That sounds right to me. I won't guess at whether there are quirks
in Orion's JNDI implementation because I just don't have enough
experience to know if my attempts to traverse the namespace should
have succeeded or not! Kinda hard to tell from the spec, either
that or my reading of the spec has not been careful enough.
Mmmm, the only response I've ever had to a question to
[EMAIL PROTECTED] indicated that I should use
com.evermind.OrionConnectionDataSource with Oracle. The sample
they gave me was:
------------------------------------------------------
Hi, for an ordinary data-source:
<data-sources>
<data-source
name="Default data-source"
class="com.evermind.sql.ConnectionDataSource"
location="jdbc/DefaultDS"
pooled-location="jdbc/DefaultPooledDS"
xa-location="jdbc/xa/DefaultXADS"
ejb-location="jdbc/DefaultEJBDS"
url="jdbc:oracle:thin:@host:port:dbname"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="xxx"
password="yyy"
schema="database-schemas/oracle.xml"
/>
</data-sources>
Then use the ejb-location in your resource-ref, it is pooled and
transactionally secure.

---------------------------------------------------
I haven't had a chance to work with this data-source, as it took
two weeks before I finally got the random hint to use "jdbc/*"
instead of "java:comp/env/jdbc/*". Since then there's been the
minor issue of getting a revision out the door!
The strangest thing is, I have been unable to find any doc
for the OrionConnectionDataSource, and also have been unable
to find any evidence of it in any jar file! But a data-source
using it does in fact load fine.
Let me know what happens if you try it!
Good luck,
Gary
