Java web services client

I want to build a web services client that takes wsdl link as the input and generates java classes. I know we can do this directly using Netbeans IDE where we provide the wsdl location during project setup. But I want the wsdl 开发者_如何学编程location to be provided when the client starts running. How do I do this?

Is the location that will be provided just used to specify the SOAP endpoint (for a web service whose WSDL was known at development time), or will it be a completely arbitrary WSDL?

In the first case, the web service client that was created by Netbeans has methods that accept an alternate SOAP endpoint URL. You can call those to use the client with a server whose location is not hard-coded in the client.

If however, the WSDL describes a completely unrelated service, how are you going to write Java code against it? You cannot use any interfaces derived from the WSDL (because they are not known at development time). You could only have a very generic SOAP client, where the user almost directly types in the XML that will be sent.
