hi,

im having some problems calling a mysql sp. im using spring + hibernate. below are my configs:

spring config:
Code:
<beans>
   
    <!-- JNDI DataSource for J2EE environments -->
    <bean id="basDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
      <property name="jndiName"><value>java:/bigfoot-access</value></property>      
    </bean>
   
   <bean id="basSessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
       <property name="dataSource" ref="basDataSource"/>
      <property name="mappingResources">
            <list>
                <value>com/bigfoot/bas/webapp/hibernate/StoredProcedures.hbm.xml</value>
            </list>
        </property>
      <property name="hibernateProperties">
        <value>hibernate.dialect=org.hibernate.dialect.MySQLDialect</value>
      </property>
   </bean>
      
   <bean id="leavesManager" class="com.bigfoot.bas.webapp.hibernate.impls.LeavesManagerImpl">
       <property name="sessionFactory" ref="basSessionFactory"/>
   </bean>
   
   <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
       <property name="sessionFactory"><ref bean="basSessionFactory"/></property>
   </bean>

   <bean id="leavesManagerDao" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
      <property name="transactionManager"><ref bean="transactionManager"/></property>
      <property name="target"><ref bean="leavesManager"/></property>
      <property name="transactionAttributes">
         <props>
            <prop key="create*">PROPAGATION_REQUIRED</prop>
            <prop key="*">PROPAGATION_REQUIRED</prop>
         </props>
      </property>
   </bean>
   
</beans>



StoredProcedures.hbm.xml

Code:

<hibernate-mapping    package="com.bigfoot.bas.webapp.hibernate">

<sql-query name="getAllDepartments" callable="true">   
   <return-scalar column="id" type="java.lang.Long" />
   <return-scalar column="name" type="java.lang.String"/>
   <return-scalar column="description" type="java.lang.String"/>      
   <return-scalar column="createdBy" type="java.lang.Long"/>      
   <return-scalar column="dateCreated" type="java.sql.Date"/>               
   { call DEPARTMENT_GETALLLIST() } 
</sql-query>
      
</hibernate-mapping>



LeavesManagerImpl
Code:
public Collection getAllDepartment() {
       
        logger.info("calling getAllDepartment");
       
        return this.sessionFactory.getCurrentSession().getNamedQuery("getAllDepartments")
                .setResultTransformer(new AliasToBeanResultTransformer(Department.class)).list();

    }



the error below will be thrown if i call LeavesManagerImpl.getAllDepartment()

Code:
