i also asked for help from the tomcat-users list, and we narrowed my problem
down to (surprise) dbcp problems.
we are getting a ton of these errors in our catalina.out and i could use
help in fixing it.
i know they are related to our connection pooling, but not what to do to
fix. my understanding of the underlying mechanics of connection pooling is
somewhat limited, though i have subscribed to this list to remedy that if
possible.
i am using a try / catch / finally block to close EVERY connection in my
code. i mean 100%. but i think i am still seeing leaks.
thanks,
barclay
