I have the following message on a website I go often. I have to press [Run this time] button to use the Java application. [Update plug-in] leads to dead end. Because the Java download site doesn’t provide instruction for Debian.
Java(TM) was blocked because it is out of date.
[Run this time] [ Update plug-in ]

I followed this instruction.

Download Java package right file in Chrome, i.e. jre-7u10-linux-x64.tar.gz.

Move to the Java home directory /usr/lib/jvm.

Extract the Java tarball.
$ sudo tar zxvf ~/Downloads/jre-7u10-linux-x64.tar.gz

Subdirectories in /usr/lib/jvm
jre1.7.0_10 directory is created.

java-1.6.0-openjdk-amd64 -> java-6-openjdk-amd64
drwxr-xr-x 7 root root 4096 Dec 16 19:12 java-6-openjdk-amd64

Make a script file in a directory. Assign new Java directory to JAVA_HOME environment variable. Assign Java plugin file path to the symbolic link line at end of the file.
$ more setup-java-plugin.sh

# Sun Java 7 Update 10 and plugin for google chrome

JAVA_HOME=/usr/lib/jvm/jre1.7.0_10
MOZILLA_HOME=~/.mozilla
mkdir $MOZILLA_HOME/plugins
ln -s $JAVA_HOME/lib/amd64/libnpjp2.so $MOZILLA_HOME/plugins

Execute the script file either sh command or chmod +x and type the file name.
I ran ‘sh ~/bin/setup-java-plugin.sh’

The instruction site will display the Java version in the box. Other sites that complain old plugin will provide Java application services.
