Working with portlet container in websphere application server 7.0-Part2

I have developed Sample portlet and deployed the portlet in WAS 7.0.

My context root of  this application is /myportlet.

I am able at access the  application URL

https://localhost:10002/myportlet/MyPortlet

Here MyPortlet is portlet name.

Sample Code

MyPortlet.java

package com.ibm.myportlet;

import java.io.*;
import java.util.*;
import javax.portlet.*;

/**
 * A sample portlet based on GenericPortlet
 */
public class MyPortlet extends GenericPortlet {

    public static final String JSP_FOLDER    = "/_MyPortlet/jsp/";    // JSP folder name

    public static final String VIEW_JSP      = "MyPortletView";         // JSP file name to be rendered on the view mode
    /**
     * @see javax.portlet.Portlet#init()
     */
    public void init() throws PortletException{
        super.init();
    }

    /**
     * Serve up the <code>view</code> mode.
     *
     * @see javax.portlet.GenericPortlet#doView(javax.portlet.RenderRequest, javax.portlet.RenderResponse)
     */
    public void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException {
        // Set the MIME type for the render response
        response.setContentType(request.getResponseContentType());

        // Invoke the JSP to render
        PortletRequestDispatcher rd = getPortletContext().getRequestDispatcher(getJspFilePath(request, VIEW_JSP));
        rd.include(request,response);
    }

    /**
     * Process an action request.
     *
     * @see javax.portlet.Portlet#processAction(javax.portlet.ActionRequest, javax.portlet.ActionResponse)
     */
    public void processAction(ActionRequest request, ActionResponse response) throws PortletException, java.io.IOException {
        System.out.println("calling process action");
        response.setRenderParameter("myname", request.getParameter("myname"));
    }

    /**
     * Returns JSP file path.
     *
     * @param request Render request
     * @param jspFile JSP file name
     * @return JSP file path
     */
    private static String getJspFilePath(RenderRequest request, String jspFile) {
        String markup = request.getProperty("wps.markup");
        if( markup == null )
            markup = getMarkup(request.getResponseContentType());
        return JSP_FOLDER + markup + "/" + jspFile + "." + getJspExtension(markup);
    }

    /**
     * Convert MIME type to markup name.
     *
     * @param contentType MIME type
     * @return Markup name
     */
    private static String getMarkup(String contentType) {
        if( "text/vnd.wap.wml".equals(contentType) )
            return "wml";
        else
            return "html";
    }

    /**
     * Returns the file extension for the JSP file
     *
     * @param markupName Markup name
     * @return JSP extension
     */
    private static String getJspExtension(String markupName) {
        return "jsp";
    }

}
