How to handle frequently changing wsdl

We have a wsdl which is changing frequently. If I make a wsdl to java and use the xml binding using castors, it is going waste after sometime as the wsdl is getting changed. What is the solution to such a situation.

I think is a problem with SOAP. Once the wsdl changes, there is no option for the client but to update the client proxy stubs for the same.

For this very reason, we have moved to RestFull Services.

You can also try the following approaches
1) serialize the object to a xml string and change method signature to have the string as the signature.
You can do this by having the wrapper layer on top of SOAP services.
2) Try with Json format also
To handle this type of situation i have always talked to my design team to prepare the skeleton(public properties and methods) of the classes first which are going to be used. this ensures that if the web service changes it will not affect much on the client(consumer of the service may be very few changes). But this is too ideal.
