What’s already in there?

  • Optimized Adapters (WOLA): Close integration of classic applications on z/OS with those running in the Liberty profile for z/OS. Set of APIs for bi-directional calls between applications on Liberty profile and in CICS, z/OS Batch, and z/OS UNIX System Services (USS).
  • OpenID: Allows for Liberty profile security integration with an OpenID Security Provider such as Google, Yahoo, and others. Based on the OpenID 2.0 open standard.

  • WebSockets: Partial support for the Java API for WebSockets. Includes connection initiation, message reading and writing, ping, pong, most annotations, and message decoding and encoding.
  • Java 8 toleration: Allows the Liberty profile to run with fewer errors on a Java 8 virtual machine. Applications still need to be compiled with Java 7.
  • Connector Architecture: Standard architecture for integrating Liberty profile and Enterprise Information Systems (EIS). Based on Java EE Connector Architecture V1.6 technology.
  • EJB Lite version 3.2: Initial support for the ‘lite’ subset of the Enterprise Java Beans version 3.2 spec. Includes support for non-persistent EJB timers and asynchronous EJB methods.
  • Java EE Concurrency Utilities 1.0: Ability to configure and use server-managed executors, scheduled executors, thread factories, and the thread context service. Thread context capture and propagation includes the classloader context, the Java EE metadata context, and the security context.

      There is a production version of the WebSphere Liberty Profile available in our WebSphere 8.5.x product stream, the most recent level of that stream is

      The content in this beta is the technologies the WebSphere development team is working on and we are looking for feedback from our users. We don’t have a specific timeline as to when all of these feature will be released, we are using an agile development and continuous delivery model to release our highest priority features to our clients as quickly as possible.

      However, since you specifically asked about JCA, you can see from our latest announcement last week that we will be releasing the JCA support (along with several other features from the beta) as a new feature in our Liberty repository
      on June 13, 2014. These features will be optionally installable on top of an product level.
