mozilla does not reconize java plugin

Go to tools -> addons -> plugins and verify if icedtea-plugin is installed.
Or open a terminal: ctrl+alt+t
dpkg -l icedtea* | grep ii

Example output:
ii icedtea-plugin 1.1.3-1ubuntu1.1 web browser plugin based on OpenJDK and IcedTea to execute Java applets

Testpage (javascript needs to be enabled to load the applet).

Hope someone can make sence of this have i got java yes no its got me

i have just renstalled ubuntu still cannot get java no plugin also found infomation from last OS on this OS in mozilla that cant be right as wiped the slate clean .Anyway if there anybody out there who can how to get java installed without busting my computer again i would love to hear from you

Reinstalling Ubuntu because mozilla is complaining about a missing plugin can be considered as an overreaction.

> The terminal is saying it is not installed

Wrong. The output clearly shows java-plugin as installed.
ii icedtea-plugin

Verify that this java runtime is installed.
openjdk-6-jre

Then try:
sudo update-alternatives --config java

Which website is complaining about missing java?

sorry sam.Thefirst command it said there was no such command ,and the
second command it did nothing ,hope that was helpful louis

The first was the package name only, not a command.
Expected was to find out if the package is installed.
Try this to see if it's installed:
dpkg -l openjdk-6-jre

When java runtime is installed, the second one
sudo update-alternatives --config java

should at least output something like 'only one alternative .... nothing to configure'.
