我来为楼主回答一下：
【错误原因】
根据错误的异常信息，我觉得错误在于在.hbm.xml中没指明数据源catalog，比如在配置中可以这样写：
<hibernate-mapping>
<class name="org.hibernate.Order" table="order" catalog="mysql">
<id name="oid" type="java.lang.Integer">
<column name="oid" />
<generator class="native" />
</id>
<property name="oname" type="java.lang.String">
<column name="oname" length="200" />
</property>
<many-to-one name="custmer" class="org.hibernate.Custmer" column="cid" ></many-to-one>
</class>
</hibernate-mapping>

在class标签中加上属性catalog="mysql"后你在试一试，这里数据源用什么改什么，应该就会正确，希望我的回答能对楼主有所帮助！

org.hibernate.exception.SQLGrammarException
说明你写的操作数据库的sql语句有错误，你好好的检查的操作数据库代码
could not insert: [mrmw
