I created a package src.main.resources under my TestProject .Then under this package creates META-INF/services/commonj.sdo.impl.HelperProvider.The source folder for Test Project included all the packages under this project.Therefore src.main.resources is also on the classpath.But still I have NPE for XSDHelper.INSTANCE
