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?
Here's the log file:Code:<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"/>

org.springframework.integration.MessagingException: unsupported return type for router [class org.springframework.ws.soap.saaj.SaajSoapHeaderElement]
Try this code and let me know
Code:<int:router input-channel="request" expression="headers.SOAP-ENV:Version.toString()". . ./>
It doesn't appear to like the :
Code: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(:)'
I switched the expression to this:And now I'm getting this:Code:headers['SOAP-ENV:Version'].toString()
. So I think we're getting somewhere, just need something besides toString()?Code:failed to resolve channel name 'org.springframework.ws.soap.saaj.SaajSoapHeaderElement@7407beda'
headers['SOAP-ENV:Version'].getText() worked. Thanks Oleg!
I was just gonna suggest that, but glad you found it.
