It's fine so long as that's the correct path to your service profiles. 
Are you writing your own method to generate it or using the method 
provided by org.cougaar.servicediscovery.Constants?

Short answer - SimpleSDRegistrationPlugin calls  findYPCommunity() to 
find the YP community for the specified agent. (That's the point of the 
initial null value in the ypInfo structure.) So it looks like there's 
something wrong in the way you've set up the community support via 
Communities.xml. The CommunityViewerServlet should show you the yp 
communities in the running society so you can see how the Cougaar is 
interpreting your Communities.xml Section 3.2.10 of the Cougaar 
Developer's Guide also addresses Cougaar community support.

Looks fine to me.

Is it possible that your plugin somehow extends 
org.cougaar.servicediscovery.plugin.MatchmakerStubPlugin instead of 
SimpleMatchmakerPlugin? MatchmakerStubPlugin does reference the 
MilitaryServiceScheme when generating ServiceClassifications based on 
MMQueryRequests - see MatchmakerStubPlugin.addRQ().
