Comment on my question.. Ive been having a read,
It seems if you do not specify a factory, tomcats "default factory is used"
- org.apache.naming.factory.DbcpDataSourceFactory
If correct, is it a good idea to go with this ?

Please respond to

All,
I have implemented a connection pool (oracle 9i database) on websphere and
want to move it to Tomcat.. well, i kind of have, but want to run my
observations past the group first.
I ran a test, whereby a class with a main method created several threads,
each making URL requests of the webapplication. I monitored the
connections in Websphere. As I would expect the pool never went over the
max connections (10), and the test averaged a peak of about 7 connections.
Basically, the only change I had to make to move this to Tomcat was change
the way the initial context lookup was carried out.
On Tomcat, I ran exactly the same test, but the most connections I saw at
any given time was 3. Maybe tomcats connection pool is clever, I dont
know, but the thing that has me worried is that in order to get the Tomcat
version to work, I had to remove the following from the server.xml file :
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
I tried putting commons-dbcp.jar into my common/lib folder, which does
contain the class specified, but i get a noclassdeffounderror on :
org/apache/commons/pool/impl/GenericObjectPool
So, at the moment, without this factory, is the app pooling connections at
all ? Is it better that I get the factory mentioned above working ? If so,
how ?
Thanks
Med
