I'm developing a building block to connect to an external video server via the Video companies API.
I'm developing a course tool, but whenever I try to use that API I get the totally unhelpful "The specified resource was not found, or you do not have permission to access it" error.

I'm guessing I have one the following problems.

a/ Eclipse hasn't packaged the video companies jar file correctly in the war file
b/ I'm getting an error when connecting to the jar file
c/ I've not got the permissions set correctly in the manifest.
d/ other

I've checked the bb-services-log file, but there is no helpful information in there.

 the error message is next to useless can anyone give any advice on 
where I should be looking to resolve this. Log file or other place.
