Could not start bundle org.glowvis ... Missing Constraint: Bundle Required Execution Environment: JavaSE-1.6

GLOW requires Java 6 (JRE 1.6). First install a new version of Java 6 on your system. Then, download a version of Protégé that does not include a Java VM. The full procedure is covered in the installation instructions.

UnsatisfiedLinkError: no nativewindow_jvm in java.library.path

If you receive this error, it means that the JOGL libraries (.dll or .so files) could not be found.

• Windows: Please install the JOGL installer, and reboot your system afterwards.
• Mac OS X, Unix: Please see Running GLOW on Unix for how to start Protégé properly.
