> I refer to the XSD in the jaxrs:schemaLocations section of my application context and I configure the WadlGenerator in the jaxrs:providers section as follows:
> <jaxrs:providers>
>   <bean class="org.apache.cxf.jaxrs.model.wadl.WadlGenerator">
>     <property name="applicationTitle" value="FooService"/>
>     <property name="singleResourceMultipleMethods" value="false"/>
>     <property name="addResourceAndMethodIds" value="true"/>
>   </bean>
> </jaxrs:providers>
