Jpa table strategy - how to get the primary key
While it's much more common to reference an entity by its primary key, Hibernate also offers NaturalIds. The NaturalId is mapped to a unique column so that each entity can also be uniquely reference any this natural identifier. You even have an API for retrieving entities by the natural identifier. So I think it's much more elegant to use the natural id for your task because it's consistent ac

Hibernate Implementation with JPA2.0
The EntityManager is an interface and each JPA provider offers an implementation for it. The Hibernate EntityManager implementation simply delegates all calls to the current running Session. The CRUD operations are backed by EntityManager methods: persist merge remove createQuery

Grails 2.4.4 + searchable:0.6.9 runtime issues
I don't think the searchable plugin works with Hibernate 4, but you haven't declared a dependency on any version of Hibernate, which definitely won't work. In my Grails 2.4.4 app, I use the searchable with the following version of the Hibernate plugin plugins { runtime ':hibernate:3.6.10.18' // other plugins }

tomee with hibernate 3
When I started server next day to look into the issue, it was complaining about missing antlr jar file. I added antlr jar file to tomee lib folder, then Hibernate configuration is working without any issues. I am not sure why it wasn't showing missing antlr exception before, It was throwing above posted exception.

JPA association without foreign key
The fact that ConstraintMode.NO_CONSTRAINT is ignored looks like a bug in Hibernate 4 due to be fixed in 5. https://hibernate.atlassian.net/browse/HHH-8805 The comments on that and indeed this post here: Multiple relationships with single mapping table without generating foreign keys by Hibernate suggest adding the deprecated (hibernate rather than JPA) annotation @ForeignKey( name = "none" )

Your application may be hold Connections open rather than returning them promptly to the pool. To test this, try setting unreturnedConnectionTimeout and debugUnreturnedConnectionStackTraces. See here for details. Then check your logs. If your Connections time-out as unreturned, see the logged stack traces of the codepath by which the Connections were open, and modify your application code to clo

DML operations through JPA criteria/JPQL and JPA cache
The DML operations are directly executed against the database, therefore bypassing the first level cache dirty checking emchanism. Neither Interceptors nor Event Listeners nor JPA PostUpdate hooks are going to be triggered, since updates are not generated by the Hibernate action queue mechanism. The AUTO flush is only triggered for HQL/Criteria queries and not for native ones, so you'd better fl

How to add another table when comparing tables using criteria?
As far as I know, Hibernate Criteria doesn't support theta-style joins. So you can use an HQL query instead: List<Object[]> properties = session.createQuery( "select e.name, u.name from Employee e, Users u where e.empCd = u.empCd") .list();

how to cast query.list() result objects to another object?
Your query returns array of fields for Order so you cannot cast it to Order directly. Possible solutions: Working with array (for example, if you need just several field) Add addEntity(class) as was pointed @Zeus or rewrite query as 'from Order...'

Hibernate Search. Exclusion from indexing records with specific properties
You can do this by implementing EntityIndexingInterceptor and then define the implentation in your domain class as: @Indexed(interceptor=BookIndexingInterceptor.class) public class Book extends BaseEntity{ Example of implementation is as below: public class BookIndexingInterceptor implements EntityIndexingInterceptor<Book> { @Override public IndexingOverride onAdd(Book

how dirty read works in hibernate
First level cache is not shared across transactions. Except in case of Extended persistence contexts the most common pattern used is that each transaction is associated with a single session/persistence-context and has its own first level cache which is being tracked only for that transaction. Actually "dirty-read" is a property of database transaction and not Hibernate in general. When one tran

grails/hibernate: add pessimistic locking on using creteria
Depending on how you form your query, Hibernate will execute different queries. The way your query is written Hibernate will perform a join - this can be good for performance because it means your joined entities will already be pre-fetched in the 1 query. For locking however this is bad as every joined table would have to be locked and this can have quite an effect on deep hierarchies. Thus your

JPA Persist ManyToOne
Well, you could simplify a bit your code, to have something like this @Transactional public void save(User user, String name) { Hometown hometown = getEntityManager().createQuery("SELECT h FROM Hometown h WHERE h.name = :name", Hometown.class).setParameter("name", name).getSingleResult(); if (hometown == null) { hometown = new Hometown(name); } user.setHometown(hometown);
