Thanks for the link Brian. After reading the wiki page you pointed out, I determined that the problem was stemming from the way we were telling Spring about JMS. We were telling Spring to lookup the JMS Connection Factory under the JNDI name "ConnectionFactory". I switched this JNDI name to "java:JmsXA" and the problem is resolved.
