Any one know what is wrong here? I have seen this error before with other java projects. What is the problem and the fix?

C:jme>java -Djava.library.path=./lib -cp ./lib/lwjgl.jar;./lib/jogg0.0.5.jar;.

/lib/jorbis-0.0.12.jar;./target/jme.jar;./target/jmetest.jar;./target/jmetest-data.jar jmetest.TutorialGuide.HelloAnimation

Class file version 48.0 is the class format for JDK1.4 (this means the second post here is not correct) - you are trying to run the application with an older java version (e.g. 1.3). -> Use a newer java executable. You can verify your java version by executing

java -version

This has to report at least version 1.4.
