Personal Java/Jeode/J2ME Personal Profile / Java App Launcher
« on: September 16, 2004, 10:56:44 am »
Greeting all.
This may not be interesting to anyone else but I like it:
I have several Java apps that I wrote for various reasons. I really find the whole IPK thing a major hassle as these are really just for me. I was content for a while to run my apps from the console (I wrote a bash script to list my classes and give me a choice) but it ocurred to me that it would be good to have a "launcher app" that I could put on the desktop that would read a text file (zlnch.txt) of otherwise stand-alone apps and luanch them. That way, any new app I write, I just copy the classes off to my CF card and edit the text file and I'm done. The apps need to have a argument-less constructor and basically do nothing in "main" but call the constructor.
So, anyway, if anyone is interested:
