I am working on a system which accepts an XML file and converts the file into local Java Bean type objects for further processing. On completion of processing the system converts the Java Beans into a response XML file and returns the file to the client. I am using Castor to perform the mapping from XML to Object and back to XML. This has been fine until now, but the messages are becoming increasingly complex which is resulting in a mapping file which is hard to read and maintain.
Can anyone please give advise on an alternative to Castor? Preferably one which has a GUI so that I don't have to code mappings by hand. The tool would have to cope with complex data structures and features such as interface/abstract reference variables.
