Hi all,

I really hope that You are able to help me.
I am programming an application, which is something like image gallery.
So I need handle with images. But because the application is to be run
on an server with very restrictive security policy, I am not allowed to
set properties like "awt.toolkit", "com.eteks.awt.PJAToolkit".
So the application still requires libawt...

My question : Is it possible to use the PJA classes without setting these
properties????

Thanks in advance

Jenda

You may run PJA without setting System properties if you use directly PJA classes like PJAImage (a subclass of java.awt.Image), PJAGraphics (a subclass of java.awt.Graphics) and PJAGraphicsManager (a class that looks like java.awt.Toolkit but that is able to run with a restrictive security policy).
For more information, please read the FAQ "What methods can be called in a servlet with no problem of Toolkit access for end users ?" provided in the index.html file of PJA download, and read these two subjects :
