.jar help
So, in the process of learning Java, I'm working through Intro to Programming Using Java, I've been assigned a project. The goal is to take a fully functioning desktop application (a 3D fly through) and turn it into an applet. I received the code and started in today.
Here's where it gets ugly. I really have no sense .jar files. I know what they do and what they're there for, but have no idea how to handle them. The application has two particular ones that need to be implemented, gluegen-rt.jar and jogl.jar. I cannot get the program to run (as it does on other's computers) on mine and I know I'm not installing, extracting, classbuilding, etc. these libraries (.jars) in the right way for the program to use them at runtime.
I'm currently using Eclipse SDK on Windows XP. Is there an idiot's guide for placing .jar files properly? I seem to remember my higher-ups saying I needed to download a jogl distribution and make changes to a Windows .DLL for all of this to function. The people above my aren't really available for regular assistance, so anything I could get here would be tremendously appreciated.
