Hi there.
First, its great to hear you chose Fedora
- as a fellow fedora usee i say hooray!
Now there are a few things you need to do to make it work correctly.
First make sure that when you type "which java" in the shell it says the right directory. (if not you will compile and run stuff with the default gcj compiler and not the
java you installed).
Now for applets to work in the browser(i assume u use firefox) type the following:
make sure you change in the above line to the correct java version you use(check the path) and to the correct firefox/mozilla version (again check the path).
Basically you create a soft link in the plugins directory to point to the correct java version.
Also, this is a great link for all sorts of fedora questions (got this java solution as well):
here To run jars by clicking do the following:
right-click on the .jar file, choose Properties, choose Open With, click Add, click Use a custom command, and type in xterm -e java -jar
Good luck.
