Hi all,
I was debugging my sessions size in order to reduce it and I saw that one of
my page spend 20ko because of an dynamic image generated with JFreeChart.
JFreeChart was serialized with my DynamicImageRessource.
My first optimisation is to make JFreeChart a static field initialized in a
Then this image will to be the same for all sessions. If you don't want that
object on your session, make sure at getImageData method implementation that
you are always creating your chart object, and not keeping it in any
instance variable.

In fact, I just put the reference to JFreeChart as static. All the commons
values are initialized in the static bloc (ie, Font, definition on the axis,
...).
I keep the image generation done in the getImageData using the
pageParameters. So every session or even page request can have its own

You can mark whatever instance that is causing the session to be so large as
'transient' to avoid it being serialized -- you'd have to recreate it each
time it was needed though. So if it's in your model:
=
private String chartName;
private String chartArguments; // maybe
