Consume webservice using HTTP adapter

Hi PI Experts,
Can we consume a webservice using a HTTP adapter?
If yes can anyone share some knowledge, how to do so?
Thanks & REgards,
Krishna

Hi Krishna,
I think this can be done using FLEX.(not sure).

Error in consuming webservices using ABAP

Dear Gurus,
I am trying to consume webservices using ABAP. We dont have XI installed and no java instance installed.
I created a customer proxy through SE80 and generated a proxy class by giving a WSDL link and also defined logical port. Traditionally followed the steps. But while testing webservices , I get a ICF error.
The error is as follows:
SOAP : 1:023 SRT : Processing error in internet communication framework ("ICF error when recieving the response ICM_HTTP_CONNECTION_FAILED)
Please let me know the cause of this error and solution to be provided.
I also tried to call the method from an abap program, But I get CX_AI_SYSTEM_FAULT exception.
Awaiting your replies.
Thanks in advance for your support and valuable time.
Thanks
Gurushanthi

Hi Gurushanthi,
It could one of several problems, examples:
- A firewall setting
- http communication out disabled by Basis team or
- The logical port wasn't configured correctly.
Try the suggestions in this thread to narrow down the reason (particularly the telnet test from the server):

Using HTTP adapter with no namespaces

Hi,
Is there anyway to use HTTP adapter when the provider does not accept the namespaces. The HTTP binding wizard requires a targetnamespace to be defined in the request and response xsds that we have to use.
Thanks & Regards
Siva

Bernd we are trying to do the same thing only with the soap adapter. I'm convinced that no one really knows how to do it. We can't even find an SAP CONSULTANT that has done it .. at any cost!
If you hear anything good .. please let me know - my email is [email protected]
I think the nightmare is coming in because when SAP bought the j2ee ( application server ) they never really have integrated it so it's very confusing if the settings need to be done on the ABAP side or the J2EE side via visual administrator. In addition most Basis guys are only experienced in the ABAP side and not the J2EE.

Can I get a response back when I use HTTP adapter

Hi ,
I am doing a integration between SAP and ThirdParty Product using PI 7.1.
The scenario is ThirdParty -> PI -> SAP ,using HTTP adapter between ThirdParty and PI , and IDoc adapter between SAP and PI.
So,its a HTTP sender and IDoc receiver.
So I was just curious to know if the IDoc posting failed in SAP ,can I send a response from SAP to Thirdparty regarding the failure along with some error message.
Thanks for your responses.
Venu

Hi,
It may lead to some timeout problems if you design your scenario as synchronous i.e sending response back to HTTP..
as SAP may take time to process idoc and need to provide response back to PI ..by that time the connection may become invalid and thirdparty may receive response as timeout error...
As anyway PI has the option of Alert managements..you can trigger the error mail to the third party recipients for letting them the status...

XI message with Attachment using Http Adapter

Hi ,
We are using XI/PI 7.0 with Sp09 and Sender Application is SRM and Receiver is Ariba MarketPlace.
We are trying to Send PO with Attachments like Word, PDF etc from SRM to Ariba using Https adapter and from SRM we are using ABAP Proxy. When I did the testing with out any special config, I was able to send the attachments (I can see word doc as part of the payload-attachment) to XI from SRM but this attachment is not going through https adapter from XI to Ariba?
I have read some posts on this but I could not find the answer for my situation. One of the solution is that we can use SOAP adapter but we don't want to use Soap for some reasons.
Please give your thoughts.
Thanks in Advance.

That is true.

That is not true. XI adapter (in fact we do not talk of an adapter) supports attachments.

This is true, ABAP or Java Proxy are like XI adapter. Therefore it supports attachments.

The online help is wrong.

I do not see another solution besides using SOAP adapter in so-called non-SOAP mode. Yes you have to reimport the certificates to J2EE stack.

3rd party to sap using HTTP adapter

Hi Folks,
I'm sending some IDOC to sap from the 3rd party. I have to use HTTP adapter as sender and IDOC as receiver adapter.
Can you please suggest me how to configure teh sender side. As I know there will be no such configuration for the sender adapter as it is HTTP then how the HTTP adapter will get the data sent by the 3rd party and how it will pass it on to the idoc adapter ?
Regards....

If you like to have more details about the http url

Scheduling of message using HTTP Adapter.

Hi All,
The scenario is SAP ECC to SAP PI to SAP MII, and we are using HTTP adapter on the receiver side.
The requirement is that, the messages should be sent to MII in the order in which ECC sends it to PI.
Can anyone please help me on how this can be achieved.
Thanks and Regards,
NehaSingh

Hi Neha,
If it is IDOC to HTTP scenario and you use EOIO also you will face a big problem.
It will not work. I have faced the same problem.
Suppose at a same time ECC genaretes 100 IDOC then then in intregration engine it may not reach at same sequecnce as IDOC no.
You can go with IDOC packageing in this case in ECC.
In ECC send the IDOCs as packages.
Also in PI create one Sender IDOC channel with package size.
then before your actual mappinng create a simple mapping program to sort the IDOC based on IDOC number. Then do the actual mapping.
Dont forget to create an Unbounded IDOC structure as source side in Mapping,

Is it possible to use HTTP adapter?

Hi All,
interface will be trigged by ECC to run once a day. The purpose of this interface is to update ECC exchange rates with the exchange rates file provided by the Central Bank of Brazil.
The file is available in the web site: http://www. XXXX and its name changes depending on the date.
The format is YYYYMMDD.csv. Example: 20100419.csv
The scenario will be Abap proxy <-> PI <-> website (Http / soapu2026 whatever) (Syncronous as the date must be sent to build the correct filename).
My main question is: how can I pick up this csv file from the website? Is it possible to use HTTP adapter?
Thanks,
Satya Kumar

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[]) {
       try {
          URL url = new URL("http://www.XXXXXXX.com/raj.txt");
          URLConnection uc = url.openConnection();
          BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));
          while (in.readLine()!=null)

Is it possible to call a SOAP webservice using HTTP POST adapter

Hello Experts,
Is it possible to call a webservice using a HTTP adapter with POST method? If yes, how?
Regards,
Diptee

No this will not work since you have additional SOAP information (i.e. SOAP envelope, security information) in addition to the payload. If you need a simple HTTP-Post for example, then you don't need SOAP, you can use the more simple http protocol without the additional features of SOAP.
Also refer to this link for differences: Difference b/w SOAP and HTTP

Generating Webservice using HTTPS in XI.

Hi Experts,
I have generated webservice in XI using http , and i have tested using infopath soap client, its working fine. I have generated webservice in XI using htpps using the same scenario, when i am testing using infopath as soap client and tested, its giving error, request is not hitting the XI system at all. do i need to configure any certificate in infopath or in XI server, please can anyone advice. i have configured HPPTS without client authentication in SOAP adapter.
Thanks,
Dhanush

Hi Experts,
I am not able to get exact answer after reading the sap.help.com, sap notes.
My scenario is RFC < ---> SOAP ( webservice) , i have generated webservice with the HTTPS and secured port of XI, When i copy and past in IE browser, its showing status is OK, but request is not hitting the XI system. what are things to be taken care at soap client and XI server side, do i need to install any certificats at client side or server side. please advice me.

Consuming webservices using CF8

I recently upgraded to CF8 and I’m not able to consume webservices from my dev edition on my personal PC.
I have tried making my own simple test webservice, but I’m not able to consume them using CF. (I’m able to consume the ws using .Net or Java, but not from CF itself).
I always get the following error:
org.apache.axis.ConfigurationException: org.xml.sax.SAXException: Fatal Error: URI=null Line=40: The string "--" is not permitted within comments.
This is the code I’m using:
<cfscript>
wsargs = structnew();
wsargs.proxyServer = "proxy";
wsargs.proxyPort = "8080";
ws = createObject("webservice","http://ws.fraudlabs.com/zipcodeworldUS_webservice.asmx?wsdl",wsargs);
</cfscript>
I know that the WSDL is ok since the WS works in .Net and Java. I also know that I can retrieve the wsdl using
<cfhttp method="get" url="http://ws.fraudlabs.com/zipcodeworldUS_webservice.asmx?wsdl" result="myRes" proxyserver="proxy" proxyport="8080"/>
So why do I get the “The string "--" is not permitted within comments.” error?
I know that
I get the same error for all ws I try to consume from CF, even simple test ws made using CF.
The ws work, because I can consume them using .Net and Java.
CFINVOKE gives me the same error
Thanks,
Olav, Oslo, Norway

Have you tried the other methods of connecting to a webservice?
For instance by tag
<cfinvoke
              webservice="http://ws.fraudlabs.com/zipcodeworldUS_webservice.asmx?wsdl"
              method="post"
              returnvariable="httpResponse">
                <cfinvokeargument name="parameters" value="<xmlToSend>"/>
</cfinvoke>
Or by building up the CFHTTP call directly
<cfhttp
            url="http://ws.fraudlabs.com/zipcodeworldUS_webservice.asmx?wsdl"
            method="post"
            result="httpResponse">
            <cfhttpparam
                 type="header"
                 name="accept-encoding"
                value="no-compression"
             />
            <cfhttpparam
            type="header"
            name="SOAPAction"
            value="http://ws.fraudlabs.com/zipcodeworldUS_webservice"
            />
             
            <cfhttpparam
                type="xml"
                value="#trim( orderXML )#"
                />
        </cfhttp>
I found fiddling around with all three methods of creating a webservice usually results in one that works

Consuming Webservice on HTTPS Port

Good day to everyone...
I have consumed webservice that had been published on normal HTTP port...Now the webservice has been published on HTTPS port...I have trouble consuming it...
What are the changes that I might have to make in the existing Portal Service?
I tried using the wizard in eclipse to create a new service with the HTTPS URL...but that did not succeed...
Any light?
Thanks in advance.

Hello John,
have a look at this thread: HTTPS and EP Web Services Checker Hope it helps you.

Invokation of Webservices using HTTP

Can I invoke webservices in SAP using HTTP instead of SOAP? If so How?

Hi Vijay,
yes we can do it with HTTP
Configuring the Receiver Plain HTTP Adapter
Use
The plain HTTP outbound channel is a service provided by the Integration Engine. The system is addressed when technical routing determines a corresponding communication channel for the logical receiver from logical routing. The system sends the payload of the message to an HTTP address using HTTP, without being enhanced with an envelope.
Integration
You configure the adapter on the Parameters tab page during the definition of a communication channel in the Integration Server.
Activities
The plain HTTP adapter gives the receiver system the following specifications:
Transport Protocol
HTTP 1.0
Message Protocol
XI payload in HTTP body
Adapter Engine
Integration Server
Addressing Type
URL Address
HTTP Destination
Specify the target host, service number, and path prefix including query string:
http://<hostname:port>/<path>?<query-string>
You can identify the target host (HTTP port) of a SAP Web Application Server using the ICM monitor.
Host and port of the HTTP proxy (optional if there is a firewall between the plain HTTP adapter and the receiver system)
Authentication data for the receiver system, see also: transaction Display and Maintain RFC Destinations (SM59)
Specify the RFC destination.
Parameters from the Communication Channel for Technical Routing
●      Content type (the entry text/XML is expected as default)
Specifies the content format (payload) that the message should have.
●      (Optional) header fields for the receiver-specific protocol
●      Select Additional Query String Attributes:
○       Sender party
○       Sender service
○       Receiver interface
○       Message ID
○       Quality of service
○       Queue ID
The queue ID is only required if the quality of service is EOIO.
●      Specifications for payload manipulation
○       XML code (default UTF-8)
Specifies the character set.
○       URL escaping
Presents the XML in a URL-enabled format.
Special characters that could be interpreted as control characters are replaced with escape characters (masked).
○       Prolog
Enhances the payload for particular servers (optional, see below).
○       Epilog
Enhances the payload for particular servers (optional, see below).
Adapter-Specific Message Attributes
●      To evaluate adapter attributes in the message header of the XI message, select Set Adapter-Specific Message Attributes.
●      If you want missing message attributes to trigger an error message, select Fail If Adapter-Specific Message Attributes Missing.
If the indicator is set and the header for adapter-specific message attributes or one of the set attributes is missing from the message, this leads to a system error (red flag).
If you do not set the indicator, and message attributes are missing, the adapter accesses information from the adapter configuration.
●      If you want to use an HTTP destination or URL set by the mapping, select URL orHTTP Destination.
(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 Missingindicator, 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.
The technical names of the fields are:
○       URL: TargetURL
○       HTTP Destination: HTTPDest
●      If you want to use HTTP header fields, select Apply HTTP Header Fields and enter the fields in Field 1 to Field 6.
The fields are embedded in the HTTP request under the names you enter here.
The technical names of the fields are HeaderFieldOne, .... HeaderFieldSix.
●      If you want to use URL parameters, select Apply URL Parameters and enter the parameters in the fields Parameter 1 to Parameter 6.
The parameters are included in the HTTP request under the names specified here.
The technical names of the fields are URLParamOne, u2026, URLParamSix.
●      If you want to save HTTP header fields from the synchronous response in the XI message header, choose HTTP Header Fields (Synchronous Response) and enter the fields in the fields Field 1 to Field 6.
The fields must have the same names as the fields that are also to be sent in the HTTP response.
The technical names of the fields are HeaderFieldOne,...,HeaderFieldSix.
●      The attribute namespace for the adapter is http://sap.com/xi/XI/System/HTTP.

RFC-to-SOAP webservice using HTTPS

Hi experts,
I have a RFC-to-SOAP (sync) and the URL of the webservice is using HTTPS. I'm not the owner of the webservice.
Encountered these errors
- for sender comm :
com.sap.aii.af.ra.ms.api.DeliveryException: Peer sent alert: Alert Fatal: illegal parameter
- receiver comm :
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Peer sent alert: Alert Fatal: illegal parameter: iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: illegal parameter
We are not using certificate authentication so I don't think that's the cause.
Have checked that the https is running ok for ABAP but I don't think that got anything to do with the errors. Is there something wrong with SSL setting for J2EE? If yes, how may I check?
Are there some parameters to be set up? In the RFC sender comm & SOAP receiver comm, I do not find any special settings for https.
I have read this link : http://help.sap.com/saphelp_nw04/helpdata/en/14/ef2940cbf2195de10000000a1550b0/content.htm. Is it necessary to set the Exchange Profile Parameters? My BASIS colleague is now checking it.
Thanks for reading and will appreciate any advice!

Thanks Prateek for the quick reply!
Re HTTPS certificate, do you mean the cert for my XI server or the cert from the web service?
I have tested calling the web service using SOAPUI and it works fine without using the cert given by the web service (which is expired anyway)...
