Hi All,

I am new to struts, i am practicing using some examples. I was struck with a program. Please help me where i am wrong. I am pasting all the files here.

On Tomcat console i am able to see only one statement from the ActionForm. Later the control is not going to Action class. Can any body help me to solving this?

<h1>
<form action='welcome.do' method='post'>
Enter your name:

Hey Anand,

Thank you for your reply. I modified the package name but still problem exists like that only. I am able to see only one output on console 'in set'.

It is not at all entering Action class. Please help, i am running out of thoughts

I personally made a new project and tested the code. It works all fine.
Probably you are missing something somewhere. Well, it's really difficult to comment.
But, please specify the steps that you took to make the project. You have got on some other boat somewhere.
