First of all, you need a Struts proyect. I created a project with the following tutorial:http://netbeans.org/kb/docs/web/quickstart-webapps-struts.html.
Also, I uploaded this project at http://www.megaupload.com/?d=9EJND8KQ
Download the project.
Extract it.
Now, we have to create a new Portlet App with Eclipse.
Copy the libraries of WEB-INF/lib with the libraries of MyStrutsApp/build/web/WEB-INF/lib
Delete commons-logging-1.0.4.jar, standard-1.0.2 and jstl-1.0.2
You may download the tld files from:http://www.megaupload.com/?d=TFVCGMM2
Also, copy struts-config.xml,tiles-defs.xml,validation.xml,validator-rules.xml from MyStrutsApp/web/WEB-INF to WEB-INF/ of your Portlet Project
Next, copy the files index.jsp, login.jsp, success.jsp of /MyStrutsApp/web in Bridge-portlet/docroot
After that, copy the libraries jstl.jar and standard.jar to Bridge-portlet/docroot/WEB-INF/lib. The libraries are uploaded in:http://www.megaupload.com/?d=MWJ0BFRQ
And refresh your Eclipse project.
Next open liferay-plugin-package.properties. Click source. Replace the code with the following code:
name=Bridge
module-group-id=liferay
module-incremental-version=1
tags=
short-description=

Replace liferay-portlet.xml with the following code:
<?xml version="1.0"?>
<!DOCTYPE liferay-portlet-app PUBLIC "-//Liferay//DTD Portlet Application 6.0.0//EN" "http://www.liferay.com/dtd/liferay-portlet-app_6_0_0.dtd">

Change struts-config.xml to:

Next, change tiles-def.xml to:

Now, change the code of login.jsp to:

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

Next, change the code of success.jsp to:

After that, open the file loginAction.java. Set the following code:
/*

* and open the template in the editor.
*/
package com.myapp.struts;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
import org.apache.struts.action.ActionMessages;
/**

*/
public class LoginAction extends org.apache.struts.action.Action {
/* forward name="success" path="" */
private static final String SUCCESS = "success";
private final static String FAILURE = "failure";
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
// extract user data
LoginForm formBean = (LoginForm)form;
String name = formBean.getName();
String email = formBean.getEmail();
ActionMessages actionMessages = new ActionMessages();
actionMessages.add(ActionMessages.GLOBAL_MESSAGE,
new ActionMessage("errors.cancel"));
saveMessages(request, actionMessages);
// perform validation

formBean.setError();
return mapping.findForward(FAILURE);
}
request.setAttribute("title", "This is Test");
return mapping.findForward(SUCCESS);
}
}
Run the project.
The messages don't show in the screen. We have to replace the class MessageTag of apache. To replace the class, you have to create a new package(org.apache.struts.taglib.html) . Into the package create the class named MessagesTag with the following apache struts taglib code:
