Good Morning Listers, 

We're building an integration between our in-house Remedy system and an 
externally hosted SAAS system. 
The integration is via Web Services.  We're new at this and its been an 
adventure.  

Right now we're looking to consume a Web Service presented by the external 
system.  
The code that calls the external Web Service is a filter that does a set field. 

I'm trying to understand if the web service call is going out of the mid-tier 
box or going out of the main application server so that I can open the correct 
holes in the firewall.  I've read lots of documentation and I've seen 
references to it both ways.  

Also, How common is it for the WSDL from the other system to need modification 
before it works with Remedy?

Thanks for your help.
