About this community

This is a user group for Jakarta EE and MicroProfile in Japan.

Enterprise Java technology, which began with Java EE (J2EE), has now been renamed Jakarta EE and MicroProfile. It continues to evolve under the Eclipse Foundation as a vendor-neutral, community-driven initiative.
In addition to the reliability and compatibility traditionally required for enterprise systems, innovative technologies for cloud-native systems are also being addressed.

If you are interested in Jakarta EE or MicroProfile, the standard specifications for server-side Java, we encourage you to join us.
