Vaadin and Service Builder

Hi there.
Does anyone know (or can supply reference on) how to get hold of Service Builder classes from within Vaadin?
Here is one of my many failing attempts.
Since UserLocalServiceUtil works without problems I expected
Caused by: org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
in line 8 of code above. So Hibernate Session is not bound to this thread. Seems I don't have the appropriate objects (instances) at all. Which brings me to my question: How to get hold of them?
Thank you! And have a nice weekend.
Cheers.
PS: Sorry for displaying such an amount of ignorance. INet couldn't help me here so far.

List<user> clients = UserLocalServiceUtil.getOrganizationUsers(chamberId);
for (User client : clients)
{
try
{
MyEntityPersistence MyEntityPersistence = MyEntityUtil.getPersistence();
List<myentity> myEntities = MyEntityPersistence.findByClientId(client.getUserId());
</myentity></user>
Since UserLocalServiceUtil works without problems I expected
- MyEntityUtil
- MyEntityLocalServiceImpl
- MyEntityPersistenceImpl

Yep, we do this all the time...
Basically in MyEntityLocalServiceImpl, add the method List<MyEntity> findByClientId(long userId) method. This method implementation, since it is part of the plugin providing the service it won't encounter class cast issues.
Upon re-running service builder, the MyEntityLocalServiceUtil class will now have a findByClientId() method that you can use in your Vaadin layer to access the information.

Thanks David.
This and your explanation in the other thread cleared it for me. Thank you for taking some time of your precious weekend.
Cheers
PS: If someone else should ever run into this, after a quick note here, I'll add my lines. It's very basic. You just need to know about the process.
