GlassFish Metro

Metro is an opensource web service stack that is a part of the GlassFish project, though it can also be used in a stand-alone configuration.[1] Components of metro include JAXB RI, JAX-WS RI, SAAJ RI, StAX (SJSXP implementation) and WSIT. It is available under the CDDL and GPLv2 (with classpath exception.)[2]

History[edit]

Originally, the Glassfish project developed two semi-independent projects :

  • JAX-WS RI, the Reference implementation of the JAX-WS specification
  • WSIT, a Java implementation of some of the WS-* and an enhanced support for interoperability with the .NET Framework. It is based on JAX-WS RI as "Web Service layer".

In June 2007, it has been decided to bundle these two components as a single component named Metro[1].

Market share[edit]

Metro is bundled with Java SE 6 in order to allow consumers of Java SE 6 to consume Web Services [2]

Metro is bundled with numerous Application Servers [3] such as :

The JAXB reference implementation developed for Metro is used in virtually every Java Web Services framework (Apache Axis2, Codehaus XFire, Apache CXF) and Application Servers.

Features[edit]

Metro compares well with other web service frameworks in terms of functionality. A comparison is provided by Codehaus at [4], which compares Apache Axis 1.x, Axis 2.x, Celtix, Glue, JBossWS, Xfire 1.2 and JAX-WS RI + WSIT (the bundle was not yet named Metro at this time).
