strangely, the Exception goes away when I specify a wire format of "jmsTextXML"
on the binding (as shown below), but not if I specify "jmsdefault". I don't
expect
to be passing text messages. Can anyone point me to a ggod explanation of wire
formats, or otherwise guess what's going on?
<service name="LogService">
<interface.java interface="com.softwareag.ps.platform.log.LogService"/>
<binding.jms
initialContextFactory="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
jndiURL="tcp://localhost:61619">
<destination create="ifnotexist" name="RequestQueue" type="queue"/>
<ts:wireFormat.jmsTextXML/>
</binding.jms>
</service>
