My story is as follows. I have a java app with hibernate connected to a embedded db(derby). The funny thing was, that my hibernate app printed the uname at start, because i was using slf4j-simple, and so i set my App to use log4j. Hibernate db uname&pass are set in code, using property object. I tried using the same trick on log4j prope...
Hi folks, I try to map a relation for the first time. I have found a lot of ways to go. There are two classes: - Project (Parent) - Application (Child) So one project can have several applications, but one application belongs to just one project.. I constructed them as follows: Project.java import javax.persistence.CascadeType; ...
I have an existing DB schema which I'm trying to ORM'ise with JPA/Hibernate annotations. The schema is designed to allow for clients to assoicate extra information with each row in a table. Rather than using a key-value pattern the existing solution determines the required number of dynamic columns at install time, and alters the table t...
Hi, Hibernate exposes its data model through the Configuration object, where I can access PersistentClass and Property objects. Some of the Property objects describe a relation between two PersistentClass instances. For example, if I have a one-to-many relation between Person and Address in my model, and a many-to-one inverse relation ...
Hi! I have a problem with mapping triple join table as a map with Hibernate using annotations.

Database structure is given strictly from supervisor, so it would be g...

Is it possible to limit the number of rows that are updated using Hibernate/HQL? For instance: Query q = em.createQuery("UPDATE MyObj o Set o.prop = :prop"); q.setParameter("prop", "foo"); q.setMaxResults(myLimit); int res = q.executeUpdate(); if (res > myLimit) { // This is entering here and I don't want it to! } I've been Goog...
I think my Hibernate (3.5.3) Second Level Cache is well configured with EhCache (2.2). At least, I observe following log entries: 20:15:28 DEBUG [net.sf.ehcache.Cache#searchInStoreWithStats] persistence.unit:unitName=#pu-pay.c.u.p.model.ActionCache: persistence.unit:unitName=#pu-pay.c.u.p.model.Action store hit for c.u.p.model.Action#T...

Typically , I use Hibernate's @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) to cache an @Entity class , and it works well. In JPA2 , there's another @Cacheable annotation that seems to be the same functionality with Hibernate's @Cache. To make my entity class independent of hibernate's package , I want to give it a try....

I have a project that compiles and runs completely fine under OS/X, but under Linux an exception is thrown that gives no clue as to what might be the problem.
