i have a set in sysuser table mapping files.

<set name="usertofunc" table="USERTOFUNC" lazy="true" inverse="true" outer-join="true">
<key column="EMPSEQNO"/>



<composite-element class="com.capinfo.ems.login.dao.hibernate.Usertofunc">
<many-to-one name="sysmenu" class="com.capinfo.ems.login.dao.hibernate.Sysmenu" column="FUNCID" outer-join="auto"/>

<property column="SDATE" length="7" name="sdate" type="java.util.Date"/>
<property column="EDATE" length="7" name="edate" type="java.util.Date"/>
</composite-element>

</set>

it goes well but when i query the data
select elements(sysuser.usertofunc) from .Sysuser sysuser where sysuser.empname=:empname

the code is:
List list=sdi.getFuncByName(sysuserbyid.getEmpname());
Iterator iter=list.iterator();
while(iter.hasNext()) {
Usertofunc uf=(Usertofunc) iter.next();
System.out.println(uf.getFuncid());
}
it is no exception but can not get the data
