Since delivering Java EE 7 Full Platform compliance back in June, we’ve been finishing off some of the other WebSphere Liberty features that we’ve beta’d over the past few months.

New features in Liberty

Find out more about all the new features in the Liberty Repository.

  • REST API Discovery
    • You can now discover REST APIs available on a Liberty server with a new Swagger-based discovery model! Simply add the apiDiscovery-1.0 feature to your Liberty instances, add a swagger.json file to your web module’s META-INF folder. Alternatively, configure a different URL (see the documentation) and you’ll be able to fetch an aggregated swagger.json via the URL https://host:https_port/ibm/api/docs if you want to work with the raw JSON data, or you can visualize the attractive UI at https://host:https_port/ibm/api/explorer, which lets you navigate and invoke your REST APIs from the browser. Try it out!
    • There’s a wizard to create the swagger.json file to define the REST API document. You have two options:
      • Create a template swagger.json file, which will create a META-INF/swagger.json file consisting of just the top level required Swagger elements.
      • Create a sample swagger.json file, which will create a META-INF/swagger.json consisting of a number of generated configurations.

  • Federated User Registry
    • Support for federating multiple user registries.
  • OSGi Http Whiteboard
    • Deploy modular Web applications written using Servlet technologies and the OSGi HTTP Whiteboard specification.
  • Media Server Control
    • Access media servers using the JSR309 API.
    • For applications to use this API, a driver implementation of JSR309 must be installed.
  • System for Cross-domain Identity Management
    • Invoke the User Management API using SCIM REST Services.
  • Kerberos Constrained Delegation for SPNEGO
    • Support for Kerberos constrained delegation for SPNEGO.
  • WSSecurity SAML
    • Support for the SAML Assertion in the Web Service Security version 1.1 function.

Also new in this release

  • Migration Toolkit
    • The migration toolkit has been updated to provide more assistance for migrating to Liberty.
    • Both the Eclipse source scanning and binary scanning tools are updated with new and updated rules for Java EE 6 to Java EE 7 migration, as well as WebSphere classic to Liberty migration.
    • The binary scanning tool can now generate reports in multiple languages.
  • Find and install features from within the Server Configuration Editor
    • Can’t find the features you’re looking for? Install them right from the Add Features dialog! Convenient right?

  • Install content from local repositories
    • Don’t have access to the online Liberty Repository? Use a local repository instead. Local repositories are folders or zip files containing installable Liberty features and/or addons. Configure WebSphere Developer Tools to access your local repositories and install away.
