Harmony Java Development Kit
This is a snapshot build of the Apache Harmony JDK for Java SE 5. This software is not complete or verified as compatible with the specification.
This snapshot contains the the current state of our JDK, including the JDK tools that we have completed in jdk/bin as well as the current state of our Java Run-time Environment (JRE) in the jre/ subdirectory. The JRE is the runtime environment needed to run Java programs, consisting of the Java class libraries and a virtual machine, DRLVM.
For information on supported platforms and completeness of the supplied software see the file status.html in the doc/ subdirectory.
To use the Harmony JDK, you should be able to unpack the distribution, add jdk/bin to your patch, and run the software. For more information, follow the instructions in the file quickhelp_users.html in the doc/ subdirectory. For the most up-to-date information on using this package, please see
