You have a lot of problems with your dependencies.  See our FAQ entry here.  
Note that the Struts2 and Xwork JAR files must be the same version number, as they are released in a synchronized manner.  You should also update Struts to the latest version as there are security issues with older versions.

Thanks for the information Joe. But still I'm facing issues, I'm trying to integrate with Sruts2 with Tiles. I have added the jar files that you mentioned previously and also added some new jar files(added as a resolution for some issues). But I'm getting exception after resolving each issue.I have used 'struts2-tiles-plugin-2.2.3.1.jar' in my application. Could you please help me on this.

At the moment I'm getting below exception,

SEVERE: Exception starting filter struts2

In my investigation i came to know that servlet-api.jar that is part of lib folder causing the problem, removed that and tried but no luck.

also found below exception also in console,

"javax.servlet-api-3.1.0.jar - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/servlet/Servlet.class".

Yes, the servlet api JAR is not needed as that should be provided by your servlet container.  Are you using maven?  If so, you will have to explicitly exclude that dependency.
If you are still having issues, we need to see the complete stack trace of the error.  Usually what happens is there will be one exception that is caused by another (and possibly more), the last one being the root cause of the issue.  The root cause is usually a missing dependency.

No I'm not using maven. I have added all library to lib folder. Still I'm facing same exception:

Please see the below full stack trace:-

Please do not post the same question more than once.  It causes confusion and duplication of effort as the community tries to help everyone.
Did you happen to set the StrutsTilesListener up in the web.xml as a filter? Obviously that will not work.  See here for the correct configuration.

Apologies for the repeation. Here is my web.xml,

<listener>
<listener-class>
org.apache.struts2.tiles.StrutsTilesListener
</listener-class>
</listener>

<context-param>
<param-name>org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name>
<param-value>/WEB-INF/tiles.xml</param-value>
</context-param>

<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>
<welcome-file-list>
<welcome-file>BaseLayout.jsp</welcome-file>
</welcome-file-list>

I'm not understanding when  resolving one issue, I'm getting another issue back to back.Is it due to the jar versions are not compatible? Now I'm getting below error message,

Joe, Please review the Jar file used(Image format) and  is it good to go-ahead with this combination. Please throw your view?

Many thanks,

Your best bet is to check your Struts distribution, like the FAQ I linked you to earlier describes.

Deep in your exception stack, you will see this line:


It looks like there's an error in your Tiles configuration file.
