  • Introduction to New AutoScale Feature Available in Payara Server

    When AutoScale is fully developed, not only will it allow you to change the number of instances in the Deployment Group by implementing additional asadmin commands, but it will also signal the routing systems of the changed configuration and automatically trigger a change in size based on rules around resource usage.

    In this first step of the AutoScale development, we have introduced the concept of the Scaling Group into Payara Server Community Edition 5.2021.4 which can alter the number of instances in a Deployment group and implement it for SSH nodes.

    The AutoScale feature is in continuous development, with improvements and additional functionality (including addressing the routing issue) planned in our future releases.

  • How to Use Eclipse Transformer to Convert a 3rd Party Library to the New Jakarta Namespace

    The release of Jakarta EE 9 breaks a tradition of Java Enterprise. A legal requirement of the Java EE code donation from Oracle to the Eclipse Foundation is the change of the namespace of javax to jakarta.

    But the change of the package and XML namespace in Jakarta EE 9 is only the beginning. The change of the namespace allows for new development and functionality, but all frameworks and libraries using one of the Java Enterprise specifications also need to be adjusted to the new version.
