Well, we have not changed the SOAP portion of our code in a very, very  
long time... And, this has worked up until very recently. I'd like to  
know if there was a change in the Java client requests. Did you change  
SOAP libraries?

It is clear there is an interoperability issue here - but it is not  
something that is easy for us to fix for already deployed services. It  
is of course something we can address in our next release. But - we  
need to come up with a way to move to that without disabling existing  
deployments if we can.

Perhaps one of you could look at a previous version of pS-UI and look  
at what it was sending before. We actually ran into this problem as  
well when attempting to demonstrate pS-UI with some of our services  
yesterday and realized this was a problem. pS-UI had always been able  
to access the Internet2 network SNMP-MA before, but that was no longer  
the case.

Also, I believe this was working just last month when Szymon was  
testing the Java hLS with our gLS implementation. So, I suspect  
something changed in your client libraries since then.

Jason, Aaron and I are in Austin at the SC08 conference, so you will  
not hear from us much (if at all) this week. (And, we are all on  
vacation with the U.S. Thanksgiving holiday next week.)

We can (and will) put something into our next release - likely in  
December. But, we have several deployments of the existing software  
(not run by us) and it will take a fair amount of time to convince  
other groups to upgrade.

thanks,
jeff
