Here’s the latest WAS Liberty beta and WebSphere Developer Tools (WDT).

Thanks to your support for our beta programme, we were able to release WAS Liberty with Java EE 7 Full Platform support on 25th June 2015!

Look out for more betas over the coming months.

What’s in the WAS Liberty beta for December 2015?

Web Services Atomic Transaction Enable this capability with <feature>wsAtomicTransaction-1.2</feature> in your server.xml . A transaction that is started on one server can be extended to include resources updated on other servers via web service calls. When the transaction is finally committed (or rolled-back) all the transactional resources on both the local and remote machines will be guaranteed to be either all committed or all rolled-back as one atomic operation. The feature supports handling of both in-bound transactions when processing web service requests from other servers (including Liberty and Classic WAS) and propagating out-bound transactions when web service calls are made. Transactions are, as would be expected, fully logged and will be correctly handled and recovered in the case of any failure at any point in the distributed environment. For more information, see the OASIS Web Services Atomic Transaction standard.

Updates to REST API discovery The apiDiscovery-1.0 feature now supports auto-generation of Swagger 2.0 documents from JAX-RS 1.1 and 2.0 annotated web apps! These JAX-RS apps can also be annotated with Swagger annotations, which will be used to provide additional content to the generated document. Just deploy your JAX-RS application onto a Liberty server running this beta driver (with apiDiscovery-1.0 configured) and you will see the REST APIs automatically show up in the /ibm/api/explorer view! Also new is a collective-wide Swagger 2.0 document of your REST APIs. Just add apiDiscovery-1.0 to your collective controller and to any collective member that wants to expose REST APIs, and when you hit /ibm/api/collective/docs in the collective controller you will see a Swagger 2.0 document that aggregates all of the REST APIs being exposed in the collective. Stay tuned for a corresponding UI view of this new endpoint.
