goes here
 8}
 9}

Like that, you can have "N" number action method in your portlet class.

RENDERURL:
===========

1<liferay-portlet:renderURL var="testRenderURL">
2    <liferay-portlet:param name="jspPage" value="/html/portlet/test/test.jsp"/>
3</liferay-portlet:renderURL>
4
5<a href="<%=testRenderURL.toString()%>" /> Go to test page </a>


if you mention "jspPage" parameter with your render URL, it will directly go to that particular jsp file through doView/render method of your portlet class.

if you dont mention "jspPage" parameter with renderURL, then you have to redirect to jsp file from doView/render method .

Sorry for interupting the post.
I have a similar query.

I have my portlet class in package com.test.portal. I have included two more classes in it, say a.java and b.java just to make my code clean by including similar functions in one class.

How should I access the functions from a.java or b.java since whenver we specify action in form, it goes to the Action class?
