I have given up on Orion (support), completely. When I got to know
Orion, I was very
excited with the EJB 2.0 preview, very good performance etc. Of course,
like most
of you I was disappointed with the documentation, but that was no excuse
not
to try the software.
I was generally happy with
What you want to do is provide your own orion-ejb-jar.xml. place it in
your XXX-ejb.jar under orion/orion-ejb-jar.xml
It will get copied at deployment time. Orion will fill-in all that is
missing but will start with your own copy. You can
then specify tables and attributes for your CMP mappings.
I completely understand where you're trying to go. However, keep in mind
Entity beans are not meant to hold business rules. They are an interface
to
your physical storage.
We have solved that problem using a facade pattern that basically works
by
shielding the developper from the actual
a...
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/myDS");
So maybe it might not work with the initialApplicationContext??
(although
the console belies that)

Ok folks...
Here's what I have found out. Contrary to what I believed, it seems
the Orion console uses another trick than a DataSource to run SQL
commands on the server: the executeSQL method of the

Hi everyone!

If you select a DataSource, you will see a new panel allowing you to
enter SQL commands that will

Have anyone else seen the problem where the getConnection() returns a
com.evermind.sql.ak type, but ANY operation on that connection such as
getMetaData etc. raises a NullPointerException ?
I am desperate to connect to a JDBC datasource _cleanly_ from the client
side. Is it possible ?

I have unsuccessfully tried to implement CMP using PK classes...
Normal implementation, public fields, overriding of the hash value etc.
Anyone got EJB 2.0, CMP, composite keys PK classes working ?

I'd like to point out that a third table is only needed for a N-M
(many-to-many) relationship.
In the case of a 1-N relationship, simply have a foreign key to the
master table.
For example :
Customer object refers to a Country object
you a Customer will only have one Country object. you do NOT
Has anyone managed to build EJB 2.0 applications using Orion, CMP and
composite primary keys
using a PK class ?
I believe I have followed all recommandations but can't seem to make it
work.

So my personal contribution to the subject must be:
who cares how many tables are used 'back there' ? :)
