Jakarta EE 8 is …
• First specification by Jakarta EE
• Minimum differences with Java EE 8
• Eclipse GlassFish 5.2
(as compatible implementation)
@knhasunuma #payara

Jakarta EE 9 is …
• Next Jakarta EE version
• Several Improvements (Plan):
• JSF 3.0, Security 1.1, JASPIC 1.2,
JACC 1.7, JAX-RS 2.2, Concurrency 1.1,
Interceptors 1.3, EL 3.1, etc.
• Those would be renamed (w/namespaces)
@knhasunuma #payara

Because show no code
• Jakarta EE 8 APIs will be almost same
as Java EE 8
• In Jakarta EE 9, old APIs could be
still used as ‘javax’ package
• No or few code should be rewritten
@knhasunuma #payara

What we should do
• Keep mind differences between Java
EE and Jakarta EE
• Understand growing Jakarta EE
become rapidly rather than Java EE
• Get involved with Jakarta EE for better
future
