This is my logger configuration:
log4j.logger.org.hibernate.SQL=TRACE, stdout
log4j.logger.org.hibernate.type=TRACE, stdout
but I don't see type bingings
So I tried this
log4j.logger.org.hibernate=TRACE, stdout
to see if I missed something (this shows all hibernate loggers)
and I found out that the org.hibernate.engine.QueryParame...
Hi,
Using hibernate 3.2.4.sp1
I have two entities
User and ContactInfo
A User has a related ContactInfo, relation is unidirectional, i.e. ContactInfo has no idea about the user it belongs to (nor should it as it is reused in other relations)
The User entity has an entity listener preventing other users than the actual user itself t...
I have a complex object graph with JPA connected entities. When I delete the parent the deletions cascade correctly to the children.
Then I instrument the parent class (as to not load eagerly one-to-one relationships) and upon deletion I get referential integrity violation exceptions. Looking at the queries hibernate issues upon flush,...

Processing of a packet involves database transactions, so basically it is like :
Thread:
run () {
try {

fireMessageEvent(data);
...
} catch (Exception e) {
}
}

I have a hibernate entity called Execution. It is created in the beginning of my process and updated at end, indicating how it has finished.
I would like to update a single property of this entity, without causing a select in my database.
Execution execution = entityManager.getReference(Execution.class, executionId);

Hi there,
I don't know why but hibernate tries to cast BigDecimal to one of my columns. This column is definied as Decimal(3,0) in my DB2 DB. So there can't be a BigDecimal.

<key-property name="land" type="int">
<column name="PFIELD1" precision="3"/>

Hi everybody, I hope someone can help me find an answer.
I'm working with a legacy database and I can't change any of the preexisting tables, because other apps depend on them.
I have three main existing tables: A,B,C.
A has a column with reference to B(many to one relation). The problem is that it should have a relation to C not to B...

By default, hbm2ddl spits a ton of output to the console when executing the ant task. I'd like to turn this completely off and simply look at the schema file if something has gone wrong. Anyone know how to do that?

I did all the validations for my actions and when i start tesing no testing was being performed.
I figured out FullHibernate Plugin xml doesn't have the validation interceptor, but defining an interceptor stack with basicStack, hibernateSessionInterceptor and validation interceptors doesn't fix the problem.
Thanks a lot.

I have a Parent class with a List of children. I would like to load the Parent by something other than the id e.g. by name...I am using criteria.setFetchMode("children",FetchMode.JOIN);
and criteria.add(Restrictions.eq("name", name)) to eagerly load all the data for the parent with a unique name. Problem is I get back thousands of result...
I'm working on a web application. Usually at the beginning of a request (through the architecture code), a Hibernate session is opened to work with DB transactions. At the end of the request the session is closed. This works great for all of our transactions, except that in one particular instance, I want to fire a thread from a request....
Hi,
I'm trying to implement a custom validation annotation in Seam.
We have a list of objects, lets call it arrayA, and arrayA is different dependent on today's date.
Next we have an input field stringB, stringB is some value in arrayA going through a transformation function funcC(...).
So basically, we can validate stringB using th...
suppose i have a sequence, called TEST_SEQ
what would be the correct way of selecting its next value ?
this does not work:
select next value for TEST_SEQ
probably because it expects a "FROM" clause.
looking at HSQLDialect.getSequenceNextValString() in hibernate i see this:
"select next value for " + sequenceName + " from dual_" + sequ...
