mmh... I'll probably need to try reproducing this locally.
Btw, did you try something like:
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
<deployment>
<dependencies>
<module name="com.oracle" export="true" />
<module name="com.logibec.parameters" export="true" /> <!-- parameters -->
<module name="org.apache.cxf.impl" export="true">
<imports>
<include path="META-INF"/>
<include path="META-INF/cxf"/>
</imports>
<exports>
<include path="META-INF"/>
<include path="META-INF/cxf"/>
</exports>
</module>
<module name="org.apache.cxf" export="true">
<imports>
<include path="META-INF"/>
<include path="META-INF/cxf"/>
</imports>
<exports>
<include path="META-INF"/>
<include path="META-INF/cxf"/>
</exports>
</module>
</dependencies>
</deployment>
</jboss-deployment-structure>
