I have a web service that is executed from a workflow. If I test the service outside of workflow, it runs fine. However, when I try to execute within an activity, I'm getting this stack trace:

The service is actually not even getting executed, so I'm not sure what the error is beyond VCM executing it. The only other thing that I thought may be a problem is that the activity prior to this one outputs xml which is fed into this service as an input.
Thanks,
Eric
