I have missed one line in the second solution. Here again:
final ClassLoader cl = Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
jaxbContext =
JAXBContext.newInstance("mil.army.security.ts3.jaxb.personnel");
} finally {
Thread.currentThread().setContextClassLoader(cl);
}
Regards
Krzysztof
