JBossWS-Native does not support WS-Security Policy, so you're right, you need to use JBossWS-Metro in your case. This said, considering the error you get, your current installation is broken, as the Metro stack seems to be looking for Native classes (org.jboss.ws.core.jaxws.spi.ProviderImpl). I'd suggest reinstalling jbossws-metro (and double-checking the result because of this issue with JBoss 4.2.3 only https://jira.jboss.org/jira/browse/JBWS-2377).
