I'm getting a 'No thread-bound request found' error in my web app and hoping to get some help. I'm trying to use struts2 + spring + hibernate, and use spring to manage the hibernate session factory, and inject hibernate sessions into my struts actions. I hope that made sense. When the app starts up, there are no errors, but when i make t...
Hi everyone I think i'm missing something fundamental about how Hibernate works, specifically with lazy loading. My problem is debugging, as I'm not sure if this is a Hibernate problem or a Spring problem in disguise. I thought I would ask here before doing some major refactoring. I have two Entities. One holds a collection of the ...
Hi All, I have been using hibernate with Springs where i don't get to use getSession() or getCurrentSession() as the Spring container manages it.

If you have a call in a Dao method like (pseudo code): return ..getHibernateTemplate( get by id ); Now say that entity has a lazy-loaded collection. Once you return from your Dao using the hibernateTemplate helper method, how come the session stays in scope and allows you to lazy-load a collection? Is the session initialized and comm...

I have a problem when I try to instantiate Hibernate and connect with a MySQL database (see error message below). Curiously enough the connection works fine using the exact same hibernate.cfg.xml file when running Junit tests but it refuses to work when run from Tomcat... I am starting to run out of ideas. Any clues or tip where to l...
I am trying to use validation with Spring 3.x. I have annotated a method field with @Valid, added <mvc:annotation-driven/> to my common.xml, and added Hibernate-Validator.jar in the lib/ dir, but I keep getting this message: "Hibernate validator not found: ignoring". Am I missing something? [Version:15] Hibernate Annotations 3.4.0.G...
I have been learning Hibernate for the past few weeks, I have gotten most of what I learned to work but have a question on the efficiency of a One-to-Many mapping. It works, but I am pretty sure that it could be tweaked quite a bit. When saving, I notice that there are three queries that get executed, an insert for the "Parent" object, a...
As a new Hibernate user, I have heard that a good pattern for adding some helper methods to generated classes is to add them in a subclass. For example: // generated via Hibernate mapping file public class GeneratedClass { long id; String someValue; // etc, etc. } // my own class with pretty printing method public class MyGener...
Hi, the validate function of the Hibernate Validator seems to be buggy (version hibernate-validator-4.0.2.GA.jar). Do I maybe miss a dependency? Part of my stack trace: java.lang.NoSuchMethodError: javax.persistence.Persistence.getPersistenceUtil()Ljavax/persistence/PersistenceUtil; at org.hibernate.validator.engine.resolver.JP...

Given a representation of database tables where two entities are connected through a join table, is it possible to sort on the other entity specifying the sort order somehow through annotations? Consider, roughly, the following database tables: actor ( id, name ) credit ( actorId, movieId, roleName ) movie ( id, title, year ) And hi...
I'm building a web application using Spring framework and Hibernate with annotation and get stuck with a simple mapping between two entities. I'm trying to create a many-to-many relationship between User and Course. I followed one of the Hibernate tutorials and my implementation is as follows: User class: @Entity @Table(name="USER") ...
looking forward to hear opinion from you all. do you think just use compass and enabled caching in compass is enough and thus no need to use hibernate second level cache? i even heard compass support memcached. in that case no point to use hibernate second level cache do you all use compass and still enable hibernate 2nd level cache on...
