PI 7.11 - Sync HTTP receiver adapter with response XML file

Hi
We have a File to HTTP scenario in which we need a sync HTTP interface. We send a file to the HTTP address and receive a XML acknowledge. As I read in this forum: sync HTTP interfaces are not possible with the "standard" HTTP adapter. So I found an entry which recommended to use the SOAP adapter instead.
I configured it:
- Do Not Use SOAP envelope
- modules: RequestResponseBeans, CallSapAdapter, ResponseOneWayBean
If i use this scenario, i get following error in the RWB - Message Display Tool:
Delivering the message to the application using connection SOAP_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.lang.NullPointerException: while trying to invoke the method com.sap.engine.interfaces.messaging.api.Message.getMessageId() of an object loaded from local variable 'message1'.
I testet this scenario using CURL and it worked properly. Should this kind of scenario work with the SOAP adapter or do I need to buy/develop an own adapter? Is in NW7.3 possible to configure sync HTTP scenarios?
Thanks in advance
Michael

Hi
actually i use a simple HTTP receiver CC with the setting "XI Payload in HTTP Body" to send a XML datafile to a webpage (java servlet). This part works fine by now. But, this servlet would also send back a status information to the state of the received datafile, which I like to catch.
e.g. HTTP response from the servlet (catched using CURL):
HTTP/1.0 403 Forbidden
Server: Apache-Coyote/1.1
X-Powered-By: Servlet 2.4; JBoss-4.3.0.GA (build: SVNTag=JBPAPP_4_3_0_GA date=200801031548)/Tomcat-5.5

HTTP Receiver adapter with post

Hello,
I have following scenario.
XI (http receiver adapater) -
> 3rd party web based application.
The 3rd party application expects XI payload to be part of URL with POST Method.
When HTTP receiver adapter sends request to 3rd party application, the URL looks like as follows.
http://myserver:6789/myapplication/name1=value1&name2=value2&.....&name27=value27
I looked at HTTP receiver adpater document on SDN. I see some attributes such as headerfiled1, headerfiled2..... headerfield6 and urlfield1....urlfield6. I have about over 25 fields to be passed with URL.
Now I have following questions.
1. How to make XI payload as name value pairs and part of URL.?
2. I think the default for http adapater is GET, How to configure http adaper to use POST?
I appreciate your help.
Thank you,
Balaji

> 1. How to make XI payload as name value pairs and part of URL.?
You should create the whole URL in a user defined function in mapping.
> 2. I think the default for http adapater is GET, How to configure http adaper to use POST?
HTTP adapter (and SOAP adapter) use HTTP POST. GET is not supported.

HTTP Receiver Adapter - delete ?xml version="1.0" encoding="UTF-8"?

Hi,
Is it possible to delete the part below when sending an HTTP request through HTTP receiver adapter without any java/abap/xslt mapping?
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_SELL xmlns:ns0="http://test.com/Sell">
Thanks
Arman

Hi,
<?xml version="1.0" encoding="UTF-8"?>
Specifies that the given message is xml
<ns0:MT_SELL xmlns:ns0="http://test.com/Sell">
Specifies its a MessageType of the payload, without this that message is not identifies and is not processed. Its manditory to have these. Other wise error will raise.

HTTPS Receiver Adapter with POST and query String

Hi there,
we are currently running a http connection with an external partner. We use the plain http adapter to send documents.
Now we want to secure the whole thing and switch to https.
Currently we solely use the comm. channel in the directory. In the URL we include the required query string (http:/xxx/yyy<b>?msgtype=order</b>)
As I understand, the only way to use httpS is to use a RFC Dest. Type G in sm59.
But I am not able to add a query to the url there.
I guess that it is not an option to ask our partner to search the posted document for parameters. We were already happy that they were able to do it like we have it.
Does anyone has an idea how we could include a query in the url or give somehow the partner explicitly the info about the message type we send?
Thanks in advance,
Helge

Hi Helge,
as far as I know this should be possible with SP16 by using the settings in the adapter configuration.
We had this requirement, but with SP15 it isn´t possible.
Have a look on the documentation
http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm
Chapter Adapter-Specific Message Attributes
There you can use up to 6 URL Parameters. I never used it, if you have SP16, try it.

Thomas

HTTP receiver adapter: dynamic configuration

I was told that if I have a URL and some parameters, I can use a sync HTTP receiver adapter to call a site.
I know this can be done using some kind of dynamic configuration, but I am not familiar with this adapter.
The most important question here is that I need to know if this can be done throw PI, so my question is:
Is there a parameter limit in the HTTP adapter? If so, what is the quantity of parameters that I can give to the adapter?

for the ASMA parameters you can use for the HTTP receiver adapter check
Configuring the Receiver Plain HTTP Adapter - http://help.sap.com/saphelp_nw04/helpdata/en/43/64dbb0af9f30b4e10000000a11466f/frameset.htm

How to set HTTP header field "cookie" with http receiver adapter?

Hi,
I am using http receiver adapter (not axis) in a scenario. I could not set a parameter with key cookie in http header. Is there some kind of restriction to set it? I am able to set others like connection and create custom fields using ASMA and dynamic key configuration via UDF on mapping.
Could you please comment on, is cookie http parameter special or noneditable by PI's http adapter? I am looking for a solution without editing any abap code...
Regards,

I believe it is possible since axis adapter provides very same functionality. Let me summarize my scenario may be it helps:
I am trying to call series of webservice lets say in a BPM. First service (login service) will provide me with a session id (in http header with key Set-Cookie) then I will call another service which has that session id in its http header with key cookie then I am going to logout. So I am testing the second part now, but it doest let me send cookie http header parameter.
I hope I clarified a bit more my problem.

HTTP Receiver Adapter payload as single line plain text with out any tags.

Hi PI experts,
I have a strange problem in http receiver adapter.
Sender RFC (SAP) Receiver: HTTP.
Receiver system expects the output from XI in the below format in a single line plain text with out any tags in the payload. and the content type should be application/x-www-form-urlencoded
Group=Test&Sentinel=Web%20Server&Facility=5345&Order Number=XT-XWHM-Y-NA&Serial Number=123456&@LABEL_QUANTITY=5&@LABEL_NAME=111114_Q
Is there any way to achieve this using http receiver adapter. Business is not ready to accept the output from XI not even in a single element instead they only need it as a JUST a plain text.
Appreciate early response on this.
Thanks in Advance,
Jitender

Dear Ola,
Could you elaborate how you achieved in catching the response data from the receiver in case of HTTP receiver adapter?
The target service is not a WebService but some python script that must to receive some paramters via POST request.
HOW can I post this parameters?
Here you entered the fields of the message type of the request in the header parameters of the receiver adapter? Thats fine.
But what about the message type and vice versa of the response from the receiver?
Regards
Rebecca

How to trace HTTP receiver adapter error

Hi All,
My scenario is to send PO details to vendor site (HTTPS URL). MY SSL configuration is complete and I have used the SSL certificates in RFC destination of type 'G'. When I test RFC destination connection, it gives me the correct response as '200'.
This RFC destination is used in HTTP receiver adapter of XI to connect to site and post PO xml document. It is passing successfully through Integration Server, as I get success flag in 'SXMB_MONI'. But, it is not reaching our vendor's site.
Can someone help me, with what's going wrong, or how can I trace the error.
Thanks & Regards,
Amit

Hi Sadhna,
It's a B2B scenario, where my sender is configured correctly and the receiver as well.
In sxmb_moni, I am getting successfull status. But, it is not reaching receiver.

HTTP Receiver Adapter : Dynamic URL

Hi,
I have a scenario where I wish to build a dynamic URL for the HTTP Receiver Adapter. The URL will contain a customer number which is present in the mapping.
The help seems to suggest that this is possible :
<i>If you want to use an HTTP destination or URL set by the mapping, set the URL or HTTP Destination indicator. (The indicator displayed depends on the Addressing Type you selected above). If you set the indicator, the URL or HTTP destination set dynamically is called by HTTP.
If the message header does not contain the URL or the HTTP destination, and you have set the Fail If Adapter-Specific Message Attributes Missing indicator, the XI message is set to status System Error. If you do not set the indicator, the URL or HTTP destination defined statically in the communication channel is used.</i>
However, it is not very clear where the URL needs to be set dynamically.
Does anyone know how to achieve this ?
Cheers
Colin.

hello to all,
We have a unique issue with one of our customers that is limited to 100 character URL. The current url is http://mycompany.com/sap/xi/adapter_plain?namespace=urn%3Agoodyear%2Ecom%3AAIT%3AInventoryCheck&interface=AITInventoryCheck_Abs&service=HTTP_AIT_InvChk&QOS=BE&sap-client=010&sap-language=EN
Is there a way to have a URL like
http://mycompany.com/sap/xi/adapter_plain?namespace=urn%3Agoodyear%2Ecom%3AAIT%3AInventoryCheck
and then somewhere in the process add... &interface=AITInventoryCheck_Abs&service=HTTP_AIT_InvChk&QOS=BE&sap-client=010&sap-language=EN
So the data comes to an F5 through the DMZ to the SAP webdispatcher then to the SAP XI system.
Any ideas if this is possible or how you could start with a shorter URL?
Thanks,
Dede
