org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed

Yes, you tried to get data that wasn't loaded yet, and you did not have a session open so that Hibernate could get a Connection to the database.

You can only load data into objects when you are within a Session.

Mark

you might be using lazy="true" in hbm and then try to use that object. You can change it to false but then performance may take a hit

my DAO method code is as follows

Query result = createQuery("select timeOfOp,operation,callerFromNumber,callerToNumber from LogsData where timeOfOp >= '"+startDate+"' and timeOfOp <= '"+endDate+"' order by timeOfOp");
List list =result.list();
logger.infoLog("*******Size of List ="+list.size());
Iterator iterator = list.iterator();
LogsData logsData=null;
while(iterator.hasNext()) {
logsData=new LogsData();
logsData = (LogsData)iterator.next();
logsDataList.add(logsData);
}
logger.infoLog("results size="+logsDataList.size());
closeSession();
return logsDataList;

As Mark said, you may be trying to do all this outside of a Session.
I see a method for closing the Session, but where was it created?

Hi Edvin
session was created in superclass which has createQuery method.

In a case like this, with the relevant code hidden within a framework� Not to exclude that some Rancher would take the challenge and dig into everything, but you'll find a bigger audience if you refactor the code into standard Hibernate usage, as in most books and online examples. And it is not rare to get the problem resolved in the process

.
Hope this helps.
