Ben,
I have just completed a project which allows users to query certain stock
quote information. Rather than perform the query every time I get a request,
I start a background thread in the init() method of the servlet which
queries the Wall Street server every 15 minutes and builds a set of
stockQuote objects. In the doGet() method of the servlet a simple
StockThread.getQuotes() method is called to do a synchronized read of the
quote Hashtable. It has worked quite well and makes for a very low resource
load application.
