Eclipse Metro

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.{{cite web |last=Gupta |first=Arun |date=2007-06-19 |df=mdy |title=Announcing Metro - Naming the Web Services stack in GlassFish |department=Miles to go… |website=blogs.sun.com |url=http://blogs.sun.com/arungupta/entry/announcing_metro_naming_the_web |archive-url=https://web.archive.org/web/20090926144443/http://blogs.sun.com/arungupta/entry/announcing_metro_naming_the_web |archive-date=2009-09-26}}

Metro compares well with other web service frameworks in terms of functionality. Codehaus started a comparison{{cite web |title=Stack Comparison |department=XFire |website=xfire.codehaus.org |url=http://xfire.codehaus.org/Stack+Comparison |archive-url=https://web.archive.org/web/20061230114334/http://xfire.codehaus.org/Stack+Comparison |archive-date=2006-12-30}} 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.{{cite web |title=StackComparison |department=Apache Web Services Wiki |website=Apache Wiki Farm |url=https://wiki.apache.org/ws/StackComparison |archive-url=https://web.archive.org/web/20170904141955/https://wiki.apache.org/ws/StackComparison |archive-date=2017-09-04}}

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.{{Cite web|url=https://metro.java.net/discover/faq.html|title = Metro}}

Its features include:

• Basic Profile 1.1 Compliant
• Easily Create Services from POJOs
• RPC-Encoding
• Spring Support
• REST Support
• Soap 1.1/1.2
• Streaming XML (StAX based)
• WSDL 1.1 ->Code (Client)/(Server)
• Server and Client-side Asynchrony

Supported WS-* Standards

Supported Transport protocols include:

• HTTP
• JMS
• SMTP/POP3
• TCP
• In-VM

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.

Metro is bundled with Java SE 6 in order to allow consumers of Java SE 6 to consume Web Services.{{cite web |title=JAX-WS FAQ |website=jax-ws |url=https://jax-ws.dev.java.net/faq/index.html#different_versions |archive-url=https://web.archive.org/web/20070807124130/https://jax-ws.dev.java.net/faq/index.html#different_versions |archive-date=2007-08-07}}

Metro is bundled with numerous application servers such as:{{cite web |last=Gupta |first=Arun |date=2007-07-22 |df=mdy |title=Metro - Now on Tomcat 6.x also |department=GlassFish |website=blogs.sun.com |url=http://blogs.sun.com/theaquarium/entry/metro_now_on_tomcat_6 |archive-url=https://web.archive.org/web/20090615134727/http://blogs.sun.com/theaquarium/entry/metro_now_on_tomcat_6 |archive-date=2009-06-15}}

• GlassFish
• Sun Java System Application Server Platform Edition 9.x
• Oracle WebLogic Server
• JBoss (version 5.x only)
• TmaxSoft JEUS 6.x

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.
