[Solved] Java not finding native "bulletjme" at runtime

Troubleshooting physics

The sample code from Starting a JME3 application from the command line compiles fine, but when I try to run it, java can’t seem to find “bulletjme”. Wanted to see if someone could point me in the right direction. I’m on linux x86_64 and I’ve tried it with java 8 and java 11. Thanks.

JME has two implementations of Bullet: the official native bullet library, and the jBullet Java port. Both are accessed via the classes in jme3-bullet.jar, but you still need one of the implementation jars in your classpath - either jme3-bullet-native.jar or jme3-jbullet.jar.

Thank you so much for the quick reply. That fixed it. Now it’s not finding some other library. I’m going to mess with it a while. Thanks again.

I’m replying to myself in case someone else has the same issues.
I ended up having to add “jme3-bullet-native.jar” and “gson.jar” to the classpath to get the example to run.
