Chris,
Thanks for you time. Your response goes a long way to explaining why there is
so little specific information on embedding tomcat.
Really, just as I said. I had convinced myself from several items encountered
on the web that an embedded tomcat instance would not read the standard
conf/*.xml. If I hit any of those pages again I will react (either on the page
or perhaps post here, if that would be appropriate).
TL/DR: at heart I’m struggling with the proper initialization and consumption
of the dbpc2 datasource which I add programmatically and might consider using
the context.xml version. A litany of small issues:
My @Resource(name, type) Datasource ds” doesn’t take (I have several more
attempts planned)
Is that failure logged?
Is context.lookup() expensive?
Is there any configuration available only in xml?
DriverManager is working fine but it that the best access to the DataSource,
which I need to be able to change the current database (in a postgres sense)
