First off, I am very sorry I'm sure this may have been answered before, but I did a lot of searching and couldn't find something applicable to my situation. Basically, I used this tutorial to set up eclipse to allow me to work/debug a processing application. Everything is going really great, but I forgot, d'oh! I'll want to export this at some point. Well, the bad thing is, I can't! When I try exporting as a jar and then running said jar I get this error:

no main manifest attribute, in C:\test.jar

Can someone throw me a bone and point me in the right direction?
