Re: JNDI lookup fails with Hibernate + application-scoped datasource

Hi David,
Thanks for your prompt reply.  I tried digging into what the actual  
JNDI
name was for the data source as you suggested and also went with the
standard Geronimo JNDI as well (as opposed to the EJB JNDI).  Here’s  
what I
found:

In both the Hibernate-JPA and Hibernate-Core case, the data source  
showed
(in the Geronimo console’s JNDI Viewer) as:
jca:/default/Psop_EAR50_Test/JCAManagedConnectionFactory/jdbc/psop/ 
derbyDs1

The fact that it's the same in both cases makes sense, since I'm  
declaring
the data source at the application level and it doesn't change based  
on what
EJB module I'm using.  If I look at the Database Pools view in the  
console,
I see my data source with "jdbc/psop/derbyDs1" as its name and  
deployed as
"default/Psop_EAR_50_Test/1.0/car".  Again, the same for both cases  
and as
expected.

Based on what you stated earlier, in the Hibernate-JPA case, Geronimo
doesn't use JNDI, it just uses the name to lookup the data source.   
And in
the Hibernate-Core case, Hibernate uses JNDI to do the lookup.

I guess my next question is -- is there a way to provide a "better"  
JNDI
name for a data source in Geronimo?  I'd think maybe in the  
application
metadata somwhere (application.xml, geronimo-application.xml or the
vendor-specific deployment plan for the database pool).  The reason  
I ask
is:
1)  The JNDI name is... unwieldy and non-obvious (ie. it's not  
obvious that
"jdbc/psop/derbyDs1" is registered in JNDI as "jca:/default/...." and
2)  It contains the EAR name in it, which I'd rather not have  
hardcoded into
my EJB module's metadata (for ease of portability reasons).

I am a definite opponent of using global jndi for anything partly for  
these kind or reasons.  In a  global jndi name you need a lot of  
context info to assure that there won't be naming collisions when you  
deploy 57 datasources named "myDS" for your 114 different independent  
apps.  That's why the ear name gets into the global jndi name, and why  
it will stay there.

That being said you can modify the global jndi name format with a  
template in var/config/config-substitutions.properties.  I done't  
advise it however.

I would try to declare a resource-ref in each of your ejb jars and  
look up the java:comp/env/<res-ref-name> string in hibernate.  This  
will work as long as all calls into hibernate come from javaee  
components such as ejbs (or on threads whose call stack goes through  
such a component).  This has a little more configuration but doesn't  
need the context info you are objecting to in the global name.

hope this helps

In any case, changing the data source JNDI name in Hibernate  
configuration
file gets around the publishing errors:

Hi Bevon,

I haven't looked through all the files you post but want to give a
couple hints, maybe you can easily track down what is going on.

In Geronimo, the jta-datasource and non-jta-datasource values don't
refer to anything in jndi, they basically look up components
registered in the geronimo kernel.  The JPA architecture has the
container (geronimo's jpa support) setting up an object that includes
these datasources and the rest of the info from the persistence.xml,
suitably resolved.  So, you don't need to declare any resource-refs  
in
your ejb jar anywhere to use jpa.

For non-jpa hibernate, IIUC your explanation, jndi is really used to
find the datasource(s).  I'm not clear on exactly what is getting
looked up.... I strongly advise finding out.  I also suggest using  
the
standard geronimo jndi rather than the openejb jndi context which is
unlikely to have any datasources in it since it is for looking up
ejbs.  I'd hope that if you _don't_ set the hibernate property it
would just use
new InitialContext() which ought to work.

Finally, hibernate might be trying to look up a java:comp/env jndi
name defined by a resource ref in the ejb jar or some completely
specified string for a global jndi name.  In the latter case, you'll
want to check the geronimo.log to make sure you know exactly what the
global jndi name for your datasource actually is.... it gets logged  
as
the datasource starts.

hope this helps, and if you want to update our docs when you get it
working that would be great!

thanks

First, my apologies in advance is this should be posted on a
Hibernate board.
But this seems more of a configuration issue specific to Geronimo
so...

Geronimo:  v2.1.4
Hibernate core:  v3.3.2
Derby Network Server:  v10.4.2

I was able to get Hibernate working as my JPA provider (instead of
OpenJPA)
for my EJB3 module.  However, as an academic/learning exercise, I
have been
trying to get Hibernate core working as my persistence layer for my
EJB3
module.  The problem I'm seeing is that during the Hibernate
Configuration.buildSessionFactory() call, a JNDI exception is thrown
stating
that the datasource could not be found.

I do not see this exception when I make use of Hibernate  
Annotations +
EnitityManager and stick with JPA-only API/annotations in my code.
In terms
of configuration, the EAR metadata is exactly the same (save for
swapping
the EJB3 modules).  The EJB3 module metadata has two differences:
1.  I've got a persistence.xml instead of hibernate.cfg.xml.
2.  I've added the Hibernate Annotations + EntityManager
dependencies to my
openejb-jar.xml (won't bother pasting it again here).

persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence";
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
           xsi:schemaLocation="http://java.sun.com/xml/ns/ 
persistence

My best guess -- I'm doing something wrong or it's a faulty
assumption that
my datasource will automagically be registered in JNDI (as it is
with JPA).

Please bear with me as I'm a newbie.  I've been banging on Geronimo
for just
about a month and have been at Hibernate for maybe a week.  If
someone could
shed some light on this problem or perhaps point me to some
documentation
(yes, I've read the Hibernate to Geronimo migration docs, yes, I've
googled,
yes, I did a keyword search on this forum for "Hibernate  
datasource").

Many thanks in advance!!!
Bevon
