composite-id + hibernate
hello frnd,
i give more about my prblm....
this is code that i fetch record...(main)
//--
xml_config xConfig = new xml_config();
Criteria cri = session.createCriteria(xml_config.class);
String s="CA";
//Query q = session.createQuery("from xml_config config where config.country_cd='CA'");
cri.add(Restrictions.like("country_cd", s));
cri.add(Restrictions.like("Dtd_version", "1.0"));
List q = cri.list();//error line by eclipse ide
Iterator itr = q.iterator();
ArrayList<String> v = new ArrayList<String>();
while(itr.hasNext())
{
xConfig = (zespl_xml_config)itr.next();
v.add(xConfig.getDtd_FileName());
System.out.println("ICH FLAG "+xConfig.getICHFlag());
System.out.println("Dtd file Name "+xConfig.getDtd_FileName());
}
//-
and this my mapping file
//--
<?xml version="1.0"?>
