In the response we recieve from our web service, the declaration of the namespace (xmlns:ns1="http://our.website/services/types") is repeated in every element even though only one declaration would do in the top element (ns1:myMethodResponse). Is there a way we can tell JBoss not to generate a namespace declaration if the parent element already belongs to the same namespace ? We use JBoss 4.0.4.GA Below is the response : <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> <env:Header/> <env:Body> <ns1:myMethodResponse xmlns:ns1="http://our.website/services/types" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <ns1:header> <ns1:version xmlns:ns1="http://our.website/services/types">1.0</ns1:version> <ns1:senderTime xmlns:ns1="http://our.website/services/types">2006-07-17T13:06:48.867Z</ns1:senderTime> <ns1:senderId xmlns:ns1="http://our.website/services/types">CommonBank</ns1:senderId> <ns1:language xmlns:ns1="http://our.website/services/types">NL</ns1:language> <ns1:systemSoftwareVersion xmlns:ns1="http://our.website/services/types">4.00.00.0033</ns1:systemSoftwareVersion> </ns1:header> <ns1:myMethodResponse xsi:type="ns1:myMethodResponseV1DTO"> <ns1:checkedAccountNumbers xmlns:ns1="http://our.website/services/types"> <ns1:checkedAccountNumber xmlns:ns1="http://our.website/services/types"> <ns1:accountNumber xmlns:ns1="http://our.website/services/types">BE06792503601622</ns1:accountNumber> <ns1:timestampLastAvailableDocument xmlns:ns1="http://our.website/services/types">2006-05-05T00:00:00.000Z</ns1:timestampLastAvailableDocument> </ns1:checkedAccountNumber> ... </ns1:checkedAccountNumbers> </ns1:myMethodResponse> </ns1:myMethodResponse> </env:Body> </env:Envelope> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958460#...
