I've recently downloaded all the code from cfish's site and even decompiled it. (I had a hard time until there since I'm a total java newbe. In fact I didn't even know what a jar file is) It's working fine on my PC currently. I also looked a bit at the code. It seems like cfish stored the db files sent by the users on a php-server somewhere else so he could repack his application from time to time to keep the data up to date. I was wandering if anybody might be interested on relaunching CMT. I attached the cmt.jar-file (unrar it first, then unzip/unjar; I used WinRAR to do that), which you can just unzip to get the original *.class-files and the decompiled files I gathered with DJ Java Decompiler.
