How to enable Java in Ubuntu

Hi,

here is a short recipe how to enable Java applets and the Java console in Ubuntu (and others with the same installation tool set), compiled from a previous contribution and another hint somewhere:

Here is my retype of the application control logic to switch schemas using search paths in postgresql.

class ApplicationController < ActionController::Base

	before_filter :set_account
	after_filter :clear_account

# 1) Point *.example.com in your DNS setup to your server.
#
# 2) Setup an Apache vhost to catch the star pointer:
#
# <VirtualHost *:80>
#   ServerName *.example.com
# </VirtualHost>
#
# 3) Set the current account from the subdomain
class ApplicationController < ActionController::Base
