problem overriding saaj api

[gad...@gmail.com]

I'm trying to deploy a WAR with SAAJ 1.3 (saaj-api.jar and saaj-impl.jar from JAX-WS 2.0) in WEB-INF/lib. I'm getting the following exception when trying to run my JAX-WS 2.0 web services:

I've tried setting the Enterprise Application -> [Application Name] -> Class loader -> Class loader order -> Classes loaded with application class loader first setting in the Administrative console, but it makes no difference. Apparently it's not possible to override the jaxa.xml.soap package in ${Websphere_HOME}/lib/j2ee.jar using this method. Is there some endorsed directory where I can drop these jars and override the Websphere internal SAAJ implementation?

I found another post on this forum and figured out that I was setting the Enterprise Application classloader options, not the WAR module classloader options. Now I'm getting the following exception in logs/ffdc on startup:

Exception = java.lang.ClassCastException
Source = com.ibm.ws.webcontainer.webapp.WebAppServletManager.loadServlet
probeid = 213
Stack Dump = java.lang.ClassCastException: com.sun.xml.ws.transport.http.servlet.WSServlet incompatible with javax.servlet.Servlet

I'm looking at the javax.servlet.http.HttpServlet provided in j2ee.jar with WAS 6.1 and the incompatibility is not obvious to me. Here's the source of
com.sun.xml.ws.transport.http.servlet.WSServlet:
