Metro is a high-performance, extensible, easy-to-use web servicestack. Although historically an open-source part of the GlassFishapplication server, 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. Originally available under the CDDL and GPLv2 with classpath exception,[2] it is now available under Eclipse Distribution License [Wikidata]
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 was decided to bundle these two components as a single component named Metro.[3]
Features
Metro compares well with other web service frameworks in terms of functionality. Codehaus started a comparison[4] which compared 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 that time). This was later updated by the ASF to replace Celtix with CXF and to include OracleAS 10g.[5]
Metro includes JAXB RI, JAX-WS RI, SAAJ RI, SJSXP, and WSIT, along with libraries that those components depend on, such as xmlstreambuffer, mimepull, etc.[6]
Metro augments the JAX-WS environment with advanced features such as trusted, end-to-end security; optimized transport (MTOM, Fast Infoset), reliable messaging, and transactional behavior for SOAP web services.
Market share
Metro is bundled with Java SE 6 in order to allow consumers of Java SE 6 to consume Web Services.[7]
Metro is bundled with numerous application servers such as:[8]
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.
