For webservices we usually generate java beans with the maven-jaxb2-plugin and use JAXB2 marshalling in Spring. I am wondering how to handle (SOAP-)faults that are declared in the WSDL/XSD best. In the application I would like to use Java exceptions that are marshalled to the faults. Is this possible? I haven't found a way to generate ex...

I cannot quite understand what's going on most likely due to lack of fundamental knowledge with regards to the inner workings Exception Handling - or maybe I am just missing something obvious.

Why doesn't F# naturally support a try/with/finally block?
