[AG-TECH] AG 2.2 Shared Apps

[Brian Corrie]

Hello all (mostly Argonne folks),

I "think" I have written an AG 2.2 shared application. My question is 
about backwards compatibility with AG 2.1.2 venue servers etc.

I can successfully register my shared app with agpm on my 2.2 client on 
my laptop. When I connect to a 2.1.2 venue server sure enough it shows 
up in the client as a shard app. I can even add it as a shared app to a 
venue. That is where I hit a snag. Should I be able to run a 2.2 shared 
app, using a 2.2 Venue Client, but with a 2.1.2 venue server???

It appears not thus far... The first clue is that the app URL that is in 
the Properties dialog for the shared app has the form 
https://venueserver.netera.ca:8000/112. This is the 2.1.2 form I 
believe. In looking at Susanne's Shared Question Tool her test stub has 
a URL of the form 
https://venueserver.netera.ca:8000/Venues/default/apps/somebighexstring.

When I try to open the shared app in the venue client I get nothing... 
no errors, no results! When I run my shared app from the command line 
(this used to work in 2.1.2) I get a credential error as enclosed below. 
I suspect this is the same problem (although the shared app doesn't tell 
me anything when I run it from within the Venue Client). I am using the 
app URL from the properties dialog in the client.

Any thoughts?

Cheers,

Brian

p.s. Where does the log file go when you run something from within the 
venue client??? I could not find it in the Logs directory...
