take a look at the castor tests located at castor\src\tests\MasterTestSuite\xml\mapping\
Just remember (this is the most common mistake) you can not use the static methods of the marshaller if you are planning on assigning any mappings etc... http://castor.exolab.org/xml-mapping.html has all the info you need -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 22, 2003 3:10 PM To: [EMAIL PROTECTED] Subject: RE: serializer.serialize() and org.xml.sax.Attributes Thanks for the envite Dims. If I can figure out how to write a JiBXSerializer, JiBXSerializerFactory, JiBXDeserializer, and JiBXDeserializerFactory, then I will certainly do that. The Castor ones look to be pretty straight forward and don't seem to ask for any SOAP message context data. However, I'd have to play with this a bit, I don't see how one could define the Castor mapping with an XML file. Steve Maring
