Ben, Sorry. Yes I am using struts for my application, I posted it on the
JSP forum because I thought my problem had to do with a JSP page. Anyway thanks for letting me know, knowing that will let me get better and quicker answers next time, also it would me less work for you as well.
Beside, I found the solution to my problem, I try to solve it before posting it here, but once I am getting no where, I thought it was better to as.
I solve it by adding a single line to my code
<input type="hidden" name="param_name" value="box1" />
