Please TellTheDetails. We can't help you if you don't.

[V Patil]

we are generating POJO classes using My Eclipse.
Table which is not having primary key is autogenerated by eclipse as a composite key while generating POJO files. i.e. a id class is generated
say for eg
DVLMASTER.java
DVLMASTERID.java
AbstractDVLMASTERID.java
AbstractDVLMASTER.java
and the mapping file .

i m using dao file also , in which findbyproperty is present .after using that
i m gettn result count correct, but the value is null.

l_objDoccode = dao1.findByProperty("id.division","MS");

System.out.println("doc code object size is"+l_objDoccode.size());

List DoccdeLst = new ArrayList();

for(int i =0; i<l_objDoccode.size();i++)
{


AccDvlDivMaster l_objAccDvlDivMaster =(AccDvlDivMaster)l_objDoccode.get(i);

l_objDoccode size is 52 .
but null .

What does findByProperty do?

[V Patil]

find by property
is this method

public List findByProperty(String propertyName, Object value) {
log.debug("finding AccDvlMaster instance with property: "
+ propertyName + ", value: " + value);
try {
String queryString = "from AccDvlMaster as model where model."
+ propertyName + "= ?";
Query queryObject = getSession().createQuery(queryString);
queryObject.setParameter(0, value);
return queryObject.list();
} catch (RuntimeException re) {
                        System.out.println("Exception::"+re);
log.error("find by property name failed", re);
throw re;
}
}

which is in DAO class parameters are
propertyName which is column name in pojo class and Object. n e more inform ation req?
