After the latest update Mac OS X Lion, I think that Apple disabled Java applications by default. When I try to run one, I get the following dialog:

If I choose to "Enable" it, how would I disable it later on? Is there any other way to enable this setting besides trying to launch a Java application (i.e. is there some place to manage this setting)?

Use the Java Preferences app (located in the Utilities folder) to manage Java settings (also see this reference).

General steps:

  1. Go to your Utilities folder (either by going to the Applications folder or using the ++U key combo from Finder)
  2. Launch the Java Preferences application
  3. Uncheck the box next to "Enable applet plug-in and Web Start applications"
