I am currently porting the KAT to OSGi in order to get a more sphisticated runtime environment that is separated from the user interface. The reason is that we also want to develop a web version of Semaplorer. However, I had some problem with running the current GUI within OSGi. The reason was that the Substance classes could not be located and I got a bunch of exceptions like the following:
UIDefaults.getUI() failed: no ComponentUI class for: javax.swing.JButton[...
Some searching around the web lead me to the following solution:
UIManager.setLookAndFeel(new SubstanceBusinessBlackSteelLookAndFeel()); UIManager.getLookAndFeelDefaults().put("ClassLoader", SubstanceLoader.class.getClassLoader());
