The Gnu Project has released version 0.13 of
GNU Classpath, an incomplete
free implementation of the
core Java class libraries. This release fills in numerous holes in support across the core libraries including
HTTP/1.1 and FTP URL handlers and much better XML support
including JAXP 1.3 (see the related item on Cafe con Leche) and java.beans.XMLEncoder and
java.beans.XMLDecoder classes.
This release also improves
AWT and Swing support, especially on gtk+.
There's also an experimental Graphics2D implementation (not turned on by default).
Since this is a clean room project, it doesn't always line up exactly with any particular Java version. This release is a complete implementation of the Java 1.0 API, aside from a few places where the 1.0 and 1.4 API conflict,
and implements most
classes and methods added from 1.1 through 1.4.
GNU Classpath is published under the GPL with library exception.
