hi all
using SLSB to insert new USER to db,
using: CMT ,

ending session with :
session.saveOrUpdate(user)
session.close();

data is stored just fine when application ends
but when jboss restart data is lost....

Can you clarify? You shutdown jboss and see you data persisted in dbms.
But after restart what's in db? old data? is there any activity in between?

Check everything twice, looks incredible...

btw - what do you mean "application ends"? Make sure you see new data in dbms after transaction commited.

first of all thank you very much for your replay
here is the deal ..

jbossRC2+hibernate-2.1.6+hypersonic

i took the eg..../auction example hbm.xml's and classes ,
added a hibernate-xml , ejb interceptors(in standardjboss)

and deployed it in a .HAR like:

----->meta-inf/hibernate-service.xml

-->org
--->hibernate
------->auction
-------->example's hbm's and classes

(by the way didnt specify in hiber'-svc.xml the resources jboss found it in deployment)

deployed the har, the mbean was created -
db tables also created.

used a SLSB, to get the session factory from jndi with initial context.


used a simple console client to get the SLSB ,
in SLSB:

User user = new User();
user.set some stuff......
session.saveOrUpdate(user);
session.close()

after the client finshed i could see in the db console the new values in the user table(though id was 0 );

after jboss was restarted (.har was undeployed and redeployed)
the user table was empty......

i know i should have called the flush() but the data was written so i dont think it got anything to do with it

thank u very very much

but....could it be that because i didnt flush()
when jboss restarted the txn was rolledback?

Not if you saw it in another process (i.e., the db console).

Probably you have SchemaExport set to run on SessionFactory startup/shutdown. Thats the normal reason for seeing this type of behaviour. Check your logs to see if drop table commands were being executed and the schema recreated on startup.


Of course. Thats the whole point of the har deployer. :)

you mean :
hibernate.hbm2ddl.auto ?

Yes, though its called Hbm2ddlAuto on the MBean

If you are using my test stuff, it sets this value to create-drop. Probably not what you want for anything other than a unit test env :)

thanx ......

by the way i wish that every LGPL group will as supporting as u guys .....
