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?
