Question

I am using spring an Hibernate and here is the Hibernate.properties
The problem is the Connection provider is not changing to c3p0ConnectionProvider even though there are c3p0 settings.THey are just loaded and nothing seems to be done with them.

    hibernate.show_sql=true
hibernate.hbm2ddl.auto=validate
hibernate.c3p0.testConnectionOnCheckin = true
hibernate.c3p0.checkoutTimeout = 0
hibernate.c3p0.acquireIncrement=5
hibernate.c3p0.idleConnectionTestPeriod=3000
hibernate.c3p0.initialPoolSize=10
hibernate.c3p0.maxIdleTime=300
hibernate.c3p0.maxPoolSize=50
hibernate.c3p0.maxStatements=100
hibernate.c3p0.minPoolSize=5
hibernate.c3p0.testConnectionsOnCheckout=true

Here is the stack trace.

Answer 1

Fixed by adding this to the context/persistence.xml

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> 
  <property name="driverClass"><value>com.mysql.jdbc.Driver</value></property> 
  <property name="jdbcUrl"><value>jdbc:mysql://localhost XXX</value>    

 </property> 
  <property name="user"><value>zzz</value></property> 
  <property name="password"><value>xxx</value></property> 
</bean>

I am still not sure why it did not work without com.mchange.v2.c3p0.ComboPooledDataSource.
