my 3D app currently have no Anti-Aliasing, however when i go to my graphics card control panel i can force a certain level of Anti-Aliasing for all 3d aplications. This works perfectly fine for my 3d app but i dont want to change stuff in my graphics card settings for my app to work like i want it to. instead how can i force on Anti-Aliasing in my program itself i have a ATI card and i use java with the jogl wrapper (dont think this makes any difference though)

This is off the top of my head, so I'm not sure how correct it is:

glHint( GL_POLYGON_SMOOTH_HINT, GL_NICEST );//optional, tell it to use it's best AA algorithmglEnable(GL_POLYGON_SMOOTH); //turn on AA

it doesnt have any effect

not on my app at least.. maybe jogl has issues with AA

That will enable local anti-aliasing, which is rather slow compared to actual FSAA (Full Screen Anti-Aliasing) and this, I believe, is actually what the OP wants, since controlling AA from the CCC is mentioned.
Although I cannot remember how to enable FSAA with JOGL, I can tell you that it is usually applied/requested when creating the OpenGL context, since FSAA requires multiple extra frame-buffers for the sampling.

Are you using Windows?
If so, you have to turn on Multisampling for your app.

This is a tutorial at NeHe

ive already tried that code.. i dont know how to get that from c++ to java and there isnt a java port for it alerady which led me to believe that that way wont work with jogl at all

Simple google search of "Multisample Jogl" lead to this
