With the greatest pleasure I can report that WebLogic 12.2.1 has recently been fully Java EE 7 certified! This represents full commitment from Java steward Oracle to commercial support for Java EE 7. WebLogic joins the ranks of GlassFish 4, WildFly 8, WebSphere Liberty Profile 8.5, Hitachi Cosminexus and TmaxSoft JEUS. With the very broad customer base that both Oracle and WebLogic have globally this is very welcome news for Java EE 7 indeed. All of the Java EE certified offerings are always listed on the official Java EE compatibility page.
As many of you are aware, Java EE 7 is one of the most extensive set of changes to the platform in it's history. Similarly WebLogic 12.2.1 is one of the most significant releases of WebLogic in many years, even not counting full Java EE 7 support. In addition to Java EE 7 support WebLogic 12.2.1 brings two significant sets of changes.
The first is what is referred to as multitenancy. WebLogic multitenancy brings greater isolation similar to what one can accomplish through Linux containers like Docker or traditional virtualization - only applied natively at the WebLogic runtime level. What this means is that multiple applications can run completely isolated from each other on the same WebLogic runtime as though they were running on different domains. The multitenancy concept is intended to be implemented seamlessly across Oracle products in the data center including the Oracle JDK, Coherence, Traffic Director and the Oracle Database. This is a concept currently unique to the Oracle stack.
WebLogic 12.2.1 also builds on the traditional strengths of the product with regards to high availability. A number of features have been added to improve 100% up time capabilities through live patching, live upgrades, clustering, load-balancing, fail-over and replication, especially in large, multi data center, disaster recovery capable deployments.
The following are the most important links you should explore:
It is worth reminding that prior to 12.2.1, the WebLogic 12.1.3 release supported the Java EE 7 APIs that many customers indicated they thought were most important - WebSocket, JSON-P, JAX-RS 2 and JPA 2.1. Also note that like 12.1.3, WebLogic 12.2.1 is certified for Java SE 8. Though it is not there yet, WebLogic 12.2.1 will soon also be available on the Oracle Cloud - representing full Java EE 7 commercial support on the cloud from Oracle.
So the question now is who will be next to cross the Java EE 7 compatibility finish line. JBoss EAP 7 recently released an alpha with Java EE 7 support - this is in addition to Red Hat's long standing Java EE 7 compatibility through WildFly. Similarly WebSphere Classic released a beta showing Java EE 7 support in addition to the existing IBM full commercial Java EE 7 support through WebSphere Liberty. It is clear there will be at least two more significant Java EE 7 commercial platforms in the next few months. The Apache TomEE team is also working on bringing forward Java EE 7 features.
For some perspective, few other open standards such as SQL have as many available implementations as Java EE 7 already has.
