It sounds like you have an unresolved dependency on Apache Commons Lang.

Thanks for the quick reply!

But there is one problem. I am a newbie to Struts and I am not able to figure out how to overcome this issue. Can you help me in this? I have posted my code already so you might get an idea as if what is going wronh there.

Thanks in Advance!

One thing you should do is remove your email, address and phone number from your signature. Unscrupulous people could use that information.
As for your problem, download the Apache Commons Lang library linked above and bundle it with your Struts application. Struts has many third-party dependencies so you may have to hunt down several more.
The struts distribution includes a "blank" application which contains all the dependencies and is a good starting point for building an application with struts. Have a look at it.
