Hi All,
I have simple message flow like SOAPInput ->compute node ->SOAPRequest node->SOAP reply node.
I am trying to hit the 3rd party URL in SOAP request node. Flow is routed to failure terminal of SOAP request node saying below error message.
| Code: |
RecoverableException
File:CHARACTER:F:\build\S700_P\src\WebServices\WSLibrary\ImbWSRFC822HeaderParser.cpp
Line:INTEGER:678
Function:CHARACTER:ImbRFC822HeaderParser::checkReservedHeaderNameUsage

Text:CHARACTER:Content-Type

Text:CHARACTER:HTTP |
When i googled i understood that above error is WMB bug and it is fixed in APAR IC99401 and this fix is avilable in WMB 7.0.0.8 as per the https://www-304.ibm.com/support/docview.wss?uid=swg24041187.
I am using WMB 7.0.0.8 broker and executed below command.
| Code: |
| mqsichangebroker LOCALBRK -f 7.0.0.8 |
After running the above command also i am facing same issue.
Can you please show some light on this issue. Thanks in Advance. |

I'm not surprised. An APAR would be automatically installed and activated, that command is to enable optional new functionality within the fix level.
I would theorize that you're getting the same error message for a different reason. If WMBv7 was still supported, you could raise a PMR. But it isn't, so you can't.

I wonder how you have gotten more than one content-type in your request message.

mqjeff - Thanks for reply!

I am not manipulating anything on the HTTP headers. compute node just calls the CopyEntireMessage function.
I cross checked the content type sent in the request by placing break point just before http request node and resulted with below headers. It has single content type header.
| Code: |
HTTPInputHeader
X-Original-HTTP-Command:CHARACTER:POST http://localhost:7801/b2b/service/ServiceOutbound HTTP/1.1
Accept-Encoding:CHARACTER:gzip,deflate
Content-Type:CHARACTER:text/xml;charset=UTF-8
SOAPAction:CHARACTER:""
Content-Length:CHARACTER:490
Host:CHARACTER:localhost:7801
Connection:CHARACTER:Keep-Alive
User-Agent:CHARACTER:Apache-HttpClient/4.1.1 (java 1.5)
X-Remote-Addr:CHARACTER:127.0.0.1
X-Remote-Host:CHARACTER:127.0.0.1
X-Server-Name:CHARACTER:localhost
X-Server-Port:CHARACTER:7801
X-Query-String:CHARACTER:CH=4 |

Is an HTTPInputHeader the right thing to send to an HTTPRequest node ?

I have rebuilt HTTPrequest headers for the request. But still no difference in the error which i am receiving it.
| Code: |
HTTPRequestHeader
Accept-Encoding:CHARACTER:gzip,deflate
Content-Type:CHARACTER:text/xml
Host:CHARACTER:localhost:7801 |
Note - My 3rd party url has basic authentication. Hence i have included username and password in properties as like below.
| Code: |
ContentType:CHARACTER:text/xml
IdentitySourceType:CHARACTER:usernameAndPassword
IdentitySourceToken:CHARACTER:myusername
IdentitySourcePassword:CHARACTER:myPwd
IdentitySourceIssuedBy:CHARACTER:
IdentityMappedType:CHARACTER:
IdentityMappedToken:CHARACTER:
IdentityMappedPassword:CHARACTER:
IdentityMappedIssuedBy:CHARACTER:

Are you still including the HTTPInput header... ?
Are you positive that the request is actually reaching the remote server and that the failure is there?

Hi Mqjeff,
I am not including HTTPInput header now. I have added HTTPrequestheader and removed HTTPInput headers by below snippet.
| Code: |
SET OutputRoot.Properties.IdentitySourceType ='usernameAndPassword';
SET OutputRoot.Properties.IdentitySourceToken = 'username';
SET OutputRoot.Properties.IdentitySourcePassword = 'pwd!';
CREATE NEXTSIBLING OF OutputRoot.Properties DOMAIN('HTTPRequestHeader') NAME 'HTTPRequestHeader';
SET OutputRoot.HTTPRequestHeader."Accept-Encoding" = InputRoot.HTTPInputHeader."Accept-Encoding";
SET OutputRoot.HTTPRequestHeader."Content-Encoding" = InputRoot.HTTPInputHeader."Content-Encoding";
SET OutputRoot.HTTPRequestHeader."Content-Type" = 'text/xml';
SET OutputRoot.HTTPRequestHeader.Host = InputRoot.HTTPInputHeader.Host;
SET OutputRoot.HTTPRequestHeader."Authorization" = 'Basic '||base64Encode(CAST('username:pwd' as BLOB CCSID InputRoot.Properties.CodedCharSetId)); -- I tried removing this line as well.
SET OutputRoot.HTTPInputHeader = null; |
It seems i can able to hit the request to server. I can see HTTP 200 in the HTTPResponse header.
| Code: |
HTTPResponseHeader
X-Original-HTTP-Status-Line:CHARACTER:HTTP/1.1 200 OK
X-Original-HTTP-Status-Code:INTEGER:200
Via:CHARACTER:1.0 xxx.xxx.com ()
Connection:CHARACTER:close
X-CorrelationID:CHARACTER:Id-734e4f5647d55c00ce1806008xxxe86a 0
Date:CHARACTER:Fri, 20 Nov 2015 16:46:43 GMT
Content-Type:CHARACTER:text/xml; charset=utf-8 |
If i am not wrong, the response coming from the server has some content-type duplicated which could not accepted by WMB7.0.0.8 and it routes to the failure terminal. |

Time to get out tools like Wireshark and see exactly what is coming over the wire?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Issue got resolved!!! 
Thanks mqjeff,Vitor and smdavies99.
Resolution - I have added below line in my esql.
| Code: |
| SET OutputRoot.HTTPRequestHeader."Authorization" = 'Basic '||base64Encode(CAST('username:pwd' as BLOB CCSID InputRoot.Properties.CodedCharSetId)); |
If i remove this line, i am gettting error saying

But i am not sure how that line is related to content-type.
I have cross checked few times by commenting and uncommenting the "authorization" in the requestheader.
Once again thanks for everyone.  |
