Mat Banik opened SPR-8924 and commented

The following exception is thrown during application context start up. I even tried it with the spring-orm-3.1.0.BUILD-20111214.083151-467.jar file to see if it was fixed but no luck.

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

Mat Banik commented

This is missing dataSource property which should be allowed when since hibernate can use C3P0 configured via following props:

<prop key="hibernate.dialect">${db.dialect}</prop>
<prop key="hibernate.connection.driver_class">${jdbc.driverClass}</prop>
<prop key="hibernate.connection.url">${jdbc.url}</prop>
<prop key="hibernate.connection.username">${env.jdbc.user}</prop>
<prop key="hibernate.connection.password">${env.jdbc.password}</prop>
<prop key="hibernate.c3p0.min_size">5</prop>
<prop key="hibernate.c3p0.max_size">20</prop>
<prop key="hibernate.c3p0.timeout">1800</prop>
<prop key="hibernate.c3p0.max_statements">50</prop>
