<p>
GNU Classpath is a set of essential libraries for supporting the Java
language. Our goal is to provide a free replacement for Sun's
proprietary class libraries so that the GNU system can run programs
written in the Java language.
</p>
<p>
Classpath is licensed under the terms of the <link url="/copyleft/gpl.html"
name="GNU General Public License"> with the following special exception.
</p>
<p>
<blockquote>
<code>
As a special exception, the copyright holders of this library give you
permission to link this library with independent modules to produce an
executable, regardless of the license terms of these independent
modules, and to copy and distribute the resulting executable under
terms of your choice, provided that you also meet, for each linked
independent module, the terms and conditions of the license of that
module. An independent module is a module which is not derived from
or based on this library. If you modify this library, you may extend
this exception to your version of the library, but you are not
obligated to do so. If you do not wish to do so, delete this
exception statement from your version.
</code>
</blockquote>
</p>
<p>
As such, it can be used to run free as well as proprietary
applications and applets. Using GNU Classpath as the class library
for a Java virtual machine (JVM) does not affect the licensing of the
JVM.
</p>
<p>
Classpath is still a work in progress. The first public release will
be version 1.0. There have been no public releases; however, pre-release
source code is available via GNU's anonymous
<link url="http://savannah.gnu.org/cvs/?group_id=85" name="CVS server">
, and snapshots of the Classpath tree have been released and are
available from <link url="ftp://alpha.gnu.org/gnu/classpath/"
name="ftp://alpha.gnu.org/gnu/classpath/">.

GNU Classpath 1.0 will be fully compatible with Java 1.1 and largely
compatible with Java 2. Detailed information on the
current state of a package can be obtained by clicking on the
appropriate link below. This information will become part of the Savannah
Tasks information in the future and no longer appear on this page.

The test framework for GNU Classpath is called
<link url="http://sources.redhat.com/mauve/" name="Mauve">. There
are instructions within the Mauve website on how to download and use Mauve.

The primary target for GNU Classpath was originally <link
url="http://www.japhar.org/" name="Japhar">. Japhar-0.07 works out-of-the-box with
GNU Classpath-0.00. Japhar-0.09 is required for newer releases of GNU
Classpath. In the past couple of years no one has been able to take
over the maintenance of Japhar and once again Japhar does not work
with GNU Classpath CVS. Thankfully other VMs have taken an
interest in GNU Classpath and those are listed below.

Although GNU Classpath cannot be compiled for use with
GCJ at this time, a lot of work has been done to merge GCJ class
library code and GNU Classpath class library code. This has resulted
in a better version of each. The current merge status between the two
projects is <link url="http://gcc.gnu.org/java/libgcj-classpath-compare.html"
name="located here">.

Information about ORP
can also be found at <link url="http://orp.sourceforge.net/"
name="http://orp.sourceforge.net/">. We're hopeful that the next
version of ORP after 1.0.6 will allow users to optionally use GNU
Classpath native libraries instead of those bundled with ORP. ORP is
the easiest VM to test GNU Classpath with including JNI native libraries
but you must patch ORP to do so. Information is available in the
mailing list archives.

The Aegis VM Project is an on-going effort to develop a lightweight,
secure virtual machine for executing Java bytecode. The Aegis VM will
eventually feature a modular bytecode verification architecture that
allows user-defined static verification procedures to be integrated
into the VM's dynamic linking process through pluggable verification
modules.
