Code between sessionFactory.openSession() and session.close():
Be gentle with me as I am new, have read the docs and just need clarification.

I have an object: Run this object has a number of params to include several other objects. One of those I call Status. I have a get and set for the status in the Run.java. I define the fields in the Run.hbm.java with <many-to-one name="status" column="stausID" cascade="all"/>

I get a bit confused on the many naming so what I want is that A run has A status but that Status may belong to many other runs. In the Run.java I am trying to add the status like this:

public void addStatus(Status statusObj)
{
this.getStatus().add(statusObj);
}

In my business method:
I do:
Run run = new Run();
Status status = new Status();
status.setStatus("NONE");
run.addStatus(status);

I can't compile b/c if can not resolve the this.getStatus().add(..); Am I traveling down the right path here? What am I missing? I can't find where the method .add() is defined? I found this in an example and it is not explicitly defined anywhere there either. I thought it might be a Java method but can't seem to find one for the Object class? Any help?

On a side note, is there a better way to do this? I have a number of instances where this scenario occur. I have objects with relationships to other objects. Thanks.

Can't resolve: this.getStatus().add(statusObj);

Name and version of the database you are using:
Sybase ASE 12.5.5

Debug level Hibernate log excerpt:

It looks like you're missing a Collection (like Set for instance) called "status". "add()" would generally indicate that kind of thing.

One other note, not that it has anything to do with your posted problem. Don't do this:


The "this" really shouldn't be there. Just use:

First, you don't want cascade="all" because when you save or delete a Run object, you don't want to add/delete the Status object.

If a single status can belong to more than 1 Run, then it would be assumed that this reference data already exists.


Second, since there is only 1 Status, you're not adding it, your assigning it.



and your business method looks like this:

Oh yeah. I saw the .add() call and immediately thought of a Collection. Clearly from the mapping this is not the intention. My mistake there.

I'm sticking by my assertion against using "this.method()" calls though.

If I don't want cascade="all" which other option do you suggest? I want the status objects to exist in the db status table but for those to be associated with a run at a particular point. I did get the assignment down though. Thanks
