I have two jsp files. The first jsp accept user input in form and then it calls the second jsp using Form action. And in the second JSP, it passes those two inputs to my Java Bean program, and then accept the output again from java bean and show the result using jstl.

In that case, I accept two inputs but it's opitonal. So, whether entering both two text boxes or either one of it is optional. The problem is say: if the user input in the first text box in the first time and then click the button. It will go to next page and show the result(what my java bean do). And then click the 'Back' button to go to the first page and in this time, if the user input only the second text box, but when passing the value, it also includes the value of the first text box which I have entered in first time.

It used to happen. So, I always have to restart Tomcat server and run the program again to avoid that problem. If not, it happnes like that.

So, how can I do my JSP not to keep the value input when I click 'Back' button.  Here's my two JSP prograsm.

Thanks!!
