Hi,
I'm getting a NullPointerException
java.lang.NullPointerException

itializeCompleted(JmsProducerCapabilityImpl.java:80)
This happens each time when I start Tomcat again and an available
subscription will be loaded.
The cycle I do is:
Delete all subscription on the file system, start Tomcat. Make a
subscribe call, get my notify message. Then I restart Tomcat. To get
Muse initialize I call GetCurrentMessage, where I get this
NullPointerException. When I delete the subscription-1.xml file, then I
can restart Tomcat, make a GetCurrentMessage call and there is no
NullPointerException.
I defined the NotificationProducer like this:
<capability>
<capability-uri>http://docs.oasis-open.org/wsn/bw-2/NotificationProducer
</capability-uri>
<java-capability-class>
org.apache.muse.ws.notification.impl.SimpleNotificationProducer
</java-capability-class>
<persistence>
<!-- saves the actual subscription data, not
just the EPR -->
<java-persistence-class>
org.apache.muse.ws.notification.impl.NotificationProducerFilePersistence
</java-persistence-class>
<!-- the location can be any directory name -->
<persistence-location>subscriptions</persistence-location>
</persistence>
</capability>
Is this a valid way, or what should be the exact way of defining a
persistence for the subscription?
Mit freundlichen Gruessen / With kind regards
