My project is doing its initial database operations through OpenJPA. And it has to perform rest of the operations through JDBC. Data insertion in a table is happening through OpenJPA. But when the same inserted data is queried through JDBC its not available it seems since entire process is a part of single transaction. Is there any way using which we can commit the transaction in between and continue the JDBC operation in a single process.
Instead of creating a new JDBC connection, I tried creating connection like :
EntityManager em = emf.createEntityManager(); broker = (Broker) JPAFacadeHelper.toBroker(em); JDBCStore store = (JDBCStore)broker.getStoreManager(); conn = store.getConnection();
By providing persistence unit name to 'EntityManagerFactory' but it gave me exception like:
