I should have stated the design parameters more clearly: the reason for revisiting
this app is two-fold - (1) eliminate multiple processes spawned by CGI and (2)
eliminate a socket call for the the quote data for every HTTP request of the homepage.
I thought of servlet chaining - have one servlet make the network connectin and read
in the data into memory every 10 seconds, while the second servlet continuously
delivers the homepage with the formated data to HTTP requests.
Can a servlet make a call to a CGI script on a remote server and accept the result?

How about option 3 of calling server A call from Java and using a
servlet for the whole process?
