Tools for converting XML schema to Java objects

I have an XML schema (.xsd file) which contains a list of elements I want to convert into the correspondent Java objects. The element contains the tag which is not supported by WebLogic yet. I wonder if there are any Web service servers and/or tools for auto conversion from XML schema (with tag) to Java objects, and for auto generation of necessary serialization/deserialization java classes, handler classes and type mapping file.
