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.

Click Tools and then Internet Options
Select the Security tab, and select the Custom Level button
Scroll down to Scripting of Java applets
Make sure the Enable radio button is checked
Click OK to save your preference

Chrome
Enter about:plugins in the search field.
In the Plug-ins list, look for Java and check whether Java is enabled (if the Disable link appears, Java is already enabled)

(Optional) Check the Always allowed box to stop additional Chrome warnings when running Java content
