We have not been able to consume the services yet. I have generated

Finally, I could generate stubs for AG soap interfaces
(CommunityVenueServer, VenueServer, Venue and VenueClient) using
wsdl2java with files *Binding.wsdl. I used wsdl files located in CVS
repository instead of requesting wsdl from server. Now I have several
questions:<br>
<br>
- There was a file generate.py which I ran and generated extra wsdl
files: CommunityServerBinding.wsdl and CommunityServerInterface.wsdl.
What is CommunityServer service for? Searching in Google I understood
that it has security purposes but reading the generated code I cannot
deduce its function. Does this service accept requests in the same port
as VenueServer?<br>

You should be able to consume

something is wrong with our WSDL, ZSI, or your other-language SOAP

For what it's worth, I know other people have consumed the AG web

Another question: we are trying to consume Venue and VenueServer web
services without success. Now, I understand that as AccessGrid relies
on Globus Toolkit (I have heard about it before, but I understand it
better) we need to construct clients compatible with it. Using JAX-WS
(used by Netbeans IDE) is not a good idea. Am I in the right way??<br>

First of all, thanks again for your help, I have several questions,
this time related to server certificates. Do the things we were talking
about identity certificates apply to server certificates?. We have a
developer who is working in consuming AG server web services from a
Java Client. He would like to work at home, but unfortunately our
request for opening certain tcp ports was denied because of security
issues. I told him to run server and client in his machine. I had to
make a server certificate request to be able to run the server first

</span>You can build up the required certificate state
completely
independent
from the Access Grid Developers CA if you want. In that case, you'll
have to make sure that the CA cert is installed at both the server and
at client machines. And the CA cert will have to be used to sign the
certificate used to run the server. This is standard PKI practice, so
you should be able to find sufficient references online. If you have
trouble, please ask.<span><br>

Luis:<br>
<br>
There are a few things you need to know in this regard:<br>
<br>
- By default, AG3 venues do not require that clients have a certificate<br>
to enter. Venues can be optionally configured to require a certificate,<br>
in which case the user must present a certificate that satisfies the<br>
access controls on the venue.<br>
<br>
- You can run your own CA and issue your own certificates. In that<br>
case, you'll need to make sure your clients have both your CA<br>
certificate and their personal certificate.<br>
<br>
Otherwise, this is general PKI. If you have other questions, don't<br>
hesitate to ask.<br>
