Acknowledgments
====================================================================
Special thanks to all of the community members who have contributed
ideas, reported problems, provided patches, and have helped greatly to
improve the quality, and robustness of this release.

Particularly for this release(in alphabetic order):

- Eric Xu <[email protected]>: You will find ericx has reported quite a
few bugs
   and those are very good findings. With his contribution, we have made
JXTA-C
   more mature and robust.
- Mathieu Jan <[email protected]>: Benchmark and improvement on latency
   issues.
- Mike Duigou <[email protected]>: RendezVouse server capability.
- Rick Keiner <[email protected]>: Rick contributed a SQL-based CM
   which enables wildcard search. He also contributed XPath query.
   These bring the search capability in JXTA-C to a different level to
   other platforms. :-)
- Stefan Lankes <[email protected]>: Stefan stepped up to be the Win32
   maintainer for JXTA-C. With his great contribution, the build
   environment is up-to-date with Visual Studio .NET, and a installer
   based on WiX is available.


New Features & Significant Changes
====================================================================
- SQL-based CM
- XPath query
- Updated build environment for Win32
- Installer for Win32
- Rendezvous capability

SQL-based CM
--------------------------------------------------------------------
The new CM is based on SQLite 3 apr_dbd driver. It is possible for you
to use a different database such as PostgreSQL or MySQL simply change the
driver. Also a SQL based CM enable wildcard search, which is missing in
previous version of JXTA-C.

XPath Query
--------------------------------------------------------------------
With XPath query, you can make discovery on an advertisement more
precisely. Note you will need a patched version of libxml2 to enable
wildcard search. You can find the patch in the lib folder.
http://jxta-c.jxta.org/source/browse/jxta-c/lib/libxml2/

Update build environment for Win32
--------------------------------------------------------------------
Stefan has made sure project files for Win32 with Visual Studio .NET is
up-to-date. He further contribute a WiX based installer, so now you
can build and distribute JXTA as static lib or DLL on Win32 in a .msi
installer package.

Rendezvous capability
--------------------------------------------------------------------
Mike has brought the Rendezvous capability into JXTA-C. With that, we
will soon be able to allow deployiment of a JXTA network with pure JXTA-C
stack. Although we still have some work to do, it is a good time for
you to look into the rendezvous implementation and to explore the
power of XPath based search in JXTA network.


Downloading and Installing
====================================================================
You can download the dist tarball from
http://download.jxta.org/build/release/c/2.2/
or alternatively directly access CVS with the tag "JXTA_C_2_2_00".

The instruction on how to build JXTA-C can be found at:

We are looking for people to maintain binary build for their favorite
OS, please let us know if you want to contribute.

Known incompatibilities between JXTA-C 2.2 and prior JXTA-C 2.x releases
====================================================================
- You need to remove your CM folder since the new CM is using SQLite.
- PlatformConfig is having a new format for rendezvous configuration.
   However, the old PlatformConfig is still usable.
- The extenal library dependencies increase as the new features are
   added. Now JXTA-C depends on libapr-1.2.1, libapr-util-1.2.1,
   libxml2-2.6.19(patch required for wildcard search), sqlite3, zlib
   and openssl.
