Service Discovery (was Re: Cougaar Framesets)

[Noelle Givler]

Thorsten,

Immediate failure of the query indicates that either the Provider isn't 
registered correctly or the Client isn't able to access the YP where the 
Provider is registered. Could you turn on Debug logging in 
org.cougaar.servicediscovery? That would should give some insight into 
where the process is failing.

Regards,
Noelle
