can answer jar need include or solution?

alright problem eclipselink version.
propably using latest 1 2.6. error means in above version class xmlunmarshaller doesn't have method. java.lang.nosuchmethoderror: org.eclipse.persistence.oxm.xmlunmarshaller.setnamespaceresolver

what see site: http://grepcode.com/project/repo1.maven.org/maven2/org.eclipse.persistence/eclipselink/
version 2.42 2.5.2 has method.

so conclusion downgrade eclipselink lib version 2.5.2.

at least give shot , check results.
