CDI support in GlassFish 3.1

GlassFish 3.1


A new release of GlassFish, GlassFish 3.1, is here, and there is enhanced support for the dependency injection and contextual lifecycle management capabilities offered by the Contexts and Dependency Injection specification in it.

As you would know, GlassFish integrates the reference implementation of the CDI specification, Weld, to support CDI. GlassFish 3.1 integrates the latest release of Weld, Weld 1.1.0. Weld 1.1.0 was released a month ago and its main focus was on making "significant improvements in memory usage, boot-time and runtime performance" compared to the earlier release. More details on the release may be found here.

One of the major themes in the GlassFish 3.1 release is improved support for clustering and high-availability. With GlassFish 3.1's support for persisting session state (HTTP) using in-memory session replication, it is now possible to have an application's ConversationScoped and SessionScoped Beans highly-available, thereby minimizing disruption for users of the application when a server instance fails.

In addition to this integration, we have worked on better tooling support and streamlining the integration process. So, please try the new release and share your feedback with us.
