Is wsdl used at runtime for actually making a conn

Question

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?

Answer 1

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.
