First, I think I speak for thousands in thanking you for your
contributions. Despite the flame wars, I hope you guys and gals know how
much we appreciate your efforts. Second, could you expand on what Tomcat
puts into a pooled connection for javax.sql.DataSource?
I have been using Postgresql and getting a pooled connection with JBoss and
Tomcat and really do not understand what the "hay" is going on. Is that
from JBoss? I am not getting a pooled connection from Postgresql, even
though I though I was. I so far have just been using Tomcat 3.2.3, I think
it is, and JBoss and am using a standalone application thus far with
Tomcat. But, I definely am getting a pooled connection according to "ps
aux" on my box. I am getting an initial pool of five conncetions, I
think. Maybe six.
Thanx,

Yah, my mistake. I thought they did because I was getting a pool with
Tomcat 3.2.3 and JBoss.
mea culpa, mea maxima culpa.

I am not 100% sure, but I am pretty sure that the PostgreSQL (7.1.2) JDBC
driver does not yet support Pooled DataSource connections.
That is what they have said on the PgSql JDBC list, but please correct me if
I am wrong as we would love to use pooled datasource connections..
I believe Postgres 7.2 (& JDBC driver) might support it...
