So not sure if this question should be in here or the EJB 3 section but i can't
seem to find the answer to this if there is one.
I basically have for my named query -
select e from TABLE where column in (:stuff)
... now how do i populate stuff? It wont acccept an array, if i pass a comma
Ok maybe i am just missing it here.
I am trying to create a fairly simple page flow definition. And i am using page
flows because it could eventually get more complicated based on a substance.
But how do i handle error validations?
| page name=loader-information view-id=/loadCollection.xhtml

Thanks yeah i may do that for now.
But it seems like there has to be another easy way. Almost every page has some
kind of validation i need to call itself back on.

If you put it in a JMS queue, the MDB has to pick it up. So do you just have in
the mdb a forward to the next jbpm then?

So with the Seam's version of Interceptors it appears to make the code look
MUCH nicer.
I have 2 questions. I gather i can only do it at the class level, and not the
method level??
Secondly. Inside the annotation itself, can i define it as a Seam component? It
doesnt appear i can because I
There is this one call we have that literally can take 5 - 10 minutes to run

4 years ago i know the pattern was to basically take the request ... send it
into a messageQueue, have the MDB pick it up and work on it.
Couldnt you just put an interceptor on the Entity bean?
or intercept one of seam's interceptors.
Shouldnt be too hard to figure out where it happens at, just throw an exception
in the setter and watch the stack trace

Quick question, you are using @SequenceGenerator @GeneratedValue with a
strategy of Sequence, you are on oracle, and give it a name lets call it

Would you expect for that S_temp to show up in the sequences table in oracle?
