Hello,
already explained in the issue comment.. see
https://jaxb.dev.java.net/issues/show_bug.cgi?id=721.
there is a simple reason and a simple way how to get this working:
reason: you are using jaxb-api v2.1 from jdk 1.6
needed action: copy jaxb-api.jar (v2.2!) to jdk's endorsed dir
regards,
Pavel
