Java Browser Games

[elohssa]

For some reason when I try to load Java games in the browser they fail to load and the screen stays gray for a few seconds and then the window closes and I am taken to the error page for that website. Any ideas or suggestions? I am running Ubuntu 10.10.

Thanks

Sorry to ask the obvious, but do you have java installed? Go to the software center and make sure you have "OpenJDK Java 6" and IcedTea installed. If thats already the case, please give us an example of a java game thats not working.

Do the following, this will tell us if you're using OpenJDK or Sun (Oracle) Java:

Click Applications -> Accessories -> Terminal

Type the following and press enter:

update-alternatives --config java

EDIT: Paste the results back here. I want to assume its due to not having sun java or not having sun java set

Experiencing a similar problem, where in http://www.bundesliga.de/de/manager/index.php, after logging in, click Hier geht's zum Spiel and then there is a link to Stadion, which starts the simulation of the football game your team played (it's a football manager game).
They recommend to have just Sun Java installed, which i have ("There is only one alternative in link group java: /usr/lib/jvm/java-6-sun/jre/bin/java
Nothing to configure."); however, on my computer, the starting of the Java applet hangs eventually.
The Java console reports:
