What's the best 3D graphics library for Java web apps?

I'm looking for a 3D graphics library for a Java web app. Could use some recommendations - only open source, though.

Edit: I don't really care how the graphics are output - Javascript/applets/canvas/flash but I want to write the graphics logic in Java.

From stackoverflow

• JMonkeyEngine is very good.

• Have a look at the The Lightweight Java Game Library. It provided developers access to crossplatform libraries such as openGl. And can run in the browser.

  Here are a few demos:
