Empty SOAPAction

[Philroc]

Hello,

I have written the following ws:outbound-gateway, which connects to
www.w3schools.com/webservices/tempconvert.asmx and converts Celsius degrees to Fahrenheit,
as a learning exercise:

<int:channel id="w3RequestsOutputChannel"/>
    <int-ws:outbound-gateway
        id="w3schoolsGateway"
        request-channel="w3RequestsOutputChannel"
        uri="http://www.w3schools.com/webservices/tempconvert.asmx"
    />

Here's my Main class:

public final class Main {
	
	private static String bodyTemplate0 =
					"<CelsiusToFahrenheit xmlns=\"http://tempuri.org/\">"
					+ "<Celsius>%s</Celsius>"
					+ "</CelsiusToFahrenheit>"
	
	public static void main(final String... args) {
		ClassPathXmlApplicationContext ctx = 
				new ClassPathXmlApplicationContext("classpath*:META-INF/spring/integration/spring-integration-context.xml");
	
		MessageChannel channel = ctx.getBean("w3RequestsOutputChannel", MessageChannel.class);
		
		String body = String.format(bodyTemplate0, "20");
		System.out.println(body);
		MessagingTemplate messagingTemplate  = new MessagingTemplate();
		
		MessageBuilder<String> mb = MessageBuilder.withPayload(body);
		Message<?> message = messagingTemplate.
				sendAndReceive(channel,
				mb.build()
		);
		
		System.out.println(message.getPayload());
		
	}  // end main
	
}

Unfortunately, I get an error from the w3schools server saying that the SOAPAction header cannot be read.
Using tcpdump, I have determined that the SOAPAction header is actually empty. As a result, I have added
a SOAP Header Mapper to my channel, which sets the SOAPAction, as follows:

<int:channel id="w3RequestsOutputChannel"/>
    <int-ws:outbound-gateway
        id="w3schoolsGateway"
        request-channel="w3RequestsOutputChannel"
        uri="$http://www.w3schools.com/webservices/tempconvert.asmx"
        header-mapper="soapHeaderMapper"
    />

 
 public class SoapHeaderMapper extends DefaultSoapHeaderMapper {
	
	    @Override
	    public void populateStandardHeaders(java.util.Map<java.lang.String,java.lang.Object> headers,
                org.springframework.ws.soap.SoapMessage target) {
	        target.setSoapAction("http://tempuri.org/CelsiusToFahrenheit");
	    }

}

The SOAP request now works. However, it seems silly to have to hard-code the SOAP Action. Is there a way to send a SOAP request without manually setting the SOAP Action?

Many thanks.

Hi!

How about this one:

<ws:header-enricher input-channel="literalValueInput">
	<ws:soap-action expression=""/>
</ws:header-enricher>

before WS-outbound-gateway?
Unfortunately we don't have a description of this component, but it is the same as core one: http://static.springsource.org/sprin...eader-enricher

Take care,
Artem
