Installing Java

   

What is the manual method for downloading and installing Java for my Windows computer ?


This article applies to:
  • Platform(s):
    Windows 98, Windows ME, Windows 2000 (SP4+), Windows XP (SP1 SP2), Windows 2003
  • Browser(s):
    Internet Explorer 5.5, Internet Explorer 6.x, Netscape 6.2x, Netscape 7, Mozilla 1.4+
  • JRE version(s):
    1.5.0


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

This process downloads an IFTW (Install From The Web) executable program file (e.g., jre-1_5_0_(version)-windows-i586-p-iftw.exe, appx. 237KB size) and requires minimum user intervention. When you run this program, it fetches all the required files from the web. Hence you must remain connected to the Internet during the installation.

The installer "unpacks" the files needed to continue. A dialog box tracks this process, which takes less than a minute. After briefly displaying a Java logo splash screen, the installer presents the license agreement.

The installer 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.

After ensuring that the Typical setup is selected, click the Next button to continue with the installation.

If Internet Explorer is set as the default browser on your system, then the Java Runtime Environment 5.0 Update 10 – Google Programs dialog box will appear. By default Google Toolbar for Internet Explorer is checked. Click Next button. This will start installing selected programs features including the JRE on your system.
Note: You can choose to install or ignore this useful additional program by checking or unchecking the check box.

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