How do I enable Java in my web browser?


This article applies to:
  • Platform(s): Windows 7, Vista, Windows XP, Windows 2000, Windows 2003, Macintosh OS X

SYMPTOMS

Even after installing Java, Applets do not run.


CAUSE

Java is not enabled in the web browser. If Java is already installed but applets do not work, you need to enable Java through your web browser.


SOLUTION

If you recently installed Java, you may need to restart your browser (close all browser windows and re-open), in order for the browser to recognize the installation. In addition, make sure Java content in the browser is enabled through the Java Control Panel.

Follow these instructions to enable Java though your Web browser.
