In fact the EntityManager.persist() method (way I could intercept a set of JPA calls without touching any others like Entity classes ). Thus I wanted to have my own provider which will be like MyProvider extends org.apache.openjpa.presist.PersistenceProviderImpl and provide my own entity manager factory and then I can provide my EntityManager which will again will (hoping) to extend default openjpa EntityManager classes. Please find my persistence.xml file [1] So I had come configuration issues and now I am getting this. Can you please provide any solution for this. org.apache.openjpa.persistence.ArgumentException: A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName property.
