# Is Glassfish v3 Ready For Production?

Glassfish v3 is not released yet. The daily builds, however, are surprisingly stable and worth evaluation. Glassfish v3 is the reference (open source) implementation of Java EE 6 but comes also with some "interesting" extensions like OSGI support. I tested the following areas so far:JSF 2.0 (navigation, data binding)EJB 3.1 -  (Stateless, Singleton and Stateful Beans) and WAR deploymentEJB 3.1 embeddable containerJPA 2.0Bean Validation (JSR-303)JMSREST (JSR-311)WebServices (JSR-181)Incremental deployment and EAR / WAR deploymentMigration of Glassfish v2 into v3JSF 2.0 -> EJB 3.1 -> JPA 2.0 -> JSR-303 combinationVarious administration console tasksMost of the http://kenai.com/projects/javaee-patterns/ projects were tested / developed with Glassfish v3Although I filed some bugs / enhancements - none of them were a real show stopper so far. Glassfish v3 is worth consideration for real world projects, but it is still fairly new technology. If you like innovation - go for it. If you don't need the Java EE 6 features, Glassfish v2 is still a good choice.
