You probably misundertood by the following webservice deployer output:

As you see the HelloServletImpl.class (configured in web.xml  <servlet-class>servlet.hello.helloservlet.HelloServletImpl</servlet-class>) is not a real servlet class, the webservie deployer will modify the web.xml and start the endpoint impl before the real servlet - org.jboss.wsf.stack.cxf.CXFServletExt which servers the servlt transport initialize and start to work.  These webservice deployers which output above message are executed before the web deployer to create WebContext . That's why you see it is executed after the HelloServlet is Initialized. But ServletContextListener is actually executed as expected before the real servlets are initialized. Here in your war file is after  CXFServletExt and Startup are initialized.

It is not ignored. The <load-on-startup> configured to HelloServlet is passed to org.jboss.wsf.stack.cxf.CXFServletExt.  I tried with your example it works properly.

I did not get what you want to initialize from the source code(maybe I missed something), so I am not sure if do the initialize work in a real servlet and inject something with WebServiceContext can help. Here is some documentation about how to access MessageContext and/or Http request and response: http://cxf.apache.org/docs/servlet-transport.html http://cxf.apache.org/docs/servlet-transport.html
