hibernate 调用存储过程问题~~~急~~~

Question

报的错：
org.hibernate.HibernateException: Errors in named queries: getUser at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:338) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1176) at hibernatecall.MainTest.main(MainTest.java:16)Exception in thread "main" 
我的配置文件:<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="hibernatecall.UserTable" table="usertable">
<id name="id" column="id">
<generator class="increment"/>
</id>
<property name="name" column="name" type="string" not-null="true"/>
<property name="comaddress" column="comaddress" type="string" not-null="true"/>
<property name="famaddress" column="famaddress" type="string" not-null="true"/>
</class>
  <sql-query name="getUser" callable="true">
<return alias="user" class="hibernateCall.UserTable">
<return-property name="name" column="name"/>
<return-property name="comaddress" column="comaddress"/>
<return-property name="famaddress" column="famaddress"/>
</return>
{call test()}
</sql-query>

</hibernate-mapping>
存储过程:
create proc test
as
    select * from  usertable
请问这个是什么错误 怎么解决
