Subject: RE: Tomcat 4.0.x JDBC connection pooling
Thanks Eric!
But with Tomcat 4.0.x I don't have things like MaxActive, MinIdle and other
parameters...
4.0 documentation doesn't tell anything about this.
It seems to me that I have to migrate to 4.1.x to use the pool and such
parameters.

TyrexDataSourceFactory: Cannot create DataSource, Exception
He he, I'd love to move to 4.1.18, but I get the most bizzare problems when
I try to do it.
see http://www.experts-exchange.com/Web/Web_Languages/JSP/Q_20456477.html
for details if you are interested.

For this particular error, the Tomcat classloader documentation would
probably be your best bet.

Subject: Re: JDBC Connection pooling
First, thanks to those that pointed me in the right direction. I just have
one more problem with connection pooling. Now when I request a connection
from the connection pool, I get the following exception:
java.sql.SQLException: No suitable driver
pretty standard exception, not really that

connections a 1000 times takes about 60 seconds using unpooled connections

does Tomcat 4 implement JDBC connection pooling by itself or do i have to
configure TC
Does anyone know if Tomcat supports JDBC connection Pooling similar to
WebSphere?
Any information would be appreciated.

Not that I know of, but if you need a good db connection pool,
look at the one from javaexchange.com
I think its called DBconnectionBroker.
Seems to be better than poolman.

Two projects under Apache provide JDBC Connection pooling:
Turbine
Struts.
I think you can use the one from Turbine outside the framwork without any
problems.

Please, have a look on Turbine at http://java.apache.org
there were a lot of discussions in the related groups
about JDBC connection pooling.
