Hello Everyone,
PROBLEM DESCRIPTION: I'm developing a JSP page which lunches a JFrame
(basically it's a panel with a button). There is a listener to the
button and when the user click it, it calls a boolean function. And I
want depending on the returned result from this function to show
different JSP pages.
-------------------------------------------------------------------------
MY APPROACH: So here is what I've done:
In my JSP page, i've added the listener to the button (
button.addActionLister( new ActionListener() {
// code here;
boolean res=function();
if (res) { %> OK <% }
else { %> FALSE <% }
} );
But when run this JSP on Tomcat, it gives the error:
Cannot refer to a non-final variable out inside an inner class defined
in a different method
The problem here is that, The JSP is converted into Serlet which
contains the non-final variable "out" from type JspWriter and I cannot
access it. I've changed it to final in the created servlet and then
recompiled it, but somehow It doesn't work and I don't know what to
do.
Maybe my approach is too difficult or I don't know.
