Hello,Thank you for your fast reply. So, what version of "juddi" should I use. I like to use like this architecture: http://www.cs.cmu.edu/~softagents/atlas/matchmaker/details.htm
Any idea please.

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. --Tom On 05/14/2012 04:46 PM, Maria Din wrote: Dear Kurt, In reality, This reply not help me.

"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 On 5/14/12 10:07 AM, Maria Din wrote: 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
