After i have used wsdl to generate web service client classes, do i still need to use the wsdl at runtime? It seems like i dont have to, but in the generated classes , I see a url link to the wsdl file. So is the wsdl needed at runtime for the client to consume the web services?

It depends on the language. You didn't specify what you're using, but - for example...
- In c#, if you generate a proxy via Visual Studio, the WSDL is not used at runtime; it generates a class for you that is used instead.
- I have seen other clients that require a local copy of the WSDL; older versions of the MS Soap Toolkit required one. We ran into this when using that toolkit with VB6.
- According to this question, java requires a wsdl at runtime because some dependencies are generated at runtime.
