Getting java2wsdl to generate enumerations
I have a few classes that are enumerations, and I'd like it if the WSDL
generator could recognize them as such. Therefore, I followed Paul's
advice on how to pattern my class appropriately (see
http://marc.theaimsgroup.com/?l=axis-user&m=110961246509001&w=2).
However, java2wsdl doesn't recognize my class as an enumeration (it
complains about the lack of default constructor). Can anybody help me
so that I can get the WSDL generator to recognize my class as an
enumeration?
