Stuck with an error while implementing Spring Integration using HTTP-outbound gateway

[AvinashMunaga]

Hi All,

I am developing a web application which calls a web-service that provides HttpBinding to implement it. So, I thought of using <http:outboundgateway> in my config file.

But, when I call the service I am getting this error -
"Caused by: org.springframework.web.client.HttpClientErrorExce ption: 415 Cannot process the message because the content type 'text/plain;charset=UTF-8' was not the expected type 'text/xml; charset=utf-8'."

This is my config file.

<?xml version="1.0" encoding="UTF-8"?>

<beans:beans xmlns="http://www.springframework.org/schema/integration"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<int-http:outbound-gateway id="example" request-channel="input_userdetails"
				url="http://xxxxxxxx/AuthenticationService/Service1.svc?wsdl"

				charset="UTF-8" reply-channel="output_sessiontoken"/>

	<!-- The response from the service is logged to the console. -->
	<stream:stdout-channel-adapter id="output_sessiontoken" />
	
</beans:beans>

Also, this is my class calling the service.

public class UserSessionID_RiskMaster {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context = 
                                    new ClassPathXmlApplicationContext("blog/authenticate-config.xml");
		ChannelResolver channelResolver = new BeanFactoryChannelResolver(context);

		// Compose the XML message according to the server's schema

		String requestXml = "<GetUserSessionID>" +
				"   <struserInfo>" +
				"      <Message><Call><Function>LoginAdaptor.Authorization</Function>" +
				"         </Call><Document><Authorization><UserInfo><UserName>csc</UserName>" +
				"	  <DSNName>RMXR7_MOBILE_FEB16</DSNName</UserInfo></Authorization>" +
				"      </Document></Message>" +
				"   </struserInfo> " +
				"</GetUserSessionID>";
		// Create the Message object
		Message<String> message = MessageBuilder.withPayload(requestXml).build();

		// Send the Message to the handler's input channel
		MessageChannel channel = channelResolver
				.resolveChannelName("input_userdetails");
		System.out.println("Headers : " + message.getHeaders());
		channel.send(message);

	}
}

The error here is that, what ever the input I am giving to the URL is going in a text/plain format. But, the service is expecting a text/xml format. So, can any one provide me information of where to change/append in my code so, that the xml I am sending to the service will be an XML instead of plain text.

Awaiting for some help as it is really necessary.

Thanks in Advance.

When creating the Spring Integration Message, set the "content-type" header to "text/xml".

HTH,

[oleg.zhurakousky]

You can set 'Content-Type' as Message header

Message<String> message = MessageBuilder.withPayload(requestXml).setHeader("Content-Type", "text/xml").build();

Since 'Content-Type' is a standard HTTP header it will be copied from SI Headers to HTTP headers.

Thanks for your reply. This error is resolved.

Now, after changing my xml as

<?xml version="1.0" encoding="UTF-8"?>

I am getting output same as my input.

Can any one help me with this as I am not able to figure out the cause of this.

Hello.

Why don't you use

<ws:outbound-gateway/>

?
And why do you make request to WSDL-URL:

url="http://xxxxxxxx/AuthenticationService/Service1.svc?wsdl"

?

Artem Bilan

Got my problem solved. Sorry for not updating. Used <ws:outbound-gateway/> and I got the response from the web service. And about WSDL, I have to use this URL to fetch information from the web service.

Thanks for the response.

[vibin12]

The below is my code , i am getting an exception. Is the WSDL referance to the url attribute is correct , if not how do i find right uri value from wsdl file, please help ..

<int:chain input-channel="httpOutboundSenderChannel" output-channel="fnoResponseChannel" >
<int:header-enricher>
<int:header name="SoapAction" value="urn:createEntitlement"/>
</int:header-enricher>
<int-ws:outbound-gateway uri="http://abcccer04:8080/abcService/services/someservice?wsdl" />
</int:chain>

[Cleric]

if not how do i find right uri value from wsdl file

Service ULR should be in the end of WDL:

<wsdl:service name="SomeService">
   <wsdl:port name="SomeService-ServiceHttpPort" binding="tns:SomeService-ServiceHttpBinding">
      <wsdlsoap:address location="http://host:port/Service-URL"/>
   </wsdl:port>
</wsdl:service>

[vibin12]

Thanks for the responce. I am having trouble use operation in the WSDL file. My wsdl contains multiple operations . i only need to invoke one operation, kindly explain how do i do that

WS input channel name: httpOutboundSenderChannel , this channel carries the XML payload- for the webservice call.

WS output channel name: fnoResponseChannel , this channel i use to receive webservice responce after invoking the WS.


I only need to invoke one operation since WSDL contains mutiple operations. Please help..

Thanks
Vibin

H-m...

Vibin, maybe you should study what is SOAP at first?
And then please read this: http://static.springsource.org/sprin...tml/index.html.
Right now it seems like you have some gaps in the theory...
And also Soap-UI is for you to help.

Take care,
Artem
