[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - strange PersistenceException with EJB3:tables cannot be crea

jboss4.2,postgresql7.2,jdk1.6: in persistence.xml,I used: <jta-data-source>java:/PostgresDS</jta-data-source> org.hibernate.ejb.HibernatePersistence create-drop org.hibernate.dialect.PostgreSQLDialect Here I set "hibernate.hbm2ddl.auto" to "create-drop",and in JMX-console I also see this DSN:PostgresDS; and in postgres-ds.xml,it also seems no errors: <local-tx-datasource> <jndi-name>PostgresDS</jndi-name> <connection-url>jdbc:postgresql://127.0.0.1:5432/my</connection-url> <driver-class>org.postgresql.Driver</driver-class> <user-name>postgresql</user-name> 111111 but when I access the entities from JSP,exceptions are thrown: java.sql.BatchUpdateException: insert into tbl_Authors (birthday, levels, name) values (2007-11-08 +00:00:00, 5, wawa) failed LOOK:neither '2007-11-08 +00:00:00' nor 'wawa' are quoted with quotation marks,I think this is wrong.But why? it's generated by hibernate itself,not me! What's more,I login the postgresql database,and there is no tables created automatically either.Why this happens?
