Hello,
Your suggestion is very interesting.
Nevertheless, I have a small doubt you will probably erase quickly...
When you register you EJB to the Timer Service (through the
"TimerService.create" method call), the timer service receives a TimableEJB
reference. Is this reference the one of the E
You can put as many threads as you want into an outside client.

May be Jboss store some context information in the thread context: if you
start a thread, these information are missing. Starting a thread in the EJB
container is *illegal*.
If you need to call an EJB method time to time, on a regular basis, you
cannot create a Thread in the EJB container
It's in the specs. They're really worth reading. See ejb 1.1 specs at
section 18.1.2

Ashish,
The EJB container manages several resources as a service to ease the programming
burden associated with creating these business objects (EJBs). One of those resources
is threads. By attempting to create your own worker threads, you circumvent the
container's management of these resou
You don't want threads on the server for the very simple reason, it mucks up
the app server. For more detail you can read the spec or orielly's ejb book.
To do what you want, requires something along the lines of job scheduling. You
can read about it at

We do this in weblogic using weblogic startup classes.
We do this in websphere using a generic server.
These options are both proprietary and thus sucky.
I believe JBoss will allow you to do this us

Orion has a file ('orion-ejb-jar.xml' I think) that allows you to specify
the table that an entity bean uses. If you define the attribute 'table' for
your definition, you will get the behavior you desire.

In the Pet store, for every entity bean they define, there is a value object
holder. For example, there is an Order (the ejb) and the OrderModel.
What I have a problem with is the immense amount of code duplicity. If my
Order object has 20 attributes, then I have to define the same 20 attribute

You need to commit the transaction when you exit from

Hi,
as I understand the specification, it is up to the container to synchronize
existing entity bean instances with the DB, i.e. the bean developer must not
make any assumptions as to when the ejbStore() / ejbLoad() methods are called.
If this is the case, how is consistency preserved if the tab

If you can pass command line arguments to sqlplus to execute a .sql file
(this works with MSSQL's isql/osql), then a quick and dirty solution would
be to just execute sqlplus from your Java application. Look at the JDK docs
for the Runtime class.
