Maria,
Basically jUDDI is an implementation of the UDDI specification, the
version that you are using is an implementation of the UDDI v2
specification :
http://uddi.org/pubs/ProgrammersAPI-V2.04-Published-20020719.htm
"capability_search" isn't part of that.
You're using OWL-S Matchmaker, which I don't know too much about, but it
looks like something built as an extension on top of jUDDI.
"capability_search" is part of that.
Matchmaker seems to have a site here :
http://projects.semwebcentral.org/projects/owl-s-uddi-mm/
With forums here :
http://projects.semwebcentral.org/forum/?group_id=35
I'd post there, and maybe if you can find some of the authors of
MatchMaker in the code, I'd contact them.

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.

*Best regards,*
*Maria*
