I want to use c3p0 for connection pooling but I need the properties for configuring it, could someone provide me with some good default settings I can use in my hibernate.properties file to config c3p0 in a web-enviroment?

im using the values in the default hibernate.properties file:

hibernate.c3p0.max_size 2
hibernate.c3p0.min_size 2
hibernate.c3p0.timeout 5000
hibernate.c3p0.max_statements 100
hibernate.c3p0.validate false

are these good enough for a web-enviroment?

I would increase max size to a more appropriate value. I have no experience but 10 (or more ?) will be better than 2

i increased it to 15, 2 did seem like it was low

Actually, do some load tests with your app, with these values. Have a look at the DB CPU/Mem, App server CPU/Mem, etc. And change parameters one by one, you'll see the best real life parameter. It will take you 1 or 2 days (including building the functional case), and you'll be much more confident.
