[jboss-user] [Messaging, JMS & JBossMQ] - JMS Errors...

I'm developing a web appication using stateless sessionbeans, servlets and hopefully the timerservice and an mdb.  I have a very simple example of this however I am getting an exception in my log which I can not determine the source of.

the mdb descriptor is as follows:
<ejb-jar>
  |     <enterprise-beans>
  |         <message-driven>
  |             <ejb-name>AutoSaveMDB</ejb-name>
  |             <ejb-class>com.autosave.mb.AutoSaveMDB</ejb-class>
  |             <transaction-type>Container</transaction-type>
  |             <acknowledge-mode>AUTO_ACKNOWLEDGE</acknowledge-mode>
  |             <message-driven-destination>
  |                 <destination-type>javax.jms.Queue</destination-type>
  |             </message-driven-destination>
  |             <resource-ref>
  |                 <res-ref-name>jms/DLASCF</res-ref-name>
  |                 <res-type>javax.jms.QueueConnectionFactory</res-type>
  |                 <res-auth>Container</res-auth>
  |             </resource-ref>
  |         </message-driven>
  |     </enterprise-beans>
  |     <assembly-descriptor>
  |       <container-transaction>
  |         <method>
  |           <ejb-name>AutoSaveMDB</ejb-name>
  |           <method-name>saveDL</method-name>
  |         </method>
  |         <trans-attribute>Required</trans-attribute>
  |       </container-transaction>
  |     </assembly-descriptor>
  | </ejb-jar>

timer service descriptor:
<server>
  |   <mbean code="org.jboss.varia.scheduler.Scheduler" 
  |          name="DLAutoSave.Monitor:service=Scheduler">
  |     <attribute name="StartAtStartup">true</attribute>
  |     <attribute name="SchedulableClass">com.dlens.autosave.timer.AutoSaveTask</attribute>
  |     <attribute name="SchedulableArguments">SampleArgument,42142</attribute>
  |     <attribute name="SchedulableArgumentTypes">java.lang.String,long</attribute>
  |     <attribute name="InitialStartDate">NOW</attribute>
  |     <attribute name="SchedulePeriod">15000</attribute>
  |     <attribute name="InitialRepetitions">-1</attribute>
  |   </mbean>
  | </server>

The actual mdb and timerservice code was written by a consultant but appears to be pretty sane.. however the exceptions do not indicate (intuitively to me atleast) that it originates in our source.  This is the exception we are getting - and it occurs each time the timerservice is triggered:

I'm really kinda stumped.. any thoughts or directions I should follow?

Thanks
