Please be informed that NONE of the design/code from this
page is claiming to be some sort of best practices and we DO NOT expect
any of our visitor/reader of this page to assume this as some sort of
best practice for any context and should not be using this 
as it is without appropriate evaluation to their, so to say, 
specific programming context.

This page intends only to provide bit and piece of known ways  for
doing some sort of example and may not be fit for any other purpose.

Integrating JSF with Struts2 example code: In this example I shall try to demonstrate a simple way and may be one out of many ways of integrating JSF with Struts2, using Plugin available with Struts2 Framework. In this example, I shall be working on ways to achive page and action navigation flow using Struts2 and displaying target JSF page using JSF UI component. So the index JSP page will have form and action Tags from Struts2 Tag Library, and the next preview page will be using JSF Tags from TagLibrary. index.jsp

<%@ taglib uri="/struts-tags" prefix="struts2"%>
<html>
<head>
</head>
<body>
<struts2:form method="post" action="jsf-view" namespace="/sample-jsf">
<table>
<tr><td><struts2:textfield key="userName" label="Name :"/></td></tr>
<tr><td><struts2:textfield key="roll" label="Roll :"/></td></tr>
<tr><td colspan="2"><struts2:submit value="Register"/></td></tr>
</table>
</struts2:form>
</body>
</html>

Looking at this index.jsp file, I can say the Register button submit action points to "jsf-view" with namespace as "/sample-jsf" and the two text fields as userName and roll. Now the struts.xml file will be having the mapping for this action and the Action class along with the configuration for defining JSF related interceptors for using JSF mapping as the result for success from the Action class file action method. struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <package name="jsf-example" namespace="/sample-jsf"
                 extends="jsf-default">
        <action name="jsf-view" class="sample.ExampleJSFAction" 
	                       method="preview">
          <interceptor-ref name="basicStack"/>
          <interceptor-ref name="jsfStack"/>
            <result name="success" type="jsf">
              <param name="location">/preview.jsf</param>
            </result>
            <result name="input">/index.jsp</result>
        </action>
    </package>
</struts>

In order to use JSF related Tags in the preview.jsp file, we have to define these interceptor-ref tags as mentioned in bold as shown above. The Action class has two variables with same name as those defined in the index.jsp file (userName, roll). sample.ExampleJSFAction.java

package sample;
public class ExampleJSFAction
{
    private String userName;
	private String roll;
	public ExampleJSFAction() {
	}
	public void setUserName(String arg) {
       userName = arg;
	}
	public String getUserName() {
		return userName;
	}
	public void setRoll(String arg) {
		roll = arg;
	}
    public String getRoll() {
		return roll;
	}

	public String preview() {
		System.out.println(userName+"   "+roll);
		return "success";
	}
}

the finsl preview JSP file is having JSF tags defined and the dynamic values to this Page is comming from the Struts2 Action Object. preview.jsp

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="sampleHtml" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="sampleCore" %>
<html>
<body>
<h4>Preview</h4>
<sampleCore:view>
  <sampleHtml:form>
    <table>
     <tr><td>Name :</td><td><sampleHtml:outputText
                     value="#{action.userName}"/></td></tr>
     <tr><td>Roll :</td><td><sampleHtml:outputText  
                     value="#{action.roll}"/></td></tr>
    </table>
  </sampleHtml:form>
</sampleCore:view>
</body>
</html>

Software environment I have used to test this example is as follows: 1. JDK 1.5.x 2. Eclipse 3.2 3. Struts 2.1.6 4. JSF 1.0 specification API and Impl. 5. Jakarta Tomcat 6.0.18 And I have used following set of Jar files in the WEB-INF/lib folder, in irder to run and test this example, and this works well in my local software environment.
