Eclipse Metro
Metro is a high-performance, extensible, easy-to-use web service stack. Although historically an open-source part of the GlassFish application server, it can also be used in a stand-alone configuration. Components of Metro include: JAXB RI, JAX-WS RI, SAAJ RI, StAX and WSIT. Originally available under the CDDL and GPLv2 with classpath exception, it is now available under
History
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".
Features
Metro compares well with other web service frameworks in terms of functionality. Codehaus started a comparison which compared Apache Axis 1.x, Axis 2.x, Celtix, Glue, JBossWS, Xfire 1.2 and JAX-WS RI + WSIT. This was later updated by the ASF to replace Celtix with CXF and to include OracleAS 10g.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.Its features include:
- Basic Profile 1.1 Compliant
