    JMS Errors...

    me bob Newbie

      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
