Can't compile jme projects

Troubleshooting General Help

jme worked for a while, but for some reason I started getting this error when I try to run a jme program:


init:
deps-jar:
compile:
run:

Additional Info:

I just updated jme-physics, could that have anything to do with it?
2

Try updating jME from CVS.

3

Still not working.  :frowning:

4

is the build file in the correct directory - look at the build.xml and ensure that the paths it uses are available from the directory of the build file

5

sorry, i'm a newb.  can you explain that in simpler terms?

6

suggest delete all files that you have brought from cvs and get them again.

7

The error you are getting is related to the java VM not finding the JAR files for jME. In particular check the settings of your IDE, and the main project in your application.

OK, reinstalling jme from scratch worked, but I'm getting an error when I try to run a physics app:

You're still missing jars.



I don't use physics so I can't say exactly which but it's probably something like odejava.jar.  Basically make sure you've added all the jars you get with jME-Physics2 to the classpath as well as all the jME ones.

10

yeah, there is an odejava.jar somewhere down the imp/odejaval - directory

(and a native lib too)

11

I just reinstalled jme from scratch according to the instructions.  These are the classpaths:

-Djava.library.path="/home/noah/cvs/jme/lib":"/home/noah/cvs/jmephysics/impl/ode/lib"

In /home/noah/cvs/jmephysics/impl/ode/lib there is a odejava.dll and an odejava-jni.jar.
12

No that’s the native library path not the classpath.



You are missing jars from the Java classpath.
