WebServiceTemplate generated SOAP message has multiple namespaces causing SOAP Fault

[vandana]

I am running a sample similar to the one that ships with Spring-WS. The trouble is that spring generated response has multiple namespace declarations.

my input is

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<echo:echoRequest xmlns:echo="http://www.springframework.org/spring-ws/samples/echo" >hi</echo:echoRequest>
</soapenv:Body>
</soapenv:Envelope>

and the output is

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><ns1:echoResponse xmlns="http://www.springframework.org/spring-ws/samples/echo" xmlns="http://www.springframework.org/spring-ws/samples/echo"
xmlns:ns1="http://www.springframework.org/spring-ws/samples/echo">hi</ns1:echoResponse></soapenv:Body></soapenv:Envelope>

here in the output the namespace is declared thrice.

Is there any way to prevent this ... ???

any help would be greatly appreciated.
I face a big problem when i try to code a Spring WS client. here because of multiple namespace generation SOAPFault occurs. I used a TCP monitor to trace the generated request when using WebServiceTemplate

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><ns1:echoRequest xmlns="http://www.springframework.org/spring-ws/samples/echo" xmlns="http://www.springframework.org/spring-ws/samples/echo"
xmlns:ns1="http://www.springframework.org/spring-ws/samples/echo">hi</ns1:echoRequest></soapenv:Body></soapenv:Envelope>

The spring client code is

public class ExampleEchoTestClient {
private static final String MESSAGE ="<echoRequest xmlns=\"http://www.springframework.org/spring-ws/samples/echo\">hi</echoRequest>";


private final WebServiceTemplate webServiceTemplate = new WebServiceTemplate();

public void setDefaultUri(String defaultUri) {
webServiceTemplate.setDefaultUri(defaultUri);
}
public void callService(){
StreamSource source = new StreamSource(new StringReader(MESSAGE));
StreamResult result = new StreamResult(System.out);
webServiceTemplate.sendSourceAndReceiveToResult("h ttp://localhost:1234/ExampleEcho/services",source, result);

}
}


here due the multilple namespaces case i get this fault in my test case

org.springframework.ws.soap.client.SoapFaultClient Exception: Could not access envelope: org.xml.sax.SAXParseException: Attribute "xmlns" bound to namespace "http://www.w3.org/2000/xmlns/" was already specified for element "ns1:echoRequest".; nested exception is javax.xml.soap.SOAPException: org.xml.sax.SAXParseException: Attribute "xmlns" bound to namespace "http://www.w3.org/2000/xmlns/" was already specified for element "ns1:echoRequest".

IS THERE ANY WAY TO CONFIGURE THE NAMESPACES GENERATED BY SPRING CLASSES ?

[stirlingjava]

I experienced the same problem: duplicate xmlns declarations.

The posting http://forum.springframework.org/showthread.php?t=36432
suggests changing the XML/XSLT libs. It suggests saxon 8.7.

I placed xercesImpl-2.8.1.jar and xalan-2.7.0.jar into my classpath
(as per the samples in spring-ws-1.5.0-m1) and the problem went away.

Maybe you should try something similar?

Cheers, Ashley

Thanks a lot for the timely reply it worked ...

Hope this gets documented in the spring-ws documentation........

Any help pointers would be greatly appreciated.
Also if some one can post the link to download Spring WS example ...


TIA
