Tried to post this via email but didn't show up, so posting via web.
Apologies if it appears twice
I'm using a webservice that requires that i first call a Login method,
extract the returned cookie and pass that in subsequent requests. The
object that brokers calls to this service is persisted in the
application scope (via coldspring) so as not to require a call to
Login for every request to the web service. However, what i'm after
is the SOAP xml returned in the response, not the java objects
returned by cfinvoke, and to get at that i need to call a method on
the cf webservice object after cfinvoke has called the method. My
assumption is that i'm going to need to single-thread access to the
webservice object within the call method, otherwise i may get the xml
from a request made in a different thread, but this is going to cause
a severe bottleneck at a very busy point.
The code snippet below should give you an idea of what i'm upto.
I wondered if anyone might have any thoughts on whether this is the
best way to handle this scenario?
Cheers, Chris
