Java Portable (JDK and JRE)

Install a portable version of the JDK (and bundled JRE) and run it everywhere without admin rights on Windows.

The scripts don't touch your project files in any way or form.

You can:

  • Install the JDK (+ JRE) on a removable device (like USB key).
  • Run and compile application on every computer which can run Java.

Works without internet (only setup need an internet connection).

Prerequisite

  • Windows 7 and higher.
  • Powershell 2.0 or highter (see get powershell) (installed by default on Windows).

Installation

Before run, make sure that you have an active internet connection.

Run Setup.ps1 with powershell to download, create and setup the jdk files.

Run everywhere

Once you have done the installation,
Run start.bat on the computer you want to use the JRE/JDK. It will set environment variables for applications which needs Java.

That's It

Type java -version and javac -version into CMD to see if all works fine !

Shortcomings

In an environment with a Restricted PowerShell execution policy, you have to start scripts in the following way

PowerShell.exe -ExecutionPolicy Bypass -File <a script file name to start>
