Metro, the GlassFish Web Services stack (Metro) continues to gain adoption. Jitu reports its presence in the JDK used in WAS 7.0 (open beta). Previous reports include JBoss 5.0 and Oracle (nee BEA) WebLogic Server. This is not surprising: the performace of Metro is very good (see, for instance, yesterday's testimonial), its interoperability is outstanding, it's Flexible Architecture supports multiple Encodings and Transports, includes REST suport via Jersey, the licenses (GPLv2+CDDL) are very usable, it has a Growing Community and great Tool Support in NB 6.1 and is an Award-Winner.

Metro is directly available in the enterprise-ready GlassFish v2 as well as in the modular GFv3, as well as in Sun's JDK. And, if you really insist, we even show you how to Install it on Tomcat :-)

Developer.com awards a Product of the Year and this year several of our family, friends and relatives are winners: Metro, NetBeans, JSR 223, JavaSE 6 and PostgreSQL. Full details in the Developer.COM article: [1], [2].

I was "on vacation" last week, so the news are a bit late, but the news on July 1st confirmed the rumor: Oracle WebLogic Server is Oracle's "Strategic AppServer" - see the articles at The Register and InfoWorld. This comes on top of recent surveys on Oracle/BEA usage: SOA-Talk and The Register.

A consequence of this move is that Metro is now used Oracle's main AppServer, increasing the adoption of GlassFish's WebServices stack. The same applies to JAXB RI; and, in that case, I know of no mainstream AppServer that uses a different implementation!

Thomas announced that JBossWS 2.1.0 will support Metro, the GlassFish WS Stack (Thomas' blog, Vivek's). Other uses include GF v2 (and SJS AS 9.1), TmaxSoft JEUS 6 and WebLogic Server 10. Metro is designed to be extensible and integrateable and also works on Jetty and Tomcat - I'd venture it should not be hard to use inside Geronimo, so let us know if you attempt that effort.

PS - The map shown is that of Barcelona's Metro. It does not include the future Linea 9.
