Hi all,
I am having two select boxes in my jsp page. I need to populate second select box depending upon the value selected in first select box. I am able to do this. But the problem is i am not getting the value selected in the second select box in the action class. i have provided getters and setters for both select boxes.

Looking forward to hear from you..

regards,
sunitha
