The parameter property is not mentioned in the Users Guide (yet), but it
is in the JavaDocs.
The parameter here was just the value "select". I call it "task" inside
the Action, to leave the option of passing ?task=select as a query
string. Of course, you could also call it parameter internally, and make
the query string alternative "parameter=select", which would probably be
a better convention:
String parameter = mapping.getParameter();
if (parameter==null) parameter =
request.getParameter("parameter");
