What’s in the WebSphere Liberty beta for April?

Validator feature

The validator-1.0 feature allows you to test your data source configuration without having any applications installed or updated to use the data source. You can provide resource reference information for the test operation which allows the data source to be tested in the same way that your application uses it, allowing you to debug database configuration related issues without involving your application.

Logstash Collector and Bluemix Log Collector updates

The maximum length of the message field in liberty_message, liberty_trace and the stackTrace field of liberty_ffdc was previously fixed to 2048 characters. Some messages may have included a long Java stack trace and would have been truncated after 2048 characters.

You can now customize the maximum length by setting the new attribute maxFieldLength in the logstashCollector and bluemixLogCollector element. The default value is 2048. Specify “-1” if you do not want to limit the length of the message and stackTrace field.

Enhancements to the Java Batch Tool in the Admin Center

  • You can now purge a job instance. This will remove all database entries and job logs associated with the job instance. An option to purge only the job store will be made available.

  • Additional search criteria will be made available for narrowing the list of job instances displayed on the Java Batch Tool dashboard. These include search by Last Update range, Submitter, Application Name, and Job Name.

WebSphere Developer Tools updates

Projects with a location outside your Eclipse workspace can now be deployed to a Liberty Docker server when running applications directly from the workspace.

This means that you can use the running applications directly from the workspace mode with a Liberty Docker server even when your projects are imported from a local git repository. If you deploy one of these projects to the server it will automatically create a new container with the volumes needed to access that project and other projects in the same directory locally.

What’s already in there?

The March 2017 beta included the MicroProfile Config feature and the MicroProfile Fault Tolerance feature.

Take a look at the previous beta announcements for a full list of stuff added since the 16.0.0.2 release in June 2016:
