Re: uimaFIT: external resource bindings?

[Richard Eckart de Castilho <re...@apache.org>]

You're using a ConceptMapper class which contains @ExternalResource annotations, right?
Otherwise, I'd be surprised if this worked, because otherwise there should be no 
external resource dependencies defined in the sentimentMapper description.

So you can create it manually using createDependencyAndBind(), which performs steps 2 (using the createDependency() call) and 3 (using a bindResource() call). Of course, you can also manually call createDependency() and bindResource() separately - which I think you were asking for.
