Java EE 8 Roadmap and Update from JavaOne 2016

Anil Gaul’s keynote showed a JEE8 plan with new scope and release targets.
Oracle says JEE must adjust to trends like cloud and microservices.

The ambitious roadmap aims for JEE8 release in 2017 and JEE9 in 2018:
jee-roadmap

The scope changes include two new JSRs: “Configuration” and “Health Check”:
jee8-revised

Surprisingly, Oracle wants to remove MVC and JMS 2.1 from JEE8 scope.
Allegedly they are “no longer very relevant in the cloud”.
Unfortunately, the roadmap also no longer mentions JCache.

The proposed JEE8 architecture stack is very focused on Java for light-weight web services:
jee8-architecture

More details are in the “Java EE 8 Update” by Linda DeMichiel:

Install portable JDK on Windows without admin rights

I found the basic idea here, the exact steps are:

iron-java-mug_120x120

  1. Install Portable 7zip
  2. Download Oracle JDK installer for Windows (*.exe)
  3. Run 7-ZipPortable.exe from your Portable 7zip
  4. In 7zip find and right-click the jdk installer exe file
  5. From the context menu use 7-Zip – Open Archive and then Extract
  6. Now extract the resulting “tools.zip” to a folder that is writable for you
  7. Open a cmd.exe, cd into the folder and execute this:
for /R %f in (.\*.pack) do @"%cd%\bin\unpack200" -r -v -l "" "%f" "%~pf%~nf.jar"

Kudos to Nick Russler for figuring out this tricky unpack200 command line!
