Subject Re: Resource Annotation has no effect but JNDI Lookup works (JDBC Resource)

Chris;

This example is not mean that put your database architecture on top of this :) Just shows
that container injects the resource if you use container aware class.


Otherwise stick with JPA :)


Thanks;

While this example appears to work, I might recommend to the reader that
using a JDBC DataSource directly in a servlet should probably be
considered poor architecture. I would recommend putting your
data-fetching logic in a support class, which will be easier to test and
maintain over time.
