Because URL has no default public constructor. When you pass it in as a root object Castor doesn't do this check (since you can pass in an instatiated root object to the unmarshaller as well) but when the object is embedded deeper in your class hierarchy Castor is the one that needs to create the object. So if it has no default public constructor then it won't be introspected and therefor not included in your output.
There are a couple ways of dealing with this: 1. Return a string instead of a URL -or- 2. Write your own FieldHandler (extend GeneralizedFieldHandler) to convert the URL to and from a string - Requires a mapping file to be used to specify the handler. --Keith Werner Thiemann wrote: > > Hello Erik, > > I am not using a mapping-file. > > But I don't think that thats the problem. > The problem is (and thats the reason I put this on the developers mailing > list), that when I create an URL and marshal it straight I get a propper URL > representation in my XML file.
