Up to now I have assumed that things work as you explained. However opening
new connections is typically a fairly slow business. When programming in C
or Perl one gets used to using the same connection over and over again,
processing transactions in a loop. This does not appear to be possible with
I'm not sure whether this should go into the tutorial, the reference docs
or the WIKI.
It is possible to add any attribute you like to the schema XML; it will be
ignored by the generator scripts. I find this useful in order to add extra
semantics to the schema, which I then pick up in my own xml
Hvae you looked at java.util.Collections? See the methods reverse(), which

a convenient comparator.
Try something like

It is frequently not quite what is wanted. For instance, I want to find all
orphaned objects, so I need to construct a Criteria that is equivalent to
WHERE id NOT IN (SELECT id FROM othertable)
and to use this in a doSelect() or doDelete(). I do not want to construct

I have found a hole in the validation of the schema XML.
I used to have a column FORMULAID, which I removed. However there was

code generated are exactly the same. The effect of this is that the time
