From javadoc, Criteria impl is serializable.
A criteria is created from session.
Can I call criteria.list() after the criteria is serialized and then deserialized?

If not, how can use the same criteria in a new session?

Thanks,
dave

Use DetachedCriteria ;)

Code:

DetachedCriteria detCrit = DetachedCriteria.createCriteria(Object.class);

// serialize DetachedCriteria
//------------------------------
// open new session here and deserialize DetachedCriteria

Criteria crit = detCrit.getExecutableCriteria(session);
// etc.

oops.

Code:

DetachedCriteria detCrit = DetachedCriteria.createCriteria(Object.class);

should be:

Code:

DetachedCriteria detCrit = DetachedCriteria.forClass(Object.class);

Thanks, very helpful.

for
DetachedCriteria.forEntityName(String entityName)

What is the entityName? how is it related to forClass(Class clazz)?
Is there a way to check clazz?

Thanks.
