Hi, Chris, James!
I have put some time into this issue and already have commented on
it in
JIRA. I think I have found the problem and already have hacked up a
solution
which I would like to elaborate on. However, James, in JIRA the
issue is not
assigned to anyone and I would like to discuss some class design
changes
before implementing a fix and submitting a patch. Who is taking care
of the
RA code? Is this you, James? Should I discuss this issue with you
directly?
Regards,
Kai

Thanks for your help with this, I'm extremely happy at how quickly
both
the ActiveMQ and Glassfish teams respond to their users and how
helpful
the response is. It's quite a change from some other projects I've
dealt
with.
Please let me know if you need any additional information from me
to help
you resolve this issue.
Thanks!

Thanks for the great feedback - could you raise a JIRA so we don't
forget this. Looks like we need to look at the serialization of the
RA's ActiveMQConnectionFactory to ensure it works nicely with being
serialized/deserialized in GlassFish

Thank you again for your quick response. I posted a forum message
describing
this issue and received a response from the Glassfish people.
This is
what
they said:
"Thanks for trying out GlassFish. Since I have only the trace
snippet
above,
I tried to debug this problem by going through ActiveMQ RA's source
available at
https://svn.apache.org/repos/asf/incubator/activemq/trunk/activemq-ra/src/main/java/org/apache/activemq/ra/
This is what I understand happens. Please correct me if there are
errors.
When ActiveMQConnectionFactory
[https://svn.apache.org/repos/asf/incubator/activemq/trunk/activemq-ra/src/main/java/org/apache/activemq/ra/ActiveMQConnectionFactory.java
]
is created at the createConnectionFactory method of
https://svn.apache.org/repos/asf/incubator/activemq/trunk/activemq-ra/src/main/java/org/apache/activemq/ra/ActiveMQManagedConnectionFactory.java
,
the ConnectionManager is initialized to a *transient* variable
"manager".
Since ConnectionFactory instances can be serialized/deserialized
while
publishing to JNDI (as is the case in Project GlassFish), the
connectionManager reference is lost and hence the NPE. The fix
ideally
should be in the ActiveMQRA's code. You could copy me [sivakumart
AT sun
DOT
com] while you are discussing this with ActiveMQ, if you wish. If
you
still
have any issues, please provide a copy of your domain.xml
[connector
connection pool, resource configuratin information] and the
entire trace
in
server.log."
Now, I'm new to all this resource adapter stuff, does that make
sense to
you?
Thanks,
--Chris

I'd suggest raising a bug against GlassFish as its sounding like
its
JCA container is not providing a ConnectionManager. FWIW the
Resource
Adapter works fine in the Geronimo JCA container so I suspect it
to be
a GlassFish bug.

Thanks for your quick response. I took a look at the change
you made
and
it
does make it clearer where the error is. However, is there any
chance
that
you might have a pointer towards how I can resolve the issue on
the
Glassfish end of things? I am using UseInboundSessoinEnabled
to work
around
the issue at the moment, but for the sake of completeness, I'd
like
to
understand how to make the container do the right thing. I've
looked
through the documentation on the Glassfish site and I've Googled
using
all
the keywords I can think of and nothing is coming up.
Thanks again,

It looks like this exception...
Caused by: java.lang.NullPointerException
at
org
.apache
.activemq
.ra
.ActiveMQConnectionFactory
.createConnection(ActiveMQConnectionFactory.java:88)
is caused by Glassfish calling
ManagedConnectionFactory.createConnectionFactory(ConnectionManager
manager)
by passing in a null ConnectionManager.
So it sounds like Glassfish is not creating a connection
manager to
use. This is only required if UseInboundSessionEnabled is not
set.
I've just updated SVN HEAD of ActiveMQ to throw a more
descriptive
error message if the JCA container does not configure a
ConnectionManager.
