HTTP Receiver - Proxy

Hi,
I had to design a file----- XI -
HTTP scenario.
Say i am connect to a 3rd party with address 11.11.111.11 throgh the HTTP call.
But now i am told that a firewall wil be in place between XI and HTTP.
What does that mean ? do i still have to call the address 11.11.111.11 or some thing else ?
do i have to take any specific care in the HTTP receiver ?
Any help is highly appreciated.
Thanks,
Vignesh

There is nothing specific you need to do here. Just you need to add a firewall rule that will allow PI to post to this IP.
Give a check doing a ping test to this IP. If not successful contact your network people to solve this.
May be you require HTTPS based on your company security policies. For that you need to install SSL certificate on your PI box, generated from target system and create RFC destination on XI. Use this RFC destination in receiver HTTP

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

Issue with HTTPS in sender soap channel: HTTP 502 Proxy error

Hi
We have a situation where we are providing the target url in SOAP receiver channel dynamically.
This is a synchronous scenario.
Whenever we use the url starting with "HTTP" it works but on using "HTTPS" we are getting the following error "HTTP 502 Proxy error"
Kindly help us resolve this issue.

Hi Anurag
Have you tried to open the HTTPS url in the web browser?
Please check with 3rd party and find out whether the web service supports the HTTPS url or not.
Please check the doc below. It may help

Code 110 Reason Error in HTTP Receiver adapter

Hello
I am having proxy to HTTP Receiver scenario in which i am calling the target application URL through HTTP Receiver Adapter. This interface is async interface and hence i am not expecting any response from the target system.
When i execute my interface the target system receives data from XI but in SXMB_MONI it sets the status of the message as "Automatic Restart" with the error description as "HTTP client. Code 110 reason" in HTML Code area <SAP:Code area="PLAINHTTP_ADAPTER">ATTRIBUTE_CLIENT</SAP:Code>
This is causing multiple messages stuck in the queue and presently i am manually clearing all the messages.
i checked the quality of service of the incoming message which is correctly setted as Exactly Once.
Is there any configuration missing?
Thanks in advance.
Regards
Rajeev

Hi Rajeev,
1.)Check in SMICM if your HTTP service is running or not.
2.)If its running fine then you can check whether your SSL certificate is configured properly or not.
Also follow the below mentioned links :

Parameter in HTTP receiver adapter

Hey
My requirements are:
I am sending an XML to an external system. Documentation says: "XML should be in a parameter in your request called 'xmlInput'".
How do I actually put my XML in this parameter? Does this have anything to do with the URL Parameters in comm channel configuration?
I have configured a client proxy, http receiver adapter and a communication channel in sm59 and they work OK, but it seems as I don't send the XML in this parameter.
Appreciate your help!
regards Ole

Hey!
Thanks for your answers.
Nana, are you sure of this, that java proxy is the only way I can put the XML in a parameter? I only need to confirm this because there is no place in their documentation that this is stated explicitly, I have only been told this via their technical person...:)
I agree that this is a limitation of the receiving system, and I know that this system is not up to date as I can tell from what they are saying and their documentation.

Is it possible to debug "CL_HTTP_PLAIN_OUTBOUND" FROM HTTP RECEIVER ADAPTER

Hi All,
In my PI interface the data from R/3 ( using abap proxy ) is getting posted on a external server using HTTP receiver adapter .
I assume that it triggers this class when you run the HTTP receiver adapter -CL_HTTP_PLAIN_OUTBOUND
Please let me know how can i enable debugging for triggering this class.
Please let me know the steps to debug this class by triggereing from SAP PI system ( when we run the interface on PI system )
Regards,

Hi ,
i am not sure about this,i wolukd prefer developing JAVA Proxy or File Adapter . try this code it read the data from website, try in you stand alone application,it is able to read or not.
you will face two problems,you have to convert CSC file to XML it is not possible in HTTP Adapter,
import java.lang.*;
import java.util.*;
import java.net.*;
import java.io.*;
class URL2AC
        public static void main(String args[]) {

          URLConnection uc = url.openConnection();
          BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));
          while (in.readLine()!=null)

Receiver Proxy Generation error

Hi Experts,
As per scenario. (file to Proxy and Proxy to file)
I am created two namspaces like this
http://SAP/XI (for SAP)
http://SAPto/MQ (for 3rd party)
for all interfaces i have to do proxy to file and file to proxy ASY. so i created
message interfaces like this.
under http://SAP/XI   (for SAP)
         MI_OA_ABC
        MI_IA_123
   http://SAPto/MQ   (for 3rd party)
MI_IA_ABC
MI_OA_123
here i am given same name for inbond/outound interfaces
then i am trying to generate proxy (client) under SAP for proxy to file
I am getting bleo error
same as receiver proxy also
error:
Objects from other namesapces are missing unble to save"

Hi Srinivasreddy,
          U need to save & ACTIVATE the two namespaces.first check it that one.
         You are working with FILE to PROXY & PROXY to FILE scenarios.
FILE to PROXY: U can create one namespace for both file & PROXY that enough.
                        like PROXY to file also.

Citrix Receiver Proxy

Hi
Im trying to configure the Citrix Mobile Receiver Proxy on a ASA but cant get it to work.
The ASA got several VPN configured, both client, clientless vpn and L2L.
It looks like ASA are terminating SSL every time the iPad connects.
What could be missing here? And any good advice on how to troubleshoot appreciated.
ASA 5585 - OS 9.1(8)
Citrix Receiver - 5.8.3
Citrix config:
group-policy DfltGrpPolicy attributes
dns-server value x.x.x.30 x.x.x.31
vpn-simultaneous-logins 10
vpn-tunnel-protocol ikev1 l2tp-ipsec
default-domain value xxx .org
webvpn
customization value DfltCustomization
vdi type citrix url http://citrix.xxx.org domain xxx.org username CSCO_WEBVPN_USERNAME password CSCO_WEBVPN_PASSWORD
From Log Viewer:

I did some captures today and all I got is the outside capture with a RST,ACK back to my test client.
On the inside interface, going to the Citrix server nothing. Did check for both ASA inside IP and the Citrix server IP in diffrent ways (any->ASA, Citrix->any, etc)
Looks like ASA is not listening for, or understands, incomming Citrix traffic?
Edit:
Just saw this: Key size >1024 is not supported as of now.
All certificates on the ASA are 2048, probably the problem?
Cheers

Assign a dynamic value to a field in HTTP receiver header without IR part

hi experts,
I am doing a scenario in which i am to add a header field in http receiver, whose value will vary for each transaction. and the value will be same as sender file name.
But this all I am to do without doing Repository part.(i.e. No message interface and no mapping)
Is it possible? If yes help me out.
"Useful effort will be appreciated"....
Thanks

Not able to see 'Adapter specific' indicator in http receiver comm. channel

I am not seeing the Adapter Specific Message attributes indicator in http receiver adapter where one can set a dynamic URL. Anybody any idea? Thanks.

I have a fixed URL except that it should be formed with https instead of http. I guess the default http is used as there is no where in the communication channel to select https. I am able to invoke the https url through browser but through http receiver adapter, I get error 'http client code 110 reason'. I see in other blogs that this is due to https not enabled in the J2EE engine. But for outbound why should that matter? As long as the target URL is set to accept https, I should be able to sent the message as long as the URL gets formulated starting with https. If it was SOAP adapter, the entire URL can be entered so no issue, but with http adapter is there a way to specify entire URL including the https:// ? Thanks.

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.

hello michal,
yes, i did. i took the information from http://help.sap.com/saphelp_nw04/helpdata/en/43/64dbb0af9f30b4e10000000a11466f/content.htm and tried to put some special information to URL. nothing to see.
is it mandatory to use a mapping to fill the URL parameter fields, isn't it??
i am using a port sniffer to see the URL and the fields (parameters) in it.

HTTP Receiver interface returns with error code 110

Hi All,
We are posting the document from XI to a external server as HTTPS request.
We are able to sucessfully post the request to external server using HTTP destination as address type but not able to post sucessfully with URL as address type.
Here goes the details -
We are able to post the HTTPS request successfully on the external server using the HTTP destination as address type in HTTP receiver adapter setup.
When we setup address type as HTTP destination , we need to provide the following details -
IN SM59 , Connection type G
Target Host : host name ( with out "https://" as prefix)
Service No : 443
Path prefix : query string
SSL : Active
Certificate : Select the certifacte from the client certificate list.
We can post the request to external server using URL as address type in HTTP receiver adapter setup.
When we setup address type as URL , we need to provide the following details -
Address type : URL Address
Target Host : host name ( with out "https://" as prefix)
Service Number : 443 ( HTTPS port setup on XI)
Path : query string.
When we post the same request as we did with HTTP destination as Address type , we are getting a HTTP response code as failure HTTP response code 110
Please find the details about the return code -
If a cache returns a stale response, either because of a max-stale directive on a request, or because the cache is configured to override the expiration time of a response, the cache MUST attach a Warning header to the stale response, using Warning 110 (Response is stale).
110 Response is stale
MUST be included whenever the returned response is stale.
Please find the error message from SXMB_MONI

Hi All,
Is some one can confirm that - We can use HTTPS with Address type as URL address in HTTP receiver adapter setup.
I can confirm that using HTTP destination as Address type in HTTP receiver adapter setup we can attain HTTPS communication with external server.
If some one who has tried HTTPS communication using HTTP receiver adapter using URL address as Address type can guide me what are the steps need to be done.
Address type is a parameter in HTTP adapter setup .
