the only thing i want to do is to read and write xml-files specified by a xsd-file. i tried jaxb but it ignores all restrictions in object space (no validation).
so i stumbled across emf. it seems to do - among other things Wink

- exactly what i need.
in meanwhile i generated code from the xsd i need. but what now? At the end i want a minimum set of classes and dependencies to read and write xml files respecting the underlying xsd - and use them in a maven project. how to do this?

splitting it up in subquestions:

- how to use the generated code to read/write xml files?
- how to cut or generate an artifact out of the emf-eclipse-project to be used as "myxmlapi"(.jar with needed dependencies)

thx in advance

I'm not surprised. Restrictions are just not well expressed/represented
in Java or any other object oriented language (which focus on extension).

If you invoke Generate Test Code you'll end up with a small example that
reads and writes instances.

If you run the generated XyzExample.java you'll get the idea. The XML
binding article on the documentation page is quite useful too.
