How to integrate Hibernate and GWT

[Dessorry]

Hi,
I'm trying to build my first GWT application; i would read data from a
database and display it on a simple gwt page.
I create in Eclipse my Web Dynamic Project.
I put my POJO class in mypackage.server and the class with entrypoint
in mypackage.client.
I create a new GWT Remote Service with Eclipse.
Now where must i put the hibernate code to access database?
p.s.in mypackage.server there are hibernate.cfg.xml and pojo.hbm.xml

thanks

Hi there,

Try searching the group there have been many posts discussing
Hibernate and GWT and how to implement them together.

Hi Dessorry,

In terms of where to put your Hibernate code, you're most likely to get useful replies and information on the Hibernate site and discussion forum:

Hibernate homepage:
http://www.hibernate.org/

About using your Hibernate objects in GWT - as you will discover by searching threads in this forum about the subject, you normally can't use Hibernate objects directly in GWT RPC because of the types used in Hibernate that aren't supported by GWT's emulated JRE. However, you can always create data transfer objects that mirror your Hibernate objects. These are regular POJOs that obey the constraints of the emulated JRE. In addition to this and other techniques you might find in a group search, you can also use the Gilead library which is designed for the purpose of integrating Hibernate with GWT.

Chances are that since you're just getting started out with GWT, there are probably more than a few terms in the preceding paragraph that might have you scratching your head. Check out the links below for more info and feel free to post back if you have an additional questions.

Hope that helps,

I have done a few tutorial on integrating the two technologies with
Spring also for a true web app:
