The web.xml causing the error would be useful.

[Jay Shukla]

Thank David for reply.

Below is the web.xml.

[David Newton]

Do you have a properly indented one without the extra characters?

[Jay Shukla]

Hi David,

I removed the initial hyphen and made it indented it. But now i am getting below exception.

It does not have HelloAction.class file but i think IDE should automatically create it when i deploy an application

If my understanding is wrong then could you let me know how to compline that class separately as it contains other inbuild packages (e.g. com.opensymphony.xwork2.Action).

Thanks in Advance.

[David Newton]

There shouldn't be *any* hyphens.

If you're having an IDE issue then post a message in the IDE forum. I don't know if you have the package right, because I can't see your code. I don't know if your Eclipse is set up to compile and deploy properly.
