Hi
i am insering into table using save() method.
but i am getting this exception.

org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session:

My code:
public void insert(String filePath, String state) throws IOException
{
List stateInfo = parseFile(filePath);

deleteRecords(state);

insertRecords(stateInfo);
}

public void deleteRecords(String state)
{
Session hs = getCurrentSQLServer2000Session();
int noOfRowsDeleted = hs.createQuery(DELETE_RECORDS_BY_STATE_HQL).setString(0,state).executeUpdate();
}


public void insertRecords(List recordsToInsert)
{
Session hs = getCurrentSQLServer2000Session();

for(int i=0;i<recordsToInsert.size();i++)
{
hs.save(recordsToInsert.get(i));
}
}

Stact Trace:

It doesn't look like you are using servlet filters and Open Session in View pattern (http://www.hibernate.org/43.html). How do you manage your session?

Do you have any objects that you are deleting also in the list for Insertions?
If you have already have a object persisted(and also unsaved objects), you should use saveOrUpdate instead of save just to avoid this kind of errors.
