Re: Graphics (CEWOLF) using tomcat4.0.3
If you use Jdk1.4 your suppose to be able to use -Djava.awt.headless=true and supress the need for Xvfb or X server. I'm using tomcat 4.1.2 and jdk 1.4.0_03 and all i get is a HeadlessException. Any one with better luck out there? Carlos.

RE: Graphics (CEWOLF) using tomcat4.0.3
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. Oliver -Original Message- From: Iain Downie [mailto:[EMAIL PROTECTED]] Sent: February 4, 2003 06:16 To: Tomcat Users List Subject: 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.

It's a very annoying problem you're trying to solve - good luck. 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.

RE: Graphics (CEWOLF) using tomcat4.0.3
We use the xvfb to achieve that goal. (It's typically part of the linux distribution) With that it works quite transparently without any additional toolkit. The only thing we have to change in the tomcat installation is to set an env var DISPLAY that points to te virtual frame buffer. -Original Message- From: Iain Downie [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 04, 2003 12:16 PM To: Tomcat Users List Subject: Graphics (CEWOLF) using tomcat4.0.3 I face a problem rendering the images on Linux, which is what I really want.

Re: Graphics (CEWOLF) using tomcat4.0.3
We use the xvfb to achieve that goal. (It's typically part of the linux distribution) Yeh, I have read about this, but I did a 'find' for Xvfb on our RedHat 7.2 installation, and it didn't appear as an executable. As usual (being a bit of a Linux grunt) I could find no obvious documentation on the system to re-install or get it running. This would have been my favoured choice as it means not changing anything to do with Tomcat or Oracle App Server, however my ignorance made me look at alternativeshence the toolkit.

Re: Graphics (CEWOLF) using tomcat4.0.3
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.
