CXF and JEE

[wernic]

My app uses CXF 2.1.1. When web.xml is declared as an J2EE app:

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
...
</webapp>

application is deployed sucessfully. When I switch to the JEE descriptor:

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
...
</webapp>

exception is thrown:

Caused by: java.lang.ClassNotFoundException: org.apache.cxf.Bus from BaseClassLoader@15ce9f{VFSClassLoaderPolicy ...}

CXF is bundled with application (I haven't try to use JBossWS and switch from Native to CXF backend).

Any thoughts? Do I need to disable JBossWS? Or maybe using JBossWS with CXF backend is the only way?
