Problem getting RESTful web service reference working with header value

Question

Hi,
I posted this on Apex Listener forum but since I am not sure problem is with my Application RESTful web service reference or a Listener issue, I am posting here as well:
I am on Apex 4.2.2 and Listener 2.1 and the listener is on WEblogic.
I succeeded to get a RESTful web service working in an application with no header to obtain a full set of data. The data set is very large, so I am now just trying to set up a web service to get a set of data based on a student ID.
I followed the examples shown in the RESTful web service module of SQL Workshop and set up a handler of this type:
https://ourweblogicserver/apex/bnr/ace/students/course_grades/{stid}
The test for this handler succeeded both for JSON output and CSV output in the Workshop test environment.
However, when I try it from a Web Service Reference that I created for my application following what looked like the same approach used on the example video, I get NO data back. If I put a 'stid' directly into a URL of a web browser and do the basic authentication I get the data!!
This is what I have for the Web service reference:
https://ourweblogicserver/apex/bnr/ace/students/course_grades/{stid}
Basic auth set to Yes -- and this is working -- I am able to authenticate
HTTP method Get
output format Text
no response Xpath
no response namespace
defaults for new record and parameter delimiter
NO REST input parameters
Output set for all the fields in the data set queried (same set of data as in my rest service which does not have any http header)
REST HTTP Header : Name stid
I there something I am missing. I am not sure how to troubleshoot this further.
I also tried exactly following the example shown on the Oracle Video for RESTFul web services at
http://www.youtube.com/watch?v=gkCvd6P8_OU
and I can't get the 2nd example to work either-- where the header has the bind variable parameter.

Answer 1

I was able to resolve the problem -- in the latest version of the RESTful web service that I created, I had left out the creation of the Header Parameter bind variable. Once I did that everything works fine!! I was able to test in the application and got the record of an individual student.
Thanks,
