[Jamvm-general] JamVM and JAXB

[Teresa L. J. <gam...@gm...>]

Hi All,

I'm trying to compile an XML schema using JAXB 2.1.10 against JamVM:

jamvm -verbose -Djava.endorsed.dirs=/usr/local/jamvm/jre/lib/endorsed -jar
jaxb-xjc.jar messages.xsd

But I'm getting java.lang.NullPointerException. Below is a snippet from a
verbose debug stack trace:

It looks like the Gnu class (gnu.xml.validation.xmlschema.XMLSchemaBuilder)
is incompatible with JAXB's
class (org.relaxng.datatype.helpers.DatatypeLibraryLoader).

Is this an incompatibility issue?

Is JamVM/Classpath compatible with Sun's JAXB?

Any help would be greatly appreciated.
