I get a class not found exception:

Not sure this syncs with the backtrace you are getting, but make sure you follow Jan's instruction:

Copy a script (cf. assets/bird.rb) to /sdcard/jruby/processing.rb and run the app.

That was the final step I needed to get it running.

[pla1207]

nope, I've done that...how about porting to ruboto core? :D

[rscottm]

Make sure you haven't made any mods to the package name. That could cause something like this. I could post my build to see if that works for you. BTW, what are you running it on (emulator/phone, OS version).

If you want to try to make it work on ruboto-core, use the latest code and look at the similar 3D cube example: https://gist.github.com/723691

Or, I'll be releasing a new Ruboto IRB soon, and that should be able to run the cube example.

[pla1207]

reinstalled and now it works ! Thanks for your support

@pla1207: this was just a quick proof of concept, an integration it with ruboto-core is definitely on the cards.

Cool, thx a lot for it though..i wonder already how to do that because the activity stuff is wrapped somehow in the lib!?i'm unexperienced with android so sorry for my lack of competence..keep up the good work!!
