I have added below jar files in my classpath:

struts2-core-2.3.4.1.jar
commons-beanutils-1.8.0.jar
commons-chain-1.2.jar
commons-collections-3.1.jar

javassist-3.11.0.GA.jar
ognl-3.0.5.jar

web.xml:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
    </filter-class>
</filter>

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

I have followed this thread but no success.

Kindly help.

You've added the jars to *what* classpath? If they're not *deployed* with your S2 app, it doesn't matter what classpath they've been added to. — Dave Newton, Sep 01 '12 at 17:50
@UmeshAwasthi: I have added the full server log.. hope this helps. — DarkKnightFan, Sep 01 '12 at 18:57
@DaveNewton: I have added the jars to the classpath of the application. — DarkKnightFan, Sep 01 '12 at 18:58
@Gaurav Meaning what? Please, please be specific. Where are the jars when they're deployed? How are you deploying? What makes you think they're in the right place? It doesn't seem as though they are. — Dave Newton, Sep 01 '12 at 22:18
@Quaternion: I am using Eclipse Europa. Simple reason, I am comfortable using eclipse for my development. I have created a dynamic web project in that and deployed the app on tomcat v6.0 — DarkKnightFan, Sep 02 '12 at 08:59
@DaveNewton I have added the screenshot of my application buildpath screen. I have added them as external jars in to my project. I am adding the project into the tomcat 6.0 server. On restarting the server I am getting the error log mentioned above. — DarkKnightFan, Sep 02 '12 at 09:06
The build path doesn't matter, uuuu need to make sure the libraries are being deployed. I can't see the picture on my mobile device anyway. — Dave Newton, Sep 02 '12 at 11:47
@Gaurav I was asking about the IDE because it could help us provide you with step by step instructions. Maven is method of build which handles a lot of the dependency management. Think of it as another project type managed by your IDE. I'm not familiar with your IDE so will not be able to help but someone else may. — Quaternion, Sep 02 '12 at 17:50
@Gaurav: if problem is still there i suggest you to clean your work directory and uninstall app from server and clean tomcat work-directory and rebuild your app and try to deploy it and see how it is going and alternatively export your app as war and deploy it in independent tomcat to see how it goes and have a look at the directory structure under tomcat web-app — Umesh Awasthi, Sep 03 '12 at 03:02

It's weird. You have all jars, but you can try with this web.xml to use version 2.4. I'm using netbeans with tomcat 7.

<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <filter>
    <filter-name>struts2</filter-name>
    <filter-class>
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
    </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping> </web-app>

However you can see the apache log to find the exact problem like below:

Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang3.StringUtils
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1711)
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1556)
