This blog is created to show how to convert the JDK exe file into portable package.

JDK8 Portable

Follow the below stepts.

For JDK 8u102 things have changed, this worked for me:

1) Download windows JDK exe

2) Open with 7-Zip

3) Dump contents into a directory %JDK-EXE% cmd: cd %JDK-EXE%.rsrc\1033\JAVA_CAB10 cmd: extrac32 111

4) Now have a in directory, open it in 7-Zip

5) Extract contents into a new directory %JDK-VERSION% cmd: cd %JDK-VERSION% cmd: for /r %x in (*.pack) do .\bin\unpack200 -r “%x” “%~dx%~px%~nx.jar”

6) is in a linux download: jdk-VERSION-linux-x64.tar.

7) Put a copy into %JDK-VERSION%

Now you are ready to go. You might want to setup JAVA_HOME and PATH to point to your %JDK-VERSION% dir and its BIN subdir.

JDK7 Portable

Follow the below stepts

1) Create destination folder where you can place the jdk (e.g. C:\jdk8)

2) Download jdk exe from Oracle (e.g. jdk-8u72-windows-x64.exe)

3) Unzip the found inside it into the destination folder

4) In cmd.exe, run: cd C:\jdk8 for /r %x in (*.pack) do .\bin\unpack200 -r “%x” “%~dx%~px%~nx.jar”

This solution works for JDK 8 too, without Admin rights.
