Hi Euclides,
if you are making a custom connection pool with DBCP, you would get a
better response by mailing their users & developers on the commons
mailing list.

Sounds interesting, but I can't help, sorry. What drives you to write a
custom connection pool anyway? Have you got problems with the commons
implementation?

Adam
