Overview
Copia collegamento

The Apache CXF WS-Addressing feature element is defined in the namespace http://cxf.apache.org/ws/addressing. It supports the two attributes described in Table 18.2, “WS-Addressing Attributes”.
Expand
Table 18.2. WS-Addressing Attributes
Attribute NameValue
allowDuplicates A boolean that determines if duplicate MessageIDs are tolerated. The default setting is true.
usingAddressingAdvisory A boolean that indicates if the presence of the UsingAddressing element in the WSDL is advisory only; that is, its absence does not prevent the encoding of WS-Addressing headers.

Configuring WS-Addressing attributes
Copia collegamento

Configure WS-Addressing attributes by adding the attribute and the value you want to set it to the WS-Addressing feature in your server or client configuration file. For example, the following configuration extract sets the allowDublicates attribute to false on the server endpoint: 
<beans ... xmlns:wsa="http://cxf.apache.org/ws/addressing" ...>
    <jaxws:endpoint ...>
        <jaxws:features>
            <wsa:addressing allowDuplicates="false"/>
        </jaxws:features>
    </jaxws:endpoint>
</beans>
