Installing Java

   

What is the offline method for downloading and installing Java for a Windows computer ?


This article applies to:
  • Platform(s):
    Windows 98, Windows ME, Windows 2000 (SP4+), Windows XP (SP1 SP2), Windows 2003
  • JRE version(s):
    1.4.2_xx


 The procedure to install the JRE broadly consists of:
  1. Download and Install
  2. Enable and Configure
  3. Test Installation

This process requires you to download an executable file (e.g., j2re-1_4_2_xx-windows-i586-p.exe, appx. 15 Mb size) that includes all the files needed for the complete installation. You do not need to remain connected to the Internet during the installation. The file can also be copied to a computer that is not connected to the Internet.

    After reading the agreement, click the Yes button to accept its terms and continue with the installation.

    The installer then displays a Setup Type screen that allows you to choose either a typical or custom setup. We recommend that you choose the Typical option (the default selection) unless you are an advanced user who wants more precise control over the components that will be installed.

    Now that you have given the installer all of the information it needs to proceed, progress boxes track the installation process.
