Subject [PROPOSAL] CeltiXfire Project
Date Tue, 20 Jun 2006 17:52:02 GMT

Below is a project proposal for incubation consideration. 
The project welcomes your feedback as well as interest in involvement. 
This proposal is also located online at

== CeltiXfire Proposal ==

Project CeltiXfire is a SOA infrastructure framework focused on implementation of JCP and
web service standards while also providing extensibility for legacy integration. It is a merge
of two matured open source projects and communities, ObjectWeb Celtix (
and Codehaus Xfire ( It will implement the JAX-WS, JAX-WSA, and
JSR-181 standards. Core to this is support for web service standards like SOAP 1.1, SOAP 1.2,
WS-I BasicProfile, WS-Security, WS-Addressing, WS-RM, and WS-Policy. This project will support
several programming models like JAX-WS, JBI (ServiceMix), SCA (Tuscany), and CORBA services
(Yoko).  We will leverage open source components wherever possible, for example we intend
to use WSS4J for ws-security from the Apache Web Services project. One goal of this project
is to provide public APIs that match the JSR standards. Furthermore, the scope of this project
is to provide SOA infrastructure for both modern web services and for legacy systems. The
seed code has been designed to provide a pluggable architecture to support both XML and non-XML
type bindings in combination with any type of transport. For example, Celtix is in the process
of being extended to provide a CORBA binding as part of the Apache Yoko project (in incubation).
Additional examples of non-XML bindings that could be supported in the future include fixed
length record bindings, which are critical to integrating mainframe systems into a SOA. The
current infrastructure code is designed for flexible deployment in a variety of containers
including JBI, J2EE, SCA and servlet containers.
== Rationale ==
The project is interested in moving to Apache for the following reasons: To provide Apache-licensed
implementations of the relevant web service JSR standards: JAX-WS, JAX-WSA, JSR-181, and JSR-265
standards and to test those implementations with the applicable JSR TCKs, to become better
integrated with the Geronimo, Harmony, ServiceMix, Tuscany, Yoko and Apache Web Services communities,
and to build a strong vendor-neutral community that will outlast any one person's or company's
== Meritocracy ==
The Codehaus Xfire and ObjectWeb Celtix projects have fostered a development community based
around meritocracy. Many of the committers already work on other Apache projects and understand
the Apache way. The individuals understand that they are responsible for the code, and that
the community around the project will define the direction.

== Community ==
The CeltiXfire Community will bring together two already successful communities - Xfire and
Celtix. Both projects have active users and contributors on the mailing lists.

== Core Developers ==
The CeltiXfire project's initial committers include a diverse set of individuals. Some of
the individuals are employed by Envoi Solutions, IONA, BEA, LogicBlaze and Red Hat, and some
are not funded by any particular employer.

== Alignment ==
CeltiXfire currently uses and integrates with many Apache projects but does not have hard
dependencies on these (in alphabetical order): 
 * ActiveMQ is used as the default JMS implementation. 
 * Continuum: Apache Continuum currently uses XFire for its SOAP integration. 
 * Harmony: Harmony is implementing Java 5.0 and requires support for many of the JSR that
CeltiXfire will provide. 
 * Jakarta Commons HttpClient can be used for the HTTP client transport. 
 * Geronimo: Celtix already provides Geronimo integration. CeltiXfire will continue this effort
and will be made available so that Geronimo could use CeltiXfire as its JAX-WS implementation
for JEE. 
 * ServiceMix: Codehaus XFire is currently used within ServiceMix to provide web service integration.
Celtix provides its own JBI integration for ServiceMix as well, although JBI is an option
and not a requirement for Celtix implementation. 
 * Maven 2: Celtix and Xfire already provide Maven 2 plug-ins for invoking the Celtix and
Xfire tooling. 
 * Tuscany: Celtix is already integrated with Tuscany. 
 * WSS4J: CeltiXfire uses Apache WSS4J for WS-Security support. 
 * XMLBeans is currently used as one of the data-binding options for CeltiXfire. 
 * XmlSchema: CeltiXfire uses XmlSchema for many schema related functions internally. 
 * Yoko: Celtix is already integrated with Yoko to provide support for exposing CORBA services
as web services.
We are currently evaluating the use of other Apache projects as well like Woden, Neethi and

== Avoiding the Warning Signs ==

=== Orphaned products ===
CeltiXfire is a merging of two successful open source projects, ObjectWeb Celtix and Codehaus
Xfire. Both have active communities and developers. CeltiXfire provides support for some important
specifications to Java community, we expect that this project will continue to grow and develop
within its own community, and be embraced by many other open source projects as well. 

=== Inexperience with open source ===
The authors of the existing code have extensive experience with open source already.  The
initial list of committers includes 9 Apache Committers.  They are involved in: 
 * Apache Continuum 
 * Apache Geronimo 
 * Apache ServiceMix 
 * Apache Tuscany 
 * Apache Yoko 

=== Homogeneous developers ===
The project's initial committers include individuals that are employed by a diverse set of
companies, including Envoi Solutions, IONA, LogicBlaze, BEA and Red Hat.  About 2/3 of the
initial committers are employed by IONA.  Additionally the project has several committers
whose work is not funded by any particular employer.  

=== Reliance on Salaried Developers ===
Many of the developers are salaried, but they are spread out over several organizations. Several
other developers are contributing to this project without any connection to an employer. 

=== No ties to other Apache products ===
Both ObjectWeb Celtix and Codehaus Xfire currently use many Apache projects. These have been
outlined in the "alignment" section.
=== A fascination with the Apache brand ===
While we expect the Apache brand may help attract more contributors, our interests in starting
this project is based on the factors mentioned in the Rationale section.  However, we will
be sensitive to inadvertent abuse of the Apache brand and will work with the Incubator PMC
and the PRC to ensure the brand policies are respected.  

=== Scope of Subprojects ===
No subprojects proposed.

== Initial Source ==
The Celtix codebase is owned by IONA. It is currently available under both EPL and LGPL licenses
( The applicable code will be relicensed under the Apache License
2.0. The Codehaus Xfire codebase is owned by Envoi Solutions LLC and is available under an
MIT license ( The applicable code will be relicensed under the
Apache Software License 2.0. The dependencies all have Apache compatible licenses. These include
BSD, CDDL, CPL, MPL and MIT licensed dependencies.
