Value of wsa:Action in a subscribe message exchange pattern

Hi,

I've created a service that implements the operations and resource props. for NotificationProducer. In looking through the FileSystem example's soap requests, the soap Action header seems to be:
<wsa:Action mustUnderstand="1">
http://ws.apache.org/resource/example/filesystem/FileSystemPortType/yourWsdlRequestName
</wsa:Action>

However, the WS-BaseN spec. states that it should be:
<wsa:Action>
http://docs.oasis-open.org/wsn/2004/06/wsn-WS-BaseNotification-1.2-draft-01.wsdl/NotificationProducer/Subscribe
</wsa:Action>

What should the value be set to?

Thanks
Latha

Hi Latha,

You are correct. Based on the message exachange examples in the WSN 
spec, the wsa:Action should be 
"http://docs.oasis-open.org/wsn/2004/06/wsn-WS-BaseNotification-1.2-draft-01.wsdl/NotificationProducer/Subscribe". 
However, since the June 04 spec does not normatively mandate that the 
Action have that value, we do not require that it have this value. In 
fact, we currently ignore the Action and instead dispatch requests using 
the QName of the first body element. The current drafts of WSRF and WSN 
do mandate standard Actions for each of the spec operations, so once we 
upgrade to support those, we will start using the Action for 
dispatching. In the mean time, I'll update the Actions in our sample 
requests so that they are consistent with the examples provided in the 
WSRF and WSN specs.

Thanks for pointing this out!
Ian
