Hi Nikolay,
That's correct, the "out" variable generated by the JspWriter is not the
same as the one which is generated for the JSP fragments within the "new
ActionListener() {...}" definition. And the error simply says that the
JspWriter's "out" method is not final and hence not accessible to the inner
class defined with "new ActionListener() {...}".
Could you not use something as below:-
button.addActionLister(
new ActionListener() {
// code here
PrintWriter outPW response.getWriter();
boolean res=function();
if (res) {
outPW.print("TRUE");
}
else {
outPW.print("FALSE"
}
}
);
HTH,
Dharmendra
ps: have a good day!

Subject: JSP with JFrame
Hello Everyone,
I'm developing a JSP page and can not do the following thing:
The JSP page should lunch 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. Any suggestions
would be great.
