Hi,
I am checking DbStarter and I love the idea.
The thing which I find surprising is this (line 50,51)
conn = DriverManager.getConnection(url, user, password);
servletContext.setAttribute("connection", conn);
This means that when I get a connection from the servletContext, I get
a non-pooled connection, and always the same one is used.
Questions:
- it is safe to access the same connection from multiple threads? How
this works with transactions? what happens if programmers calls
connection.close() after usage (which is the normal case for jdbc
connections) ?
- why not using a servletContext.setAttribute("pool", connectionPool),
which looks more suitable -to me- for a web application?
Am I missing something special that makes this approach valid for H2 ?
(and invalid for all other databases I know of)
Thanks!
L.
