Spring Integration Headers

[jespey]

I have a spring integration project with a ws-inbound-gateway configured with map-request-headers="*". I then use a downstream router that references header-name="SOAP-ENV:Version" . The problem I get is that that header is returned as a org.springframework.ws.soap.saaj.SaajSoapHeaderEle ment, but the header router is expecting a String.

Is there a way to execute an SpEL expression, xpath, or something else to extract the string from the element that is apparently being created?

Can you post your configuration?

    <int-ws:inbound-gateway id="ws-inbound-gateway"
                            request-channel="request" 
                            reply-channel="reply" 
                            mapped-request-headers="*"/>
	<int:header-value-router id="versionRouter" 
	                         input-channel="request"
	                         header-name="SOAP-ENV:Version"/>

Here's the log file:

Try this code and let me know

<int:router input-channel="request" expression="headers.SOAP-ENV:Version.toString()". . ./>

[jespey]

It doesn't appear to like the :

Property 'expressionString' threw exception; nested exception is org.springframework.expression.spel.SpelParseException: EL1041E:(pos 16): After parsing a valid expression, there is still more data in the expression: 'colon(:)'

[jespey]

I switched the expression to this:

headers['SOAP-ENV:Version'].toString()

And now I'm getting this:

failed to resolve channel name 'org.springframework.ws.soap.saaj.SaajSoapHeaderElement@7407beda'

. So I think we're getting somewhere, just need something besides toString()?

[jespey]

headers['SOAP-ENV:Version'].getText() worked. Thanks Oleg!

I was just gonna suggest that, but glad you found it.
