Hi!
Assuming you have the anyname.com name registered to the server address in question, you may already be ready to invoke the service as you describe.
The only thing you need to make sure is how your server handles a request for the WSDL of the service using the following URL:
http://anyname.com:9081/TradeSystem/services/FindTrade?wsdl
Some servers, namely GlassFish, will detect the server address used in the request for the WSDL and automatically insert it into the returned WSDL, replacing the address of the service.
If your server does not do this, then you may have to edit the WSDL manually and redeploy the service.
Best wishes!
