JCA/WSA - "unsupported resource adapter"   

Hey there,

I've been trying to write a new adapter using the Websphere Adapters Toolkit. I'm working with WID 6.2.0.1, Websphere Adapters Toolkit 6.2, on Windows XP.
So I create a new connector project, and select websphere adapters, a WPS runtime, and only "outbound processing" from the code generation list. In my module project, I right click the Assembly Diagram and click "New" and "External Service". I select "Unlisted Adapter" from the list, and then the connector project. The result is the message "Unsupported Resource Adapter".
The strange thing is that when I try to create a new External Service for the Visual Test Adapter (http://www.ibm.com/developerworks/websphere/downloads/wat/) using exactly the same process, it works fine. I have an MQ to Test Adapter flow up and running.

This might have something to do with the adapter RAR file, which I'm not sure how I'm supposed to create. For the time being, I simply click "Export" and create the RAR file under the Connector Project directory. But having or not having a RAR file doesn't seem to affect the aforementioned error message.

I haven't been able to find any information concerning this error message, or a step-by-step guide on how to create an adapter project from scratch (there are plenty of guides on how to create an adapter from an existing RAR file). Has anyone come across this problem? Any help will be greatly appreciated.

Cheers!
