我在写User.hbm.xml时这样配置（包是com.hyctl.hibernate.beans，类名未User，对应的表名是user的属性都没错）。
<class name="User" table="user">
<id name="id" column="ID" type="integer">
<generator class="increment"/>
</id>
<property name="username" column="username" type="string" />
<property name="password" column="password" type="string" />
<property name="email" column="email" type="string" />
</class>
但是在跑起来是却出现了以下的异常，什么原因啊？我在另一台机器上是可以跑的，但代码放到另一台机器就不行了。
