When I'm redeploying a webap with the org.eclipse.jetty.deploy.
ContextDeployer
I see that the old connections are still there. As you can see in in my
jetty-env.xml, I'm using c3po Resource. I discovered this when i was
looking at communication link failures that i suspect are due to
mysql's 8 hour close connection default strategy.
My question is, how do I destroy the c3po connection pool when redeploying?
Kind regards
