Hey Steve, I am getting a Null Pointer Exception and this error in my stacktrace com.mchange.v2.c3p0.impl.C3P0PooledConnectionPool1PooledConnectionResourcePoolManager.acquireResource(C3P0PooledConnectionPool.java:137) If you can help me it would be great. I have added these properties : <property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property> <property name="c3p0.min_size">5</property> <property name="c3p0.max_size">20</property> <property name="c3p0.timeout">1800</property> <property name="c3p0.max_statements">1000</property> and the jar for c3p0 as well.
