Have a look at http://www.castor.org/xml-mapping.html#3.-The-Mapping-File in general, and the section that describes the <class> mapping in particular. E.g. the <class> element has an optional extends attribute that allows you to specify parent child relationships, etc, Regards Werner > > Regards, > -Praveen > > */Werner Guttmann <[EMAIL PROTECTED]>/* wrote: > > Please see inline .... > > Amit M Bhosle wrote: > > Hi: > > > > i'm a newbie to castor, and couldn't get things to work for the > > following use case.. would be grateful if some one could help me with > > this.. > > > > here's a simplified version of my use case.. > > i have 2 classes (say, A1, A2), which have a common abstract base > class, > > B.. > > > > my producer class generates some instances of the subclasses, and > > calls a method with the signature > > > > void consume(B b); > > > > on the consumer.. the consume method, on the other hand, looks at the > > runtime class of the argument, and delegates to a specific method.. > > > > void consume(B b){ > > if(b.getClass() == A1.class){ > > consumeA1((A1)b); > > } > > else{ > > consumeA2((A2)b); > > } > > } > > > > the producer and consumer are sitting in different JVMs, and the data > > objects are marshalled (by my communication framework) on the client > > side, transferred over the wire, unmarshalled on server side, and > > passed as the argument to the Consumer.consume method.. > > > > 1. can castor help me with this marshalling/unmarshalling without > > having to use a mapping-file. > Before trying to answer this, I'd like to understand as to why you do > *not* want to use a mapping file.
