Re: UserTransaction
hi Devid you have to prepare 3 files: 1) a .jar file containig the ejbs classes and the .xml descriptor (under Meta-inf) 2) a .war file containig your jsps, static files, and the web.xml file (under web-inf) 3) a .ear file containing the ejb .jar file the .war file and the application.xml file (under Meta-inf) 4) copy the .ear file under $ORION_HOME/applications 5) start orion hope this helps ciao Paolo David- wrote: hi guys, i m new to ejb and want to develop them using the orion server...could someone explain where do i put up my ejbs and my jsps..i mean what im looking for is a directory pattern...I tried alot of combos but...does not seem to work... thanks in advance David begin:vcard n:;nome x-mozilla-html:FALSE adr:;; version:2.1 email;internet:[EMAIL PROTECTED] fn:nome cognome end:vcard
RE: UserTransaction
I think the easiest way to learn is to use the visual tools that come with orion and create a project with the 'orion specific' directory structure. Use the tool for a little bit to see where it saves the classes, jsps and descriptors. Once you are confortable, put the visual tool away and do it manually (it still has a lot of bugs).

Re: UserTransaction.
Hello Rui,
Currently we do not support getting a UserTransaction reference from an
application client (the specification does not say that clients should have
access to it). We will probably implement it in a future release, but it will
then be Orion specific and not portable to every J2EE server. Also, it's usually
not a good choice to do transaction demarcation on the client.
I would recommend doing the transaction demarcation from a session bean. If you
want to, you can see the session bean as a part of your client logically, just
that it's residing on the server, and you can probably put the kind of logic you
want client transaction demarcation for in the session bean (but since I don't
know exactly what you're using it for, I can't say for sure...)

Karl Avedal

What is the default JNDI name where the UserTransaction is bound for clients
?
Do I have to include it as a resource in my application-client.xml to bind
it to JNDI ?
And how do I configure this ?
thx for the help.

RE: UserTransaction.
Hi Karl,
Well, you're right, as far as I know the specification doesn't say
that this should be implemented, but it doesn't say the opposite
either... and this is a common feature around J2EE servers. So I
really hope that the Orion team implement this one quickly...
I don't understand why the implementation is not going to be portable,
aren't we talking about standard interfaces here ?
Thanks,
Rui Gil

Re: UserTransaction.
Hello Rui, Ok, since you want it, we'll implement it. It's put up as a feature request, so expect it in about a week.

It will not be portable since it's outside the specification of the platform. You're looking somethign up from the environment that the specification isn't saying will be there. That's like relying on System properties that might be there on some platforms, but not on some. You are using a standard interface to access the systerm properties, but they will not always be there. This means that your application will not be "pure J2EE" and work on every J2EE server, but as long as you're ok with that, it's no problem, except for the usual problems of transaction demarcation from the client (network latency making the transactions long, and with many clients, you could get many long transactions going...) Moving your transaction demarcation across the network to the session beans on the server will usually help your application to perform better. Regards, Karl Avedal

Hello,
i have a SessionBean:

ejb-jar.xml: session

when my client calls the create-method, i get following exception:
"Only beans with user-managed transaction can invoke getUserTransaction()"
did i miss something?
