I'm trying to get the web platform up and working so that it connects to a test data dictionary. For testing, I've enabled DbEnableQueryService, and am trying to pass a query via the query service, like so:

http://localhost:6272/adsweb/myDB/v1/__query?statement=select * from myTable

I have user authentication enabled, and am able to authenticate correctly. I know I'm talking to the database succesfully, because if my query contains an object that the user can't access, I'll get 7200 and 7087 errors back:

Cannot open table or view for this operation because the requested permissions have not been granted to the user.

If I try connection to an object that the user does have permission on, I get the following:

This page contains the following errors:

error on line 18 at column 16: error parsing attribute name

Below is a rendering of the page up to the first error:

__query http://myMachineName:6272/adsweb/myDB/v1/__query http://myMachineName:6272/adsweb/myDB/v1/__query

Any ideas on what I need to do to get this working, or where I can look for more meaningful error messages? The only thing I see in the Apache logs is in the access log, which doesn't provide any help.
