Hi,

I have an application with a web service which uses a web service with server IP 172.16.219.161

That server is going to be replaced by another server, so I have changed the old IP to a new in the wsop files.

If I search for the old IP after changing the wsop (and updating context and Regenerate Project) the old address is still there in WEB-INF/src/connectivity/ws/beans/Service1.wsdl and in web.xml

Should I be worried about that, or is it just old rubbish that never clears out?

the old IP should not be in the web.xml but would appear in the other places.

Can I edit web.xml directly, or will it be overwritten?

You have a few options
1) you could edit the wsop before deploying to enter the new ip address
2) deploy the app the alter the wsop
3) Use a CAV (configurable application variable) to set the web service location
