java-gnome

java-gnome is a set of language bindings for the Java programming language for use in the GNOME desktop environment. It is part of the official GNOME language bindings suite and provides a set of libraries allowing developers to write computer programs for GNOME using the Java programming language and the GTK+ cross-platform widget toolkit.

Up until version 2.0, java-gnome was written by a project team,^[2] the current version 4.0 was originally an internal project of Operational Dynamics, a change management consultancy group.^[3] This new version is a complete re-write of java-gnome and was originally written for creating business tools to the company's clients, but eventually grew into a full replacement Java language binding for GNOME.

Unlike most other GTK+ bindings, there is no version available for Microsoft Windows.

Java-gnome is free software released under the terms of the GNU General Public License.^[4]

Example

To compile a java-gnome class it's necessary to add the gtk-4.1.jar jar in the classpath. The jar is available on Debian (and all Debian-based distributions) in the libjava-gnome-java^[5] package, which can be found in the official repositories (the jar is installed under the /usr/share/java path).
