Applications do not only present a UI for the user or supply the data through REST endpoints, many of them also offer data as a file download. Generated documents, data exports, and so many other types of downloads are very common. Jakarta EE, supported by the Payara Platform products, have various ways of generating these.

    Introduction 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.

  • 10 Strategies for Developing Reliable Jakarta EE Applications for the Cloud 27 Nov 2020

    What happens when an application designed for a small user base needs to be scaled up and moved to the cloud? It needs to live in a distributed environment: responding to an appropriate number of concurrent user requests per second and ensuring users find the application reliable.  Though Jakarta EE and Eclipse MicroProfile can help with reliable clustering, there is no standard API in Jakarta EE that defines how clustering should work currently. This might change in the future, but in the meantime, this gap must be filled by DevOps engineers. In this blog, we will cover 10 technical strategies to deal with clustering challenges when developing Jakarta EE and MicroProfile for cloud environments.
