hm, in reply to myself
i think a fieldhandler will help me out... cheerz, reinhard -----Ursprüngliche Nachricht----- Von: Reinhard Weiss Gesendet: Di 10.06.2008 17:29 An: [email protected] Betreff: AW: AW: [castor-user] cannot unmarshal my marshalled xml using a mapping file hi werner, well, things are running quite well. currently i am working on the integration of a crm tool via soap based web services using spring-ws and castor as its o/x mapper. by the way, is there a way to declare a 'marshal only' class mapping as well as an 'unmarshal only' class mapping on file basis? so that my class would marshal (only) to <?xml version="1.0" encoding="UTF-8"?> <a:A xmlns:a="http://xyz.com/A";> <a:b> <a:string>one</a:string> <a:string>two</a:string> <a:string>three</a:string> </a:b> </a:A> and could be unmarshalled (only) from <?xml version="1.0" encoding="UTF-8"?> <a:A xmlns:a="http://xyz.com/A";> <!-- here is the difference --> <a:XXX> <a:string>one</a:string> <a:string>two</a:string> <a:string>three</a:string> </a:XXX> </a:A> what i want to do is to define all my mapping files (including two mappings for the same class, one for marshalling and one for unmarshalling) at once and feed spring's castormashaller with them. during marshalling, i simply want to prevent that my class - unpredictable - marshals to the wrong structure (that is the structure i expect as input for unmarshalling). unmarshalling would be safe because it always gets the correct xml. maybe that's labyrinth-thinking. but i could reuse my class even if the xml is (slighlty) different and i didn't have to manage (un-)marshallers for my class instead. cheerz, reinhard! -----Ursprüngliche Nachricht----- Von: Werner Guttmann [mailto:[EMAIL PROTECTED] Gesendet: Mo 09.06.2008 12:28 An: [email protected] Betreff: Re: AW: [castor-user] cannot unmarshal my marshalled xml using a mapping file You are welcome, Reinhard.
