Update Hibernate

The situation is as follows, when you put the <property name="hibernate.hbm2ddl.auto" value="update"/> property, nothing else works, no query works anymore. the log always ends with

: jul 27, 2017 8:28:18 PM org.hibernate.resource.transaction.backend.jdbc.internal.DdlTransactionIsolatorNonJtaImpl getIsolatedConnection
INFO: HHH10001501: Connection obtained from JdbcConnectionAccess [org.hibernate.engine.jdbc.env.internal.JdbcEnvironmentInitiator$ConnectionProviderJdbcConnectionAccess@6974a715] for (non-JTA) DDL execution was not in auto-commit mode; the Connection 'local transaction' will be committed and the Connection will be set into auto-commit mode.

If I remove this property from update, I can do queries normally, but generate tables, not ... I can not generate tables and I need to generate them from Hibernate.

This is my persistence.xml :
