David,
I’m glad you like the tooling so far. Right now, we do not have any fine grained methods which work on existing WS classes or an existing WSDL file.
If you developed your webservice “Bottom Up”, i.e. code first, you do need to add more operations manually. XFire will generate an appropriate WSDL file for you.
If you developed “Top Down”, using a WSDL file, then you will need to regenerate your webservice when you upgrade the WSDL file. Note that the existing files are completely regenerated (you will be asked/warned).
Our WS tooling is constantly being upgraded and we appreciate your input.
Hope this helps,
