10. Brief History
• Under Oracle, Java EE wasn’t flexible, barely adopting agile processes
and more open.
• 12 September 2017: Oracle announced that it’ll submit the Java EE
project to Eclipse Foundation.
• Eclipse foundation announced the new top-level project as Eclise Enterprise
for Java (EE4J)
• 26 February 2018, Java EE was rebranded to Jakarta EE
• Oracle owns and trademark the Java name.
• 10 September 2019, Jakarta EE 8 is officially released.

11. Jakarta EE 8
• Released, 10 September 2019 (https://jakarta.ee/release/)
• Full compatibility with Java EE 8 specification
• No API or namespace changes
• Compatible Products include:
• Eclipse Glassfish, version 5.1.0 and higher
• IBM Open Liberty, version 19.0.0.6 and higher
• Payara Server, version 5.193.1 and higher (Full Profile)
• Redhat Wildfly, version 18.0.0.Final and higher
• More info: https://jakarta.ee/compatibility/

12. Jakarta EE 9
• 16 January 2019, Jakarta EE Working Group approved Jakarta EE 9 Release
Plan (https://eclipse-ee4j.github.io/jakartaee-
platform/jakartaee9/JakartaEE9ReleasePlan)
• Big changes:
• javax.* namespace to be moved to jakarta.* namespace.
• Removing unwanted or deprecated specifications
• Jakarta EE 9 won’t impose backward compatibility.
• Individual Specification Version. Jakarta EE 9 will release MAJOR version of the
specification document. Thus, JPA 2.x -> JPA 3.0
• JSF 3.0 won’t be backward compatible with JSF 1.x (see first 2 sub-bullets above)
• Java SE 8 compatible. Jakarta EE 9 Web and Full Profile MUST be Java SE 11
compatible
• Possible addition of NoSQL specification: Eclipse jNoSQL

13. Coding using Jakarta EE 8

<dependency>
<groupId>jakarta.platform</groupId>
<artifactId>jakarta.jakartaee-api</artifactId>
<version>8.0.0</version>
<scope>provided</scope>
</dependency>
