JAX-WS Project Created on

Posted by kohlert on November 3, 2005 at 9:15 AM PST

A new JAX-WS project has been created on This project is for the reference implementation of JSR 224 that Java API for XML Web Services.

Originally JAX-WS 2.0 was named JAX-RPC 2.0 and was part of the JAX-RPC project. Even after JAX-RPC 2.0 was renamed to JAX-WS 2.0 (see my blog) the two projects continued to share the JAX-RPC project. To clarify that these are in fact two seperate projects and to remove some confusion about them, we have created a JAX-WS project to focus solely on JAX-WS.

JAX-WS is the next generation standard for Java Web Services. It has significant advantages and improvements over JAX-RPC. One of the biggest wins for developers is that JAX-WS will be included in Mustang (Java SE 6). This means that writing JAX-WS clients will not add additional libraries to the client application. In addition to the features I mentioned in
JAX-WS 2.0 EA blog
a number of other features are also included in the new feature complete implemenation.
These features include:

  • MTOM
  • SOAP 1.2
  • XML centric apis Dispatch and Provider
  • Java SE based Endpoints (no need for a servlet container for lightweight endpoints)

  • All of this and JAX-WS produces significantly smaller
    applications than JAX-RPC.

    The JAX-WS project can be found at
    The mailing list will be used to discuss issues related to JAX-WS. To subscribe to the list, send a message to:<>

    JAX-WS is an open source project with the CVS repository accessible from the JAX-WS project along with the API documentation, source and nightly builds of the JAX-WS source.
