JAXB Features?

[Jes Sie]

I'm a newbie on JAXB. Down below is the definition of JAXB given by Sun.
Questions is, using JDOM with Crimson, can't we achieve the same functionality?
What are the significant features that JAXB has?

_______________________
(JAXB)XML-to-Java Object Binding Facility
With the JAXB facility, the developer can create two-way mapping between XML documents
and Java objects. Given an XML schema, the JAXB compiler generates a set of Java class
files that contain all of the code to parse XML documents based on the schema. A
developer using the generated classes can build a Java object tree representing an XML
document, manipulate the content of the tree, and regenerate XML documents from the
tree.

Isn't JDOM just another way of representing a DOM in memory with generalized classes?
JAXB actually creates Java code specific for representing a given XML DTD. This specific code is supported by the JAXB library of functions so a JAXB object can write itself out as a document or read itself in. You can modify the class to perform various checks, etc. and build it into your application.
Another project for doing this is called CASTOR at

Ahh, now you've got my attention. I did a site visit on http://castor.exolab.org/xml-mapping.html I'm looking at some "framework" which does this reading from an XML to a Java Object elegantly.
Assumimng you're the right person, What kind of underlying XML tech is being used on Castor? DOM or SAX? Do they use the Xerces or some other parser? etc.
