Requesting working sample SOAP call for FindService and for IntegrationManagementService

Summary:

We have two scenarios we are trying to accomplish using the Taleo SOAP webservices:

1. Use the webservice to get a list of candidates/job submissions with a certain status.
   We assume the best webservice to use is:  https://host:port/smartorg/soap?ServiceName=FindService
   Specifically the findEntities method.
   However, all of our attempts to get a working request (even a simple request to get a single candidate) are failing with generic errors.
   ASK:  We would like a simple sample SOAP request (including header details, as needed) for the FindService webservice.
2. Use the webservice to submit a document to attach to the job submission .
