Hello, is it possible to customize the JAXB mapping Jboss uses when deserializing an incoming SOAP message for a web service or serializing an outgoing message? My problem is that I want to send and receive maps containing lists over a web service (implemented as EJB stateless session bean annotated as @WebService) in JBoss. JBoss uses jax-ws for web services and jax-ws uses jaxb for mapping Java classes to XML structures. Jaxb is not able to handle maps containing lists, so I have to define a custom mapping providing custom serializers / deserializers. I found out that there is the possibility in jaxb to write a configuration file for custom mappings that can look like this: <bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"> | <globalBindings> | <javaType name="my.package.MyClas" xmlType="xs:someName" | parseMethod="my.package.MyParser.parse" | printMethod="my.package.MyParser.print" | /> | </globalBindings> | </bindings> Ist there a possibility to provide such a file to JBoss so that it will be used when (de-)serializing SOAP messages for or from my web services?
