Hi,

Please don't mention names in messages ;)  There are a ton of people on
this list who are at least as qualified as I am to answer any
question...

OK.  Personally, I like to use something that exists already rather than
code my own / re-invent the wheel.  But if you like and trust your
implementation, good for you ;)

>How would this interact with Tomcat's pooling ???

It wouldn't.  Tomcat doesn't provide its own connection pooling
implementation, only support for you to tell the server what connection
pooling implementation you wish to use.  The commons-dbcp package and
the Oracle connection cache, and many others, can be used with tomcat.
If your implementation complies with the JDBC interfaces, you should be
able to configure tomcat to use your connection pooling implementation.

In addition, you can define side-by-side pools, e.g. one connection pool
using DBCP, one Oracle.  Run the app using DBCP once, then run it again
using Oracle, for example.  This is a good test as to which one is
better for your specific app.

>What significant advantages does Tomcat pooling has (other than one

That it's 3rd party and you can complain loudly on the lists if you find
a bug in it ;)  You can get support for it, whereas for example with
your custom implementation, if there's a bug no one will be able to help
you...
