JDBC pooling is pretty standard in containers these days, Tomcat
included. ;) The code side of this picture is pretty portable: look up a
DataSource via JNDI, use that to fetch connections.  The configuration
side is container-specific.  Tomcat has excellent docs on this at the
website.

If inter-container portability is a great concern (e.g. you sell your
app to external clients), you could also manage the pool yourself using
the commons-dbcp package.
