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
