Hi Maria,
I have no idea. The stacktrance initiates from MatchMaker. Maybe you can
ask on their forum.
Cheers,

Hello,
I use *"owls-uddi-matchmaker-1.3-bin"* and *"mmclient-v1.2-src" *that
contains an interface for users to interact with the OWL-S/UDDI
matchmaker.
My goal is to do some manipulations on these codes ie add some
specificities.
So, first, I have to run this code.
I followed steps of this URL :
http://www.cs.cmu.edu/~softagents/atlas/matchmaker/
<http://www.cs.cmu.edu/%7Esoftagents/atlas/matchmaker/>__
to configure *"OWL-S/UDDI Matchmaker".*
and http://www.cs.cmu.edu/~softagents/atlas/matchmaker/
<http://www.cs.cmu.edu/%7Esoftagents/atlas/matchmaker/>
to configure *"Matchmaker Client API".***
I could do the publication of a service.
But, what I couldn't do the discovery of a service!
In the code of *"Matchmaker Client"*, I have a problem in*the class
"OWLSMatchmakerClient" *and exactly in*the method*:
*public MatchmakerResultList query(CapabilitySearch capabilitySearch)*
My problem in the line: *resultElement =
uddiProxy.send(capabilitySearch, true);*
*ie*when I send the semantic search object:*"capabilitySearch" *to the
uddi using the*"uddiproxy" *object.
I think that the value of *"resultElement"* is always null.
*So, I got always this Exception:*
javax.servlet.ServletException: *Unable to query*
EDU.cmu.Atlas.matchmaker.client.servlet.UDDIMatchMakerServlet.doGet(UDDIMatchMakerServlet.java:120)
EDU.cmu.Atlas.matchmaker.client.servlet.UDDIMatchMakerServlet.doPost(UDDIMatchMakerServlet.java:125)
javax.servlet.http.HttpServlet.service(HttpServlet.java:616)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
*And in the Tomcat Server, I got this error:*
*ERROR [http-8083-Processor25] (StandardWrapperValve.java:253) -

une exception*

Please, have you any idea about my problem? I’m really blocked for
long period.
Thank you in advance.
