Hi Michael,
Sorry for coming back so late. The re-persisting of the kid when you try to
delete it makes me think you have a cascade-type.all or, in any case, a
cascade-type that includes persist.
Make the cascade-type from parent to kid merge and remove only and from the kid
to parent merge
All session bean implementations have the required @SecurityDomain(theDomain)
annotation.
What does not work is that once somebody has logged in, he can call any session
bean method, even those calling for a role he is not in.
This is in JBoss 4.0.3. This has worked fine before in EJB 2.1.
Heaven knows what DML is. However, it sounds as if it a feature not supported
for your query to be effective. Your query looks fine to me.
To do the same you can use the entity manger to return the child object with id
1 and then do child.setParent(parent);

Yes, I have. Then I did a subjects.clear() No exceptions or anything, but the
student-subject relationship was still there in the relationship table in MySQL.

Hi Mike,
Sometimes you just have to think in database terms. Your kids table has a
foreign key field for the primary key of the table called parent. There is
nothing in the parent table to give any indication of how many kids the
specific parent has.
What this boils down to is this: just

Turn your InheritanceType to SINGLE_TABLE and see if it works.

Yes, as far as I kow you are absolutely right. Use the two one to many
relationships and see your relationship table as a table in its own right.
That is because of the extra fields.

There is a many to many relationship between students and subjects. At the end
of the year this relationship has to be dissolved so new subjects can be
assigned to each student the next year.
I thought it was going to be easy. First, get all the students in a list with
a query. Then loop

I have two classes with composite PKs. The PK classes are annotated with

Student_Test. The PK is called
Sorry, can't help you with the EJBQL. But there is another way you can do
this. You are using the id (PK).
You can do: Assettypes type = entityManager.find(Assettypes.class, id);

|
That will accomplish the same.

Just maybe this may help.
In your case B is A (has access to all methods and fields of A), but A is not

access fields of B through A will not work, although the opposite will.

Hi Johannes,
I looked at your join date - my mistake.
Hibernate is a way to access a database, not a database itself. Before EJB3
there was EJB2.1. That was a notoriously complicated way of using a database.
JBoss then decided to use Hibernate, which was much closer to the present (and

Hi Johannes,
This is a bit late, you may never see this or may have solved the problem.
The problem is: Using dialect: org.hibernate.dialect.HSQLDialect
Set up your persistence.xml to use org.hibernate.dialect.MySQLDialect
That should do it.

Yes, it is possible to use primary keys of any complexity. Some time since I
last did it, so I will be vague.
Your complex primary key must be a single java class with the keys your complex
key is made up of as members. I think the terminology is a Java Data Object,
but I won't stake my life
