I think you definitely need the jta-data-source. Nothing will work
without it, that's the main jdbc connection for the jpa provider.
Toplink might work without the non-jta-data-source, my only
experience is with openjpa and derby, where I couldn't get it to work
right (I think due to my lack of understanding of some derby
configuration).
The problem seems to be in the JNDI name of the data source, so
I've tried
in a separated project to establish a simple connection with the JNDI
provider of my geronimo server. My code is :
Properties properties = new Properties();
properties.put("java.naming.factory.initial",
"org.openejb.client.RemoteInitialContextFactory");
properties.put("java.naming.provider.url",
"127.0.0.1:4201");
// properties.put("java.naming.security.principal",
"myuser");
// properties.put("java.naming.security.credentials",
"mypass");
Context ic = new InitialContext(properties);
System.out.println(ic.getNameInNamespace());
//Object obj = ic.lookup("jdbc/BigDB");
There's no possible way this will ever work. Geronimo doesn't try to
export connector deployments. You can only look up datasources in
the vm they are running in.
and throws the exception :
javax.naming.AuthenticationException: Cannot open object output
stream to
server: ; nested exception is: java.net.SocketException: Software
caused connection abort: socket write
error

The JNDI provider doen't seem to be OK ....
Any help or idea will be welcome.
Thanks.
Have you tried to use ic.lookup("java:comp/env/jdbc/BigDB");?
You can try this with
InitialContext ic = new InitialContext(), from a javaee component
running in geronimo, where you've set up a resource-ref to jdbc/
BigDB.... otherwise it won't work. I don't think you'll learn much
from this.
Also, for your persistence.xml, did you specify a dependency on
that db pool that you made in Geornimo in the openejb-jar.xml?
I'm 99% sure this is the problem.
I also think that you need both jta-data-source and non-jta-data-
source.
As noted above, you definitely need jta-data-source, and you might or
might not need non-jta-data-source.
hope this helps
