Using JAXB with the bundled JRE

I am not sure how to use JAXB with KNIME. I have no problem when I use it with for example Sun JavaSE 6u14, but when I try to unmarshall an xml, I get this error message:

Exception in thread “main” java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/C:/Users/test/progs/eclipse_knime_2.0/jre/lib/endorsed/jaxb-impl-2.1.10.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.5.0/docs/guide/standards/)

I tried to generate the classes (xjc) with -target 2.0 too, and got the same error message.
Thanks, gabor

Never mind. It looks I put jaxb-impl-2.1.10.jar in the JRE bundled with the development platform (without the API), but forgot about it. With the normal KNIME it is not included. I am sorry about the confusion.
