odata services in IS 9.9

I am trying to build oData services in 9.9 for a demo. I am finding standard documentation harder to understand.

I have created my package odata services entity and relationship.

When I try to invoke it from external tool - it gives me access denied all the time. Is there a step that I am missing? Anyone has build a small tutorial on odata services that will be helpful.

You may be using a wrong parent_context. Can you attach your demo package here?

Hello Mahesh

Could you please share how to test the odata service in webMethods? It will be helpful, if you can share how to create a odata service as the standard documentation is hard to follow.
