Problem with save

Hibernate version: 2

I have the following code

Code:

Session session2 = HibernateSessionFactory.currentSession();
                  session2.saveOrUpdate("Kunde as k set k.onlinepwd = '" + text_onlinepasswort.getText() +  "' where k.kartennr = " + text_kartennr.getText());

and get the following error

Code:

java.lang.RuntimeException: Unknown entity class: java.lang.String
   at ticketline.WebAccount$1.widgetSelected(WebAccount.java:195)
   at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:89)

Umm... I don't know why there have been 30+ views of this thing and no replies. Anyway, SaveOrUpdate takes an object that you have created or made changes to that you would like add to or update in the database. Use Session.createQuery().

Hey! Thanx for the answer. Unfortunately it seems that I do something wrong, cause nothing is stored in the database when I use the following code:

Code:

                  Session session2 = HibernateSessionFactory.currentSession();
                  session2.createQuery("update Kunde as k set k.onlinepwd = '" + text_onlinepasswort.getText() +  "' where k.kartennr = " + 8);

Doing the same thing in the Database Manager works perfect for me:

Code:

update kunde set kunde.onlinepwd = 'rookie' where kunde.kartennr = 8;

So what do I do wrong in my java code? I have no idea, coz there is no error message. All I can see, that nothing is stored...

Sure, but the API allone often does not help. What I need are examples. And didn't find them anywhere.

Please, help a n00b. :-))))

Man, just read the stupid documentation and copy/paste. Nobody here is going to help you out on a Sunday writing trivial code. We don't know whats wrong with your stuff.

And how do you know that simple copy/paste will help then? Great forum here btw. ... Especially the friendly people answering here. Man, why do you hang round in this forum on Sunday, when you don't wanna help people ...

It has already been told to you .....saveOrUpdate doesn't take a string it takes a persistent object.

You apparently isn't using hibernate as it should be....go read the docs.

I know, and if you look down a few posts, you will see that I don't use it anymore. Now I try it with createQuery which takes strings.

Code:

Session session2 = HibernateSessionFactory.currentSession();
                  session2.createQuery("update Kunde as k set k.onlinepwd = '" + text_onlinepasswort.getText() +  "' where k.kartennr = " + 8);
session2.flush();

And with this code I have no error message, but somehow nothing is stored into the database. And coz there is no error message, I have no idea what's wrong.

Maybe you hibernate insiders know without any error message what I forgot to do or what I've done wrong ...
