I think that example is flawed. I know from looking at the code, the query
parser needs the "AS some.java.ClassName" clause to parse the query and
interpret its results correctly. Castor doesn't give you access to the raw
resultset. It binds the results to objects and returns those objects.

The basic unit of work for Castor is an object. Normally one row in a table
(or possibly multiple tables) equates to an instance of an object. One field
in a table is kind of meaningless to Castor without an object/class binding.

I think you might be bumping into how Castor retrieves parent-child related
objects. AFAIK, Castor uses outer joins to put all the necessary data into a
single result set. Other people have reported similar issues when reading
back large numbers of related objects.
Ultimately, I think the fix is

I've added a new callback interface into Castor to allow Castor-managed

The interface looks like this:

On my project, we've done something very similar. We use two separate Castor
transactions. One to update the collections (which we do in a quasi-manual
way) and a another transaction to persist the core object. We were never
able to fully resolve all of the locking conflicts we had otherwise.

However, that can lead to "interesting" transaction and locking issues
when trying to do an update.

I think Castor uses URLs to locate the config files. Couldn't you put the
files in a "conf" directory inside your webapp directory? Like this:

Then Castor can load it from the network.
