org.hibernate.ejb.event.EJB3MergeEventListener missing after upgrading from Hibernate 3 to 4.3.9
So it looks like this class (and a lot of the other EJB stuff) has been renamed and moved around. I was able to replace instances of org.hibernate.ejb.event.EJB3MergeEventListener (which was located in the hibernate-entitymanager jar in version 3.6.10) with org.hibernate.event.internal.DefaultMergeEventListener (which is actually located in the hibernate-core jar in version...
Hibernate Query cache invalidation
java,hibernate,jpa,caching,concurrency
The query cache is not useful for write-mostly applications, as you probably figured out yourself. There is no write-through query caching option, so you need to question why you are using this feature in the first place. The entity caching is useful when you plan on changing those entities you’re...
Hibernate Domain Object Generation

When the database schema change you just have to regenerate. For more information see the...

How to call MySQL view in Struts2 or Hibernate
java,mysql,hibernate,java-ee,struts2
You can simply create an Entity, that's mapping the database view: @Entity public class CustInfo { private String custMobile; private String profession; private String companyName; private Double annualIncome; } Make sure you include an @Id in your view as well, if that's an updatable view. Then you can simply use...
Hibernate Search not indexing items from database

Using Hibernate on JSP

Hibernate : Stale state exception
java,spring,hibernate,spring-mvc,transactions
The reason for the exception is that you were loading a GroupCanvas before and this has a reference to the GroupSection. Then you delete the GroupSection but when the transaction commits GroupCanvas still holds a reference to the deleted GroupSection and you get the StaleStateException. As you saw, deleting the...
Hibernate dynamic entity model
I managed to solve the problem. The main point is that, when using EntityManagerFactory (the JPA API), the hibernate persistence provider only reads the persistence.xml configuration files and loads the persistence units that are specified therein. However, using a hibernate API configuration, hibernate does not read the persistence.xml files, so...
How to know an object has changed compared to database
java,hibernate,jpa,playframework,playframework-1.x

Blocking Updating or Inserting an Entity when using Cascade in Hibernate

Hibernate's bidirectional OneToOne relationship not working within the same class
java,hibernate,jpa,hibernate-mapping

what is gradle missing to map hibernate?
I think the problem is not really with gradle. It's with the fact that the JPA spec stupidly requires that the classes of the entities are in the same jar/directory as the persistence.xml file. And since Gradle doesn't store the "compiled" resources in the same output directory as the compiled...
how to return two lists from controller class in spring mvc

Optimistic locking not throwing exception when manually setting version field
Unfortunately, (at least for Hibernate) changing the @Version field manually is not going to make it another "version". i.e. Optimistic concurrency checking is done against the version value retrieved when entity is read, not the version field of entity when it is updated. e.g. This will work Foo foo =...
Spring-MVC, Hibernate : Creating DTO objects from Domain objects

How to write a custom CrudRepository method(@Query) to filter the result in my case
java,mysql,spring,hibernate,spring-data-jpa
You need to add @Param annotation to the method variable name so that you can refer it in your query. Code you have written is absolutely fine. In case you need access to EntityManager, then you will need a custom repository. @Query("from Auction a join a.category c where c.name=:categoryName") public...

DTOs and entities which implements the same interface
java,android,spring,hibernate,jpa

JPA - how to prevent an unnecessary join while querying many to many relationships
java,hibernate,jpa,pagination,spring-data
Only way I can see is to map an entity to the join table and replace the many-to-many Product<>Category with one-to-many relationships pointing to this new entity from both Product and Category. Such a change would actually be in line with Hibernate best practices: https://docs.jboss.org/hibernate/orm/3.3/reference/en/html/best-practices.html Do not use exotic association...

Unidirection OnetoOne mapping foreign primary key is not generating in child table

How to avoid Hibernate Validator ConstraintDeclarationException?

To answer your first question. The behavior is specified in the Bean Validation specification section 4.5.5. Method constraints in inheritance hierarchies. Basically the rule is that a method's preconditions (as represented by parameter constraints) must not be strengthened in sub types. This is the so called Liskov substitution principle. To...
Set LocalDateTime to autogenerate with hibernate 4.3.10

Why is my Set variable throwing error when doing a many-many query?
java,spring,hibernate,jsp,spring-mvc
EDIT: In order to have a Many-to-Many mapping between the two entities you have to specify this mapping in the two sides of the relation, and that's what you are missing here because you haven't declared a collection of CustomerCategory in your Advertisement class so you have to add it,...

Cache inconsistency - Entity not always persisted in cached Collection
java,hibernate,jpa,caching,ehcache
The Hibernate Collection Cache always invalidates existing entries and both the Entity and the Collection caches are sharing the same AbstractReadWriteEhcacheAccessStrategy, so a soft-lock is acquired when updating data. Because you are using a unidirectional one-to-many association, you will end up with a Validation table and a Step_validation link table...
Is possible do not fetch eager relation in JPA?

javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated while executing Automatic Bean Validation on event:'prePersist'
hibernate,jpa,eclipselink,bean-validation,jsr303

Try this instead and see if it works: @Version @Basic(optional = false) @NotNull @Column(name = "row_version", nullable = false) private Long...
