the entity manager is recreating the tables

Question

My problem is with the entity manager every time i excute my application it drops tables and the creates them. I want to retrive data from the data base so how to prevent it from creating new tables? thanks

Answer 1

For hibernate, set your hibernate.hbm2ddl.auto propery in persistence.xml to validate.

For eclipselink, use the eclipselink.ddl-generation property to NONE .

This will prevent the EntityManager from dropping the schema with every execution.
