Trying to run a Java applet. It's for a chess server. Ubuntu does not seem to recognize it.
When i go out to Java it checks the system and informs me that something is wrong with Java on my machine.
Not sure how to fix this.

simply went out to my Chess website ICC, but the applet wouldn't start because it doesn't see Java. I must have that installed.
Thought i had it. went out to the main Java website that checks which version i have and informed me there was "Something wrong with my Java"
that's all there was.

could you please open a terminal and type

java -version

and post the output?

jmh@ubuntu:~$ java -version
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.2) (6b20-1.9.2-0ubuntu2)
OpenJDK Client VM (build 19.0-b09, mixed mode, sharing)

i'm not 100% percent sure but it might be related to that you use the openjdk instead of the oracle version. i know that there are some compability issues between the two versions.

i would suggest to install the oracle version and try it with that one.

do you have a link to the applet so that i can try it with my java version?

if i boot into Windows and use Mozilla i don't have any problems. So it's not the Browser.

for me it works but i have the oracle version installed.

you could also try to install the following package: icedtea6-plugin

the description of that package is: web browser plugin based on OpenJDK and IcedTea to execute Java applets

this might solve you problem.
