我正在嘗試使用Hibernate和JtOpen在iSeries(V7R1)中連接到DB2。我遵循Hibernate文檔並創建了以下內容。當我連接到DB2時,它與HSQLDB協同工作,我面臨着下面的錯誤。Hibernate DB2身份生成錯誤

Hibernate配置:
<!-- Database connection settings -->
<property name="connection.driver_class">com.ibm.as400.access.AS400JDBCDriver</property>
<property name="connection.url">jdbc:as400://myserver:446</property>
<property name="connection.username">uuuuu</property>
<property name="connection.password">xxxxx</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.DB2400Dialect</property>

<property name="hbm2ddl.auto">update</property>
<mapping resource="com/repsrv/infopro/domain/Event.hbm.xml" />

資源配置:
<class name="Event" table="EVENT" schema="mylib">
<id name="id" column="EVENT_ID">
<generator class="sequence" />
</id>
<property name="date" type="timestamp" column="EVENT_DATE" />
<property name="title"/>
</class>
我第一次嘗試創建表和連接。然後我也面臨同樣的問題。我嘗試將發生器更改爲本機,序列和標識。我如何確保hibernate連接到指定的庫(Schema)。
