We've been down for the count for 57 hours
Litha-Paint.com is online again after a massive knock-out. We apologies for such a long interruption. During the technical investigation of the server's crash we've learned a several simple lessons:
1. Never use Sun's JDK 1.5 on Red Hat 7.2.
At the first time, tomcat has been working fine for a week. But then the server hanged. Even sshd did not work. Only hard reboot did help. It seems like RH 7.2 is too old for J5.
2. It is not easy to use even jdk 1.4 on Red Hat 7.2 without X11.
AWT subsystem uses X11 server which is absent on our RH 7.2 installation. It is not enough to only run "/usr/X11R6/bin/Xvfb :0 -screen 0 1024x768x32 &" (see http://www.pokerapp.com/xvfb.html and http://www.idevelopment.info). In addition to that you must use "-Djava.awt.headless=true" option for java (see http://groups.yahoo.com).
3. Study release notes more thoroughly.
Before deciding what platform you want just be sure that your software works well on it. Quite simple, isn't it? :-)
We are happy that you are with us.

that's the problem with java, when a server goes down without a shadow server you are dommed.
I prefer using scripting languages for that reason, backend stuff like agents I prefer C++.
Nice work on the litha-paint, I've been thinking about doing something like this for 1.5 year in a half basically but I want to add into something else I'm developing. Now I finally found the last pieces of the puzzle for the javascript part so I can do the xslt parsing on multi-browsers.
Best,
