NetBeans and Junit?

Hey everyone,

  I am new to JME, and so far I love it! I am trying to build and compile the open source game air carrier. I am using netbeans 5.51 and jre 1.6. When I try to compile it, the compiler cannot find the junit import files, such as: import org.junit.Test;, import org.junit.Before;, etc… The compiler could also not find: com.jmex.audio.AudioSystemException;. How can i setup junit with netbeans and where can i fix that other missing file? Thanks!

The junit jar is in jme/lib  (junit-4.1.jar)  What's asking for com.jmex.audio.AudioSystemException?
