Hello David
First, my thanks to you for addressing this issue.
So I will first consider your first reply concering the 0.9.2 approach.
To test this multiple jar / multiple database issue, I will again need
to recreate a second database and the appropriate ejb jar deployment.
Over the next several days I will do some work on this and try to get
this going, and will respond again when I have results to report.
Now, with respect to your 1.0 approach, the stategy you have suggested
below looks fairly staightforward. Yes, it does look like what I am
trying to do. Could you give an loose estimate for when such a
set of experiments would be testable with the 1.0? (Any kind of
estimate, over-estimate, or whatever is fine: I know only too well
that everything takes longer than originally planned.) I would be
interested in testing such a methodology but will have to work it in
with my current development efforts.

Ok, so I am replying to this email twice as I want to discuss some 1.0
stuff in relation to your apps without confusing things (life in 0.9.2
vs. 1.0).
So if I understand your situation correctly, you have two webapps and
two ejb jars running in Tomcat 5.0.x and OpenEJB 0.9.2. In essence,
you have two unrelated apps; GetIMG and NPhoneCard. In the 0.9.2 you
have to smush the ejbs together into the same openejb.conf because
there is only one OpenEJB instance for all of Tomcat and webapps. But
in the 1.0 code you could actually have two separately managed OpenEJB
instances, which seems like what you were trying to do.
How would a setup like the following suit your needs?
webapps/
GetIMG/
META-INF/ejb-jar.xml
META-INF/openejb.xml
META-INF/openejb-jar.xml
META-INF/postgresql.cmp_global_database.xml
META-INF/postgresql.cmp_local_database.xml
META-INF/postgresql.cmp_or_mapping.xml
WEB-INF/web.xml
WEB-INF/lib/openejb-loader-1.0.jar
WEB-INF/classes/<all your servlet and ejb classes>
NPhoneCard
META-INF/ejb-jar.xml
META-INF/openejb.xml
META-INF/openejb-jar.xml
META-INF/postgresql.cmp_global_database.xml
META-INF/postgresql.cmp_local_database.xml
META-INF/postgresql.cmp_or_mapping.xml
WEB-INF/web.xml
WEB-INF/lib/openejb-loader-1.0.jar
WEB-INF/classes/<all your servlet and ejb classes>
The idea expressed here is that each app is an independent mix of
servlets and ejbs. Tomcat manages the serlvets and OpenEJB manages the
ejbs. You might think of each app as a "collapsed" ear; ejbs and
servlets packaged together in the same archive and run in the same
classloader. I'm not sure if we can get Castor to play nice with
having the mapping files in your webapp, but the rest is possible.
I'm working on code now to allow for this exact setup and looking for
someone to try it out. Seems you have a great use-case.
1) Is this close to what you are trying to do and 2) are you interested
in trying this out?
