Christian Ewers commented on MUSE-182:
--------------------------------------
I found the problem, sorry I could see it myself. (see log-output below). The
SimpleEntry tries to remove itself from it's ServiceGroup without having one.
Simpleentry.java - line 155
ServiceGroup sg =
(ServiceGroup)getServiceGroup().getCapability(WssgConstants.SERVICE_GROUP_URI);
sg.removeEntry(getWsResource());
There should be a test, if sg is null. Perhaps as simple as this?
if(getServiceGroup()!=null){
ServiceGroup sg =
(ServiceGroup)getServiceGroup().getCapability(WssgConstants.SERVICE_GROUP_URI);
sg.removeEntry(getWsResource());
}
I think this should solve it.
But I think it would be better to test the possibility to schedule the
termination of the entry at the beginning of the createEntry-method before the
actual create-method. That would save resources and reduce message-exchanges
that are needed for the MemberShipRules-check.

> Key: MUSE-182
> URL: https://issues.apache.org/jira/browse/MUSE-182
> Project: Muse
> Issue Type: Bug
> Components: WSRF WSSG ServiceGroup
> Affects Versions: 2.1.0
> Reporter: Christian Ewers
> Assigned To: Dan Jemiolo
> Fix For: 2.2.0
>
>
> I tried to add a Resource to a ServiceGroup with an InitialTerminationTime
> by using the standard WS-ServiceGroupEntry-1_2.wsdl.
> But the Entries were never destroyed...
> I figured out that I didn't declare the wsrl-TerminationTime and
> wsrl-CurrentTime properties and I didn't declare the
> ScheduledTermination-Capability.
> The SimpleServiceGroup capability checks for the
> ScheduledTermination-Capability and only if it gets it it schedules the
> terminaton of the entry.
> When looking for the fault I found a incompatibility to the specification.
> According to the standard the add() method should fail when it can not
> schedule the termnination:
> From http://docs.oasis-open.org/wsrf/wsrf-ws_service_group-1.2-spec-os.pdf
> - line 493
> ---
> If the ServiceGroup is unable or unwilling to set the TerminationTime
> resource property of the ServiceGroupEntry resource to the given value of
> the "absolute time" form or a value greater, then the Add request MUST
> fault"
> ---
> So I think the createEntry-method of the SimpleServiceGroup should throw a
> AddRefusedFault when it can't find the "scheduled-termination"-capability.
