Hello,

If I try to use a c3p0 connection pooling together with Hibernate/JPA the Ejb3Configuration.setDataSource method overwrites the CONNECTION_PROVIDER property. Therefore the ConnectionProviderFactory always creates an instance of type InjectedDataSourceConnectionProvider and not of the expected type C3P0ConnectionProvider.

Does anybody know why I can not create the right ConnectionProvider?
Thanks

My mistake,
Because I use spring configuration which manages the DataSource ( “HotSwappableDatasource“ approach), I have to manage the connection pooling inside my DataSourceFactoryBean.
