You might want to read up on how the Java classpath works, just so you're not trying stuff at random :) It's often confusing to newcomers, and it took me a while to fully understand.

There are lots of different ways to set up your source and class directories. Here's how I'd normally lay out the directory tree for your project:

test
    jar
        gluegen-rt.jar
        gluegen-rt-natives-*.jar (one file per target OS)
        jogl-all.jar
        jogl-all-natives-*.jar (one file per target OS)
    src
        joglDemo
            OneTriangle.java
            OneTriangleSwingGLJPanel.java
    class
        joglDemo
            OneTriangle.class
            OneTriangleSwingGLJPanel.class
            OneTriangleSwingGLJPanel$1.class
            OneTriangleSwingGLJPanel$2.class

Then I'd cd into the test directory and type "java -classpath "jar/gluegen-rt.jar:jar/jogl-all.jar:class" joglDemo.OneTriangleSwingGLJPanel", and it should run.

Don't worry about the OneTriangleSwingGLJPanel$1.class and OneTriangleSwingGLJPanel$2.class files. The compiler generates those for the anonymous inner classes "new GLEventListener() {...}" and "new WindowAdapter() {...}" inside of OneTriangleSwingGLJPanel.java. Those extra class files are normal, and are needed to run the program.
