ode4j is a Java port of ODE.

ODE is an open source, high performance library for simulating rigid body dynamics. It is fully featured, stable, mature and platform independent with an easy to use C/C++ API. It has advanced joint types and integrated collision detection with friction. ODE is useful for simulating vehicles, objects in virtual reality environments and virtual creatures. It is currently used in many computer games, 3D authoring tools and simulation tools.

The latest released version of ode4j is 0.3.0, but the master branch contains numerous fixes and improvements. Version 0.2.4 up to 0.2.9 are ports of ODE 0.12.1, Version 0.3.0 is a port of ODE 0.13.1

ode4j contains also some features that are not present in ODE, such as a ragdoll and heightfields with holes. See Wiki.

The ODE forum is useful for questions around physics and general API usage:

The ode4j forum is for problems and functionality specific to ode4j/Java.
