Hi David,
Your suggestion solved the problem. I never realized that I had put in a
wrong class for the driver. (I didn't have to do any of the other
suggestions that you'd made in order to make it work). Thanks so much for
spending your time on this and helping me out.
Thanks again!

This tells me a lot: > Caused by: java.sql.SQLException: No suitable
driver
Make sure the driver .jar file is in common/lib and the driverClassName
parameter of your <ResourceParams> element references the correct driver
class (don't use a DataSource class here). In your case, I think that
should be 'com.pointbase.jdbc.jdbcUniversalDriver'. If you move the driver
file into common/lib, restart Tomcat so it can see the jar file.

Hi all,
Tomcat 5.0.28 with Pointbase - Trying to obtain a database connection
from the DataSource.
I saw a zillion places in the web where they've discussed a problem
quite similar to the exception shown below BUT, none exactly like what I'm
experiencing. And by the way, I couldn't even find one case where they
were trying to connect with Pointbase. I followed documentation from all
over the web, but I don't see anything that I could be missing. To
explain, many have complained about null values for class and URL in the
exception message that you see below, but I don't have that problem. What
could be wrong?
I have spent 5 hours trying to fix this.
(It is not even a case of the JDBC driver not being located as I get a
different error message when I remove the JDBC driver .jar files
(pbclient.jar). Pointbase is up and running on port 9092. Funny thing is
the same error message comes up whether Pointbase is running or not.)
Please HELP !!
