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:
