Ok, here it goes, I paste the relevant code and and attach the files and
its xdoclet build file.
Here's the exception I get, well, actually, I debugged the jboss
execution and the FacturaLocal object is not null but is not the entity
just created.
It seems to me that it passes the if condition !!!!!! but somehow its
not usefull

Post by Timothy Peter CockleSounds odd as the create should return the entity bean.
Attach the relevant code and build file.
Tim
Hy,
I'm used middlegen to generate code from a database schema, I has
InnoDB tables into a mysql database,
In particular, I have one table with an autoincrement pk field (well,
in fact, all the tables have an autoincrement pk field), wich is
causing me some problems.
This table, has a child table (1 - 0..N Relation) well, thay work
fairly well if you create first one row int he parent table, then you
manage to get its local instance (I call them from a session bean, so
I use the local interfaces), and then insert the childs wioth this
local object in the create call.
The problem arises as, from the client app, the user can create a new
structure (a new parent with new childs) and then I need to create the
parent (this step its ok) an then get this newly created parent and
insert the childs, this second step is what is causing me problems.
First, the aprent create method returns me null, The bean returns a
PKFactura (the table is called Factura) but the method in the
localhome interface (generated with XDoclet using the tgas generated
with middlegen) returns a FacturaLocalHome object, I thinks its ok as
Jbosss deploys it ok and I don't know what the specification says
about this, anyway, as I said the create method returns null, nor the
PK nor the newly created entity.
So, here arises the problem, I have no way to get this entity without
user intervention, as no other field is unique, I dont know the pk the
mysql engine asigned the new parent row.
The only way i think I have to get the pk it with the SELECT
LAST_INSERTED_ID() SQL sentence, I havent tested yet but I'm not sure
* It returns the last inserted autoincrement value on a
connection base, so if Jboss doesn't employ the same
connection to insert the parents and the childs, i wont do, or
if the same connection is used by jboss to insert one parent,
then another parent , then the childs from the first
parent......... it won't do.
In fact I'm not sure about the behaviour of jboss at this point, th
parent and the childs, are inserted in the same method of the wrapper
session bean, maybe, its done into one transaction, and so inside the
same connection.
Well, does anyone knows if the LAST_INSERTED_ID() aproach will
do????????
