Thinking; the getFeatureInfo is supposed to be in reference to a
GetMapRequest which you provide (that is you are performing your query
against a map...). I suspect that you can only perform a query against a
layer that is actually listed in your GetMap request?
Would that be the case...
You may need to check the test cases to find an example of GetFeatureInfo.

Simplify data backup and recovery for your virtual environment with vRanger.
Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
Nope - It's vRanger. Get your free trial download today.
