Apple has released Java 3D and the Java Advanced Imaging for Java 1.4.1 on Mac OS X 10.3 (a.k.a Panther).
R. Rawson-Tetley has posted SwingWT 0.76,
an open source, "100% pure Java library which very closely resembles the interface of Swing. The difference is that instead of using the Swing library, it drives native peer widgets from SWT" (the Eclipse GUI toolkit).
With this library, Java/Swing applications can be compiled natively under Linux using gcj. It also allows Swing apps to use native widgets.
This version adds support for disabled tabs in JClosableTabbedPane/JTabbedPane, thread safe method calls for all components, Scrollable JPanels in JScrollPane, a JTableHeader implementation, andJOptionPane.showinputDialog().
