Database connection pooling errors in Tomcat 5.5.17

[David Smith <dns4 (at) cornell.edu>]

Is the driver in exactly one place -- $TOMCAT_HOME/common/lib?  This is 
the only place the driver is documented to work from.  If the jar file 
is in multiple places it can cause classloader issues.  Related to that, 
also check it isn't in any classpath or the JVM endorsed folder.

Did you restart tomcat between attempts?

As I recall, all JDBC drivers return a more or less generic 
java.sql.Connection object so compatibility with the DBCP based pool is 
a non-issue.
