This worked in GFV2:
$AS_HOME/bin/asadmin --host $AS_ADMIN_HOST --user $AS_ADMIN_USER --port $AS_ADMIN_PORT create-jms-resource --restype javax.jms.QueueConnectionFactory --description XA Queue Connection Factory --property Name=myXAQueueConnectionFactory:SupportsXA=true jms/myXAQueueConnectionFactory
But the SupportsXA=true no longer works. Maybe I can t find it in the GFV3 manuals, nor can I find it via our friend Google: how to specify XA transactionality using asadmin to configure the factory? Anybody out there know how?
