Web service in clustered environment

I have a web service running on two clusters and the loadbalancer decides where to forward the requests. Because of firewall rules the client machine can see the loadbalancer only and the two application servers can not see the loadbalancer. I have the following wsdl files on clusters:

        </port>
    </service>
</definitions>

Is it correct that the soap address and the xsd is pointing to the loadbalancer or should they use the local cluster1/cluster2 address?

UPDATE1

Unfortunately I got the following error message. This happens in clustered environment only:

Do you know what it means? I put some logs into the contract service itself and I do not see them, so there might be some problems with the request?

You said that your application servers can't access loadbalancer. Could it be that your cluster nodes are trying to reach loadbalancer for the schemalocation and fail to do that?

If that's the problem you could try to use a relative URI for your schemalocation.

Also you could try fixing the schemaLocation="schemaLocation="http:... string.

Yes it is correct. Because this abstracts the fact that you have a loadbalancer and you can actually add more and more nodes in the future without changing anything
