I don't know if this is right place for this thread, but I'll post it anyway.

I have following problem. When I try to open Java Applet in my Firefox browser I get following statement in upper left corner of the page

cerny.lv.LvApplet will appear below in a Java enabled browser.
but nothing appears below, I've checked if Java was enabled by clicking Edit/Preferences/Content and it is enabled.

I have 3.0.11 version of Firefox and typing java -version in Terminal gives my following output
java version "1.6.0_0"
OpenJDK Runtime Environment (IcedTea6 1.4.1) (6b14-1.4.1-0ubuntu7)
OpenJDK Client VM (build 14.0-b08, mixed mode, sharing)
Can someone help me fixing this problem.

Thx in advance.
