Java Assistance needed

[DCNoob]

On my machine I am trying to access a website that requires Java to be enabled. If I look in Edit>Preferences>Web Features I see a tick in the boxes beside 'enable Java.' When I go to the website that requires Java, however, I receive a prompt saying Java Runtime Environment is not installed and I need to download it.

What gives and how do I get past this little problem?

TIA

You need to install it: http://www.fedoraforum.org/forum/showthread.php?t=59385

To install Java and to enable it for both java plugins and java applications see the Java section here.

I was actually quite a bit further along that I realized looking through your documentation, but after completing your instructions I am sad to report java still does not work. When I run the java test from Sun's website I get a big red X saying the java applet did not load. I rechecked everything to verify I followed instruction exactly and typed everything correctly and I did, so I am not sure where this leaves me.

If I open the java console I see the following:


----------------------------------------------------
c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message
l: dump classloader list
m: print memory usage
o: trigger logging
p: reload proxy configuration
q: hide console
r: reload policy configuration
s: dump system and deployment properties
t: dump thread list
v: dump thread stack
x: clear classloader cache
0-5: set trace level to <n>

That means the JVM (Java virtual machine) was running, only the applet was borked.
