I have gone through your list and found out about the following facts:<br>

<div style="margin-left: 40px;">My ServiceProfileURL looks like this:<br>

Does this look right to you?<br>

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?<br>

It puts null to the new YPInfo, where there should be inserted a
YPCommunity, so I guess this is inserted at another point in the code,
but where. The SimpleSDReg..Plugin prints out <br>

In the SimpleSDR..Plugin the code for the community doesn't set the

it instead runs the else branch (yellow part) of the code and issues:<br>

To sum up, the community does not get found, the registration is
therefore not completed.<br>

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.<br>

<div style="margin-left: 40px;">About the MilitaryServiceScheme, this
is what bothered me most as well, because I thought, when using the
pizza example as my foundation, I would automatically use the
COMMERCIAL_SERVICE_SCHEME, when I look into the servlet, I also see,
that the MMQuery refers to the MilitaryServiceScheme. What can I do
about it? I have not overwritten the getServiceScheme. However I have
copied the MatchMakerPlugin to my Plugins for debugging reasons, but it
still has:<br>
<br>
protected String getServiceSchemeForRoles() {<br>
return Constants.UDDIConstants.COMMERCIAL_SERVICE_SCHEME;<br>
}<br>
<br>
in it.<br>
<br>
</div>

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(). <br>
