hi,
the JVM uses the PermGenSpace to store the classes meta-information
(eg. needed for reflection). Current JVMs do not support gc of the
PermGenSpace.
Everytime Tapestry enhances a class (filling the abstract classes and
methods with life:)) a new class is generated and thus its
meta-information
get persisted into the PermGenSpace. This is true for any framework that
does class enhancements like Hibernate, ...
if your PermGenSpace keeps growing you might have Tapestry caching
deactivated. This means Tapestry is enhancing the page classes on
every action thus filling the PermGenSpace.
It is also possible another framework is causing the problem :)

What goes from Tapestry in Perm Gen Space? (Problem with tacos4-beta-2-lib
and tapestry 4.0.2)
Hi, I'm new to Tapestry.
I have an web application and I'm using Spring, Hibernate3 and it
works
with ajax using tacos4-beta-2-lib. My application uses one page and in
this
page many componentes are loaded with tacos. I have one ASO that contains
all.
My problem is that I looked to jvmstat via visualgc and the
PermGenSpace memory becomes greater almost to each action that I do in the
application. I serch about this problem on the internet and I found out
that
in PermGenSpace are store Classes and String.intern.
So my questions for the moment are:
What goes from Tapestry in Perm Gen Space?
Can gc clear the PermGenSpace?
On logout ?service=restart why PermGenSpace doesn't been
clear?
Please help!!!!!
Thanks in advance!
