How to get Public domain / Webserver URL on WSDL

Hi All,

I am trying to deploy a webservice on clustered weblogic server setup. The problem is whenever I install the webservice, the WSDL takes the ip address of that particular node.
Due to this every node has a WSDL with each having different ip which fails the purpose of my clustering.
What I would like to have is that I can configure the WSDL url as the webserver url which does the work of balancing the load.
Do I need to hard code each WSDL on every node in the weblogic console? I tried doing that but I could not find a place to edit as the WSDL was not published.
What could be the other options?
I am not very good at WSDL.But this problem came up when my application could not find the WSDL as we had stopped on node.Ideally it should have picked up the oher node's WSDL.

Any help will be appreciated.
Need to find a way to change the url at runtime.
