Are you running Felix in embedded mode in JBoss? If yes then you would have to either add 'org.jnp.interfaces' to [1] - system packages extra via org.osgi.framework.system.packages.extra - OR to the bootdelegation list via org.osgi.framework.bootdelegation
This would enabled the relevant packages to be exported from base JBoss system [1] http://felix.apache.org/site/apache-felix-framework-configuration-properties.html Chetan Mehrotra
