Graphics (CEWOLF) using tomcat4.0.3
Deat List,
I'm trying to get charts embedded into my web applications using Tomcat
4.0.3 and JDK1.3.1. The graphing and servlet software is CEWOLF
(incorporating JFreeChart). I have no bother getting the charts to show on
Windows, but I face a problem rendering the images on Linux, which is what I
really want. I understand what the problems are, and need to install the
Pure Java AWT libraries.
However, I'm having a helluva time working out how to set Tomcat up so that
no matter what web application I run on Tomcat, these libraries will be
available.
Has anyone else ever used the PJA Toolkit (http://www.eteks.com/pja/en)?
Would really appreciate some help configuring.
Iain

Hello friends,

When I press login button on login.jsp page to enter to another page I

Could you help me?

Iain, a quick question . . . .
Are you running an X Server on your Linux machine? If
not, you'll either need to upgrade to jdk 1.4.x or run
a virtual frame buffer in order to use graphics.
HTH
/mde/
just my two cents . . . .

Thanks Oliver
I run tomcat4.0.3 on a linux development server on-site, so I know I could
migrate to jdk1.4.1 and everything would work quite easily. However, our
live server runs Oracle App Server, and upgrading that (for either PJA or
JDK1.4.1) is a bit of a black box, so I'm trying to work out the best
solution. Knowing how to install PJA in the first place would be a help in
making decisions. I may just have to grin and investigate upgrading the jdk
on both servers.
Cheers
Iain

Not sure if it's relevant to you, but if you move to JDK1.4.1 you can run
headless, which means the JFreeChart libraries won't try to call the X11
libraries for drawing (which seems to be what you're trying to get around
with the PJA). It's a very annoying problem you're trying to solve - good
luck.
