Java (Applets) in Fedora 18

After some applets wouldn't run in either Chrome or Firefox on my Fedora 18 system, it was time for some investigation.
First I tried installing Oracle Java as some applets might be requiring it explicitely.

Oracle Java

Download Java from here. Follow the instructions for installing, from here.
Then, open "about:plugins" in your browser and check if the Java plugin is displayed there.

Verify Java installation here. Test applet support here or on JavaTester.
Remove old versions, as specified here.

While I first installed 32-bit version of Java, as suggested on Oracle's site, this is not correct. The proper version to install, even for applet support, is 64-bit, if on 64-bit system. After installing 64-bit version and setting it to be the active one, using 'alternatives', applets worked in both browsers!
