Thats why there was no error in the tomcat > logs, nothing went wrong with Tomcat I'm interested in why you are using c3p0. I often ask people who they are using it and they say "because commons-dbcp is crap" but a) they have been looking at decade-old complaints of DBCP and b) c3p0 doesn't have any production-quality released, yet. So I'm wondering why you are using c3p0 instead of either Tomcat's default DBCP or tomcat-pool which should be higher-performance if you feel like you need that. - -chris > On Tue, Sep 16, 2014 at 12:05 PM, Elias Kopsiaftis > <yemi...@gmail.com> wrote: > >> Hey, >> >> I actually answered my own question.
