I'm working with JAXB, and I'm having trouble to unmarshall a file;

The following lines, on the beginning of the file, are causing trouble:

<!DOCTYPE package
PUBLIC "+//ISBN 0-9673008-1-9//DTD OEB 1.2 Package//EN" "http://openebook.org/dtds/oeb-1.2/oebpkg12.dtd">
<package xmlns="http://openebook.org/namespaces/oeb-package/1.0/" unique-identifier="uid">

If I delete all the !DOCTYPE it gives no Exception, but it doesn't load any value either.

The program (with the !DOCKTYPE) is throwing the exeption:

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://openebook.org/namespaces/oeb-package/1.0/", local:"package"). Expected elements are <{}dc-metadata>,<{}dc:Contributor>,<{}dc:Coverage>,<{}dc:Creator>,<{}dc:Date>,<{}dc:Description>,<{}dc:Format>,<{}dc:Identifier>,<{}dc:Language>,<{}dc:Publisher>,<{}dc:Relation>,<{}dc:Rights>,<{}dc:Source>,<{}dc:Subject>,<{}dc:Title>,<{}dc:Type>,<{}guide>,<{}item>,<{}itemref>,<{}manifest>,<{}meta>,<{}metadata>,<{}package>,<{}reference>,<{}site>,<{}spine>,<{}tour>,<{}tours>,<{}x-metadata>

Any idea how to solve this?
