Solved this issue by copying the files jaxb1-impl.jar, jaxb-impl.jar and jaxb-xjc.jar to the %jboss_home%/lib/endorsed directory. The mentioned files can be found with within the reference implementation of JAX-B (tested with versions 2.1.13 and 2.2.4) which can be downloaded from http://jaxb.java.net/.
