Dear Kurt,In reality, This reply not help me.
The problem comes from the class: OWLSMatchmakerClient , and from this line:
resultElement = uddiProxy.send(capabilitySearch, true);
I obtain always: resultElement[Fault: null]and in the Tomcat server, I obtain
this error:

Hi Maria,
Was Tom's reply helpful at all?
"What this error is telling you is that <capability_search/>
is not a valid UDDI element. This looks like it is some
enhancement added by OWLS or MatchMaker, but this is not in the UDDI
specification and is in no way supported by jUDDI.
http://semwebcentral.org/pipermail/owlseditor-developer/2005-February/000162.html
My advice would be to run through the OWLS/MatchMaker configuration
with a fine toothed comb, because my guess is that you have
something misconfigured or installed incorrectly. We don't
support this though at all whatsoever."
Thx,
--Kurt

Hello,
I am a master student.
I work on the discovery of semantic web services.
I want to know with
which tools you are working?
I use "OWLSMatchmakerClient
v1.2" on the client side, "juddi v0.8" and "OWLS/UDDI
Matchmaker v1.3" on the server side.I could do
the publication of a service.But, I couldn't do the discovery
of a service!
In juddi and especially in juddi.log, I get this
error when I send the semantic query:
ERROR
org.juddi.handler.HandlerMaker - can't find handler for
element type "capability_search".
The element "capability_search” is
a tag.
This message comes from this line:
public
static final String UDDI_TAG = "capability_search";
By accessing juddi.jar
In the class HandlerMaker, I
understand that this problem exists because handler =
null.
But, I am not understand the
problem!!!!
I want to know if there is a
configuration for "HandlerMaker" or “UDDI4j.jar”
Please, have you any idea about my
problem ? , I am
really blocked.
Thank you in advance.
