Hi, I am running Windows XP with Eclipse and JME Physics 2.1
I get the folowing error when trying to run some code:

I think it's trying to get some function from the native, I am using odejava.dll that comes with the latest stable release of odejava, JME Physics 2.1 does not include any dll file. Where can I get the right one?
Thanks.
Both jME Physics 2.1 release, as well as the CVS version include a odejava.dll.
Your error message complains about a missing log4j.jar not about a native file.
Sorry to bother you, I got log4j.jar and now I get this error message:

what I am missing?
Now it's your natives 
- take the odejava.dll from jME Physics or odejava-jni your version is too old.
