Dear All,
while sending web-service request to external system through HTTP request node , some times the response comes through error terminal but the response message is in BLOB format , i need to parse the response from BLOB to XML . i tried with RCD node but it didnt work . also i tired to cast it to CHAR CCSID 850.but it shows as a HTML message. Kindly give some knowledge if possible.
Thanks

Did you try change the response parse type to XML,XMLNSC .. for http request node...
and BLOB message is a Hexadecimal code i tried to convert that to xml by cast with 1208 by that didn't work so just try to change the response parse try |

Are the characters in the BLOB really XML?
Why not write the BLOB to a file or a queue and see what sort of things are really coming back.
It might be that your external service is being accessed via a load balancer of some sort and that one server you get to use is sending back bad info.
In order to go back to the external service supplier you need real data to back up your claim.
Once you can see the real HEX codes you can see if there are spurious characters or invalid xml or any number of other things.
IMHO, this is what systems integration is all about. But you need patience and a methodical approach to problem solving. Then you will get to the bottom of it sooner.

did you keep copying the data until you got a bad message?
once you get that you can really compare the good with the bad.
It might be something as trivial as a bad header.
For example your good message might contain this
| Code: |
<?xml version="1.0" encoding="utf-8"?>
|
and the bad ones might contain this
| Code: |
<?xml version="1.0" encoding="iso8859-1"?>
|
And the message might really be written with CCSID 1208 and/or the data might contain a Euro symbol which isn't present in the ISO8859-1 character set.
Just saying that the data contains the whole soap message may well not be the whole story.
When you get a parsing error does the exception list (at the very bottom) give an reason where or indication as to why it failed?

HI all,
sorry for the late reply . I have captured the http response header through trace node
----------------------------------
(0x01000000:Name):HTTPResponseHeader = ( ['WSRSPHDR' : 0x120569710]
(0x03000000:NameValue):X-Original-HTTP-Status-Line = 'HTTP/1.1 500 Internal Server Error' (CHARACTER)
(0x03000000:NameValue):X-Original-HTTP-Status-Code = 500 (INTEGER)
(0x03000000:NameValue):Date = 'Thu, 04 Jun 2015 03:36:43 GMT' (CHARACTER)
(0x03000000:NameValue):Content-Length = '1150' (CHARACTER)
(0x03000000:NameValue):Content-Type = 'text/xml; charset=UTF-8' (CHARACTER)
(0x03000000:NameValue):X-Powered-By = 'Servlet/2.5 JSP/2.1' (CHARACTER)
--------------------------------
in the body i am getting response in blob , i have not mentioned the blob message in this post.
----------
(0x01000000:Name):BLOB = ( ['none' : 0x11997a430]
(0x03000000:NameValue):UnknownParserName = '' (CHARACTER)
(0x03000000:NameValue):BLOB = X' ' (BLOB)
---------------------
since the system is sending http response as "500" it is routed to error terminal , please share your suggestions

so the external system that you are calling is falling over/failing to process your request.
Perhaps you should as the external service provider why they are sending a 500 error back to you. They should know why (or at least I hope so).

Than you for your support, I have already reported this issue to the external system team, and i think the external system is failing to fetch required data from there DB , so it is sending http"500" .
I hope they will be fixing this issue .

One of the essential bits of thick skin that you have to grow is highlighted by this problem.
Because Broker/IIB is at the centre of things everyone points the finger at the Broker/IIB support team when anything goes wrong.
Being able to say definitively that 'it ain't broker' is IMHO key to being able to rest easy at night (due to the thick skin)
On the flip side, being able to say 'yep, this is our problem' is also a key skill.

Always blame the network guys, until you can prove that it's the application team...
