JXUL is an open-source project to implement the XUL user interface framework from Mozilla in Java.

The project intends to allow XUL-based user interface definitions to be imported and used in Java applications, giving them the benefit of XUL's ability to quickly create reusable UI components. One of the project's goals is to support a subset of XUL in KVM, the Java virtual machine for the Palm Pilot.

JXUL has already had some development work and downloadable binaries and source are available from the project web site.
