WS-Eventing and subscription expiration time

[palin]

We implemented a ws-eventing application that receives subscription messages to our service from our customers; we found that the max expiration time accepted by jbossws is 10 minutes (MAX_LEASE_TIME) after the current date; moreover subscriptions with indefinite lifetime (ie. without wse:Expires tag) are not supported. We know that ws-eventing specification states that the event source defines the actual expiration and is not constrained to use a time less or greater than the requested expiration, however we think that you should not throw an InvalidExpirationTimeException when an expiration time beyond 10 minutes from now is requested. Is there a reason I don't know for chosing 10 minutes for that constant? What about the opportunity of using your MAX_LEASE_TIME value whenever an expiration time too much in the future is received? It would be a great help for us to have MAX_LEASE_TIME and DEFAULT_LEASE provided as config parameters by the user. This would prevent a lot network traffic since less renew messages (and responses) would be sent.
Thank you

Hi, I'm a collegue of Alessio(palin).
We took a look to the code and it seam pretty easy to patch to have configurable timeout for ws-eventing.
Before go on, we would like to know some other opinions and/or the motivation of the 10 minutes choice.
Are there any other people implementing ws-eventing?
Any opinions about this problem?

Well, the idea was that event sinks periodically call 'Renew'. But i'd happily accept that patch in order to make it configreable. Could you create a JIRA for that and attach the diff to it?

Just come back from a little vacation :). I'll do that asap.
Probably I'll post some consideration about on the designer forum soon.

I checked that this was added in 1.0.4 and then removed later..
I am using WS 2.0.3. How do I configure the lease time...

The MAX_LEASE_TIME for subscription..... is it configurable?
if not then is there any patch available for that?
