Can’t comment on the demos but for compiling Jogl apps with JBuilder in general…
Since JBuilder uses an older JDK I suggest to use your system wide new JDK (1.4.2) for the following. Just copy the Jogl JAR and DLL into this main JDK (in its JRE directory):
Javasdk/Jre/bin/ : jogl.dll
Javasdk/Jre/lib/ext/ : jogl.jar
Then in your JBuilder menu “tools/config” do set the “config JDKs” to your above 1.4.2 JDK. That’s it. Compile and run Jogl appilcation from within JBuilder.
Of course running the application “manually” with the above JDK also works.
PS: If you don’t want to put the JAR and DLL to your JDK you still have to asure the DLL is known in the “java.library.path” (on Win32 this usually is “/.” plus your PATH system variable). Then in your JBuilder project’s properties enter a new “needed LIB” which points to the Jogl JAR file.
