Our team develops on Tomcat and deploys on Websphere.

I see in the eBook that the default connection pooling is only suitable for development.

Is this the pooling turned on by the following?
hibernate.connection.pool_size 1
hibernate.statement_cache.size 25

The book reccommends C3P0 pooling:
1. can we use this pooling for development on Tomcat an in production on Websphere?
2. Is it advisable to use it on websphere?
3. Do the C3P0 libararies come with hibernate, or do they need to be downloaded and configured separately?

If you deploy in a managed environment (an application server) you should always use a Datasource.
