> I've been trying to work through an issue with a NullPointerException run using the JCA
1.5 resource adapter on Glassfish.  In the course of debugging, Siva from the Glassfish team
provided this information:
> "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."
