JAXR uses SAAJ to send soap messages to the registry. In the non-IFR case, the SAAJ impl classes are under lib/webservices-rt.jar. In the IFR case, the SAAJ classes are still under lib/webservices-rt.jar. In addition, saaj-impl.jar is located in the /usr/share/lib directory. This jar file is picked up by Enterprise Server and has precedence over classes from webservices-rt.jar. This jar file does not have the necessary security permissions to send soap messages to the Web services registry. The packaging should be modified to grant permissions to the jars under /usr/share/lib directory or not depend on the /usr/share/lib jars.
