"We've got some process automation cleanup to do but that aside JXTA 2.3 is 'out the door.' The announcement is not yet available in the archives and as such I'll inline the doc here ... pretty impressive."



"Community Members,

We are pleased to announce the availability of JXTA J2SE 2.3 "Jambalaya". A lot of progress has been made in this release and there is a lot to be excited about! The JXTA Jambalaya release provides significant functional enhancements of the JXTA J2SE platform, some important performance and scalability improvements, along with a number of important bug fixes. Please see for more information about what's new.

This release is designed to be API and protocol backwards compatible with other JXTA J2SE 2.x releases. This release is recommended for all JXTA users, developers and deployers.

The JXTA J2SE Release Team

...New Features & Significant Changes

====================================================================

* Refactored Endpoint Service for Performance and Scalability
* Enhanced PSE Membership Service
* Enhanced Configuration -- NAT detection
* Refactored Rendezvous Service for Performance and Scalability
* Shell Cleanup

Enhancements to the Endpoint Service

------------------------------------

The old endpoint service implementation tried to provide the illusion that infinitely large messages could be sent in parallel between arbitrary peers. Other services were also forced to write special purpose code such as messenger caches to overcome these limitations.

The new design renounces the illusion of infinite datagrams in favour of clarity of purpose in the code, true scalability and generally better performance. New API functionality is available for application developers to write more scalable services and applications.

Enhanced PSE Membership Service

-------------------------------

The PSE Membership now uses regular Java KeyStores for storing all certificates and keys, it has a new listener API for monitoring credential expiry and authentications, and it now has full support for certificate chains. The login UI has changed slightly to allow for the entry of separate keystore and key passphrases.

Enhanced Configuration -- NAT detection

---------------------------------------

The ext:config (net.jxta.ext.config) library now includes functionality for live probing of NAT configuration. It does this by contacting a server which attempts to perform a reverse connection. This probing enables better automatic configuration of peers.

Performance and Scalability

---------------------------

The Rendezvous Service received a major refactoring to improve code clarity, reliability and scalability. The new Rendezvous Service takes advantage of the new Endpoint Service in order to make more efficient use of resources. It also sends fewer messages between peers to maintain the peerview and process propagations.

Shell Cleanup

-------------

The Shell and a large number of the commands have received cleanup. It's now a lot more clear and simpler to write your own shell commands or figure out how to use JXTA by examining how the Shell commands work. The Shell also now includes a status line which helps determine the real-time state of the network.

Downloading and Installing

====================================================================

Prebuilt JXTA J2SE 2.3 builds can be installed from :

* JXTA 2.3 download

You can also build from cvs :

cvs -d:pserver:guest@cvs.jxta.org:/cvs co -r JXTA_2_3_00 \
platform shell security cms myjxta2

Each module has an Apache Ant build.xml file located in the 'binding/java/' directory. You can build each module with the following commands:

% cd security/binding/java
% ant dist

These commands should be repeated for each module. Some of the modules depend upon other modules being built first. Build the modules in the following order: security, platform, shell, cms, myjxta2.

The following wiki page provides simple instructions for building JXTA using Ant:

Known Incompatibilities between JXTA 2.3 and prior JXTA 2.x releases

====================================================================

A number of deprecated APIs have been removed in this release. See the "Impacts to Developers" section below for details.

Impacts to Current Users : LOW

====================================================================

JXTA J2SE 2.3 should a drop in replacement for any application currently using JXTA J2SE 2.2.1 or 2.2

Impacts to Developers : MEDIUM

====================================================================

The following deprecated APIs were removed in JXTA 2.3

* net.jxta.util.config package
* EndpointFilterListener
* EndpointMessenger
* net.jxta.JxtaUtilities
* Endpoint.newMessage
* Endpoint.newEndpointAddress
* PipeService.createMessage

Pay careful attention to the deprecation messages generated when compiling your application. JXTA J2SE 2.3 introduces several new deprecations. The next planned release (Yaprakh) will remove some interfaces which have been deprecated since JXTA J2SE 2.1 :

* JxtaTimer
* RdvMonitor
* RdvManager
* SimpleRdvManager
* net.jxta.util.*Utilities
* SimpleRdvMonitor

Avoid ever importing any symbols from the net.jxta.impl.* packages. The classes and methods in these packages may (and will) change from release to release, sometimes drastically and *no* effort will be made to retain compatibility of programs which depend upon "impl" packages. YOU HAVE BEEN WARNED!

If there is no alternative available to importing from "impl", please file an issue against the platform so that an alternate mechanism can be developed.

With the next release (Yaprakh) the Membership service will no longer automatically present the login dialog at startup. Application will be required to perform authentication based upon their own needs. See: http://wiki.java.net/bin/view/Jxta/NoAutoLogin and http://wiki.java.net/bin/view/Jxta/PasswordTopic for more info.

Impacts to Deployers / Rendezvous Managers : LOW

====================================================================

This release includes significantly improved performance and stability for the rendezvous and relay peers. Rendezvous operators should plan on upgrading to JXTA J2SE 2.3 as soon as possible. JXTA J2SE 2.3 should be a drop in replacement for JXTA J2SE 2.2 releases.

Before restarting rendezvous/relays you should clear your cm directory. (It can also be argued that rdv/relays may benefit from doing this with every restart).
