Since you have an earlier version of the examples, in your *-ds.xml file you
are probably listening the amq.direct exchange for the MDB queue example. This
is an exchange in AMQP and not a destination and as a result, any listener on
that exchange (by default all the MDB's) will receive the message. This has
been corrected in later versions. Note, this was really a probably with the
examples rather than with the adapter. To fix the problem in your version, in
your *-ds.xml file you can set up the HelloQueue with something like:
<mbean code="org.jboss.resource.deployment.AdminObject"
name="qpid.jca:name=HelloQueue">
<attribute name="JNDIName">HelloQueue</attribute>
<depends
optional-attribute-name="RARName">jboss.jca:service=RARDeployment,name='qpid-ra-0.10.rar'</depends>
<attribute name="Type">javax.jms.Destination</attribute>
<attribute name="Properties">
destinationType=QUEUE
destinationAddress=direct://amq.direct//hello.Queue
</attribute>
</mbean>
Also, in deploying the examples, you most likely created a queue called
amq.direct. You will want to remove this from your broker as it will cause
issues.

See above.

Good question. The max-pool-size setting is for outbound connections and
controls the number of pooled JCA connections for producing messages. You can
take a look at the file:
JBOSS_ROOT/docs/schema/jboss_ds_5.0.xsd
for a full listing of all the options supported. The JBoss JCA wiki on
jboss.org is also a good location for general JCA information
