X11 and Pure Java AWT

[Joel]

Hello everyone,
I'm trying to develop a servlet to produce graphs, and I can get it to work on my machine just fine. When I move the .class files over to our server, it crashes with the X11 error. I downloaded the PJA toolkit, and implemented it the way eteks said to, but I'm still coming up with the same error. Has anyone gotten this toolkit to work with JFreeChart yet?

Thanks in advance,
Joel

Thanks,
I actually got it to work just the other day. I got a different error (I can't remember how I fixed the first), where java couldn't find the eteks package at runtime. It would compile fine, but when java went to get the graphics environment, it couldn't find it anymore. So, in the end, and through much frustration, I unpacked rt.jar, stuck the eteks package in there, repacked it, and it works fine now 8^) Does anyone happen to know a better way of doing it than this, because this does work, it's just not a great solution.

It all depends. What server are you using?

Typically, you need to add the eteck.jar file to the classpath which probably means you need to modify a configuration file on the server.

Dino,
I haven't actually found out what server will be used when this goes into production (I'm finding out tomorrow morning.) As for testing, I'm using JBuilder's server on my own machine, and JSDK 2.1 web server for testing on a Unix machine.

As for the eteck.jar(actually pja.jar), I've got that sitting in my classpath, and it shows up as being in my classpath when the JSDK server starts. I looked in pja.jar, and the class that java says it can't find is in there. I also, just to test it, did an import of that class in my servlet, and it had no problems at compile time, so my compiler found it ok.

Which config file should I modify on the server? Also, what should I put in the config file. Sorry, I haven't done much webserver configuration before.

Thanks,
Joel
