Jakarta Data provides an API to allow easy data access technologies. Thus, a Java developer can split the persistence and the model with several features such as a Repository interface with the method by query, where the framework will implement it.
The Eclipse Digital Cockpit provides an Edge Runtime focused on industrial automation. It stands somewhere between a simple Edge Runtime, an "Android for the machine" and a lightweight "Application Server" where services and Apps can be deployed to.
Besides the Edge Runtime there are multiple backends like an App Store (under development) or a Telemetry Backend which takes telemetry values that Apps or Services from the Cockpit send out.
Eclipse JustJ provides fully-functional Java runtimes that can be redistributed by Eclipse Projects. The form in which these are made available is intended to make these easily consumable. As such, the Java runtimes will be available via p2 repositories as well as via direct packaged downloads. The links for these will evolve over time. The sources of these Java runtimes are any and all versions approved by the Eclipse Foundation for such purposes. Currently that is limited to the latest release available via https://jdk.java.net.
The Eclipse Phizog project goal is to provide the reference implementation based on the Object Management Oriented Data Distribution Service (OMG DDS) for the FACE-TSS.
