Introduction

This post explains how to create JDK folder from the installation exe in Windows. This will be help full for people who don’t have admin privilege to install JDK.

PS. I have tested this with JDK 1.7.0 Update 51 in windows 7.

Steps

  1. Download JDK from Oracle
  2. Download and Install 7-zip from here
  3. Open installition exe using 7-Zip
  4. Extract the tools.zip
  5. Extract the content of tools.zip to a folder (e.g. c:\jdk).
  6. Open the extracted folder in cmd prompt.
  7. Execute for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" command
  8. Set JAVA_HOME to the jdk (e.g c:\jdk) folder.
  9. Add %JAVA_HOME%/bin to the PATH env variable.

Testing

Run the following command to check the installation, it will print the version of JDK.

c:> javac -version
javac 1.7.0_51
