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:
