Java Mapping using JAXB

hi *, i am trying to implement a JavaMapping using JAXB.

during runtime i get a ClassNotFoundexception on javax.xml.bind.Element

i have tried adding the JAXB classes to my archive that i import - no success

i have tried referencing the JAXB classes in the MANIFEST.MF file like so:

Manifest-Version: 1.0
Class-Path: jaxb-api.jar  jaxb-impl.jar  jaxb-libs.jar  jax-qname.jar 
  namespace.jar  relaxngDatatype.jar  xsdlib.jar
Built-By: Daniel Koch

i would not like to import each JAXB archive individually.

please can someone assist me to solve my class-path problem.
