I recently installed Ubuntu 12.10, and I just now realized I haven't installed Java on it.
When I was going to, I saw that I already have java installed.
java -version gives me:
OpenJDK Runtime Environment (IcedTea7 2.3.7) (7u15-2.3.7-0ubuntu1~12.10)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
Yet I can't see any applets in Firefox. What's the problem?
