ICM_HTTP_CONNECTION_FAILED + web services

Hello Friends,
I am receving the following run time error CX_AI_SYSTEM_FAULT, due to The reason for the exception is:
Error (id=SOAP:1.023): SRT: Processing error in Internet Communication
Framework: ("ICF Error when receiving the response:
ICM_HTTP_CONNECTION_FAILED")
I am trying to access the web services, via my abap program..... and for that I have to create the virtual port for connection between the ABAP STACK and Internet ( web services)...
I have gone to scif, and then goto , port info, there for HTTP port was 8002, which I have assign as my virtual port for communication.... but still getting the same error...
Any idea, ??
Many thanks, and so nice of you...

Hello Raja,
Many thanks for your reply..... if you read my post then I am confident my problem will be solved ....
Actually I am using 7.0, and there I do not find any way to set the proxy settings in ICM.... however in sm59, I activate the proxy....
( before setting the proxy in sm59, I was getting the HTTP_FAILED error, but now I am getting the server not response error....)
Dont know how , and what to do now.... any tip ?
Regards,
Shah

Web service error handling (SOAP 1023 SRT: ICM_HTTP_CONNECTION_FAILED)

Hi there,
When consuimng our web service, sometimes we get the error "SOAP 1023 SRT: Processing error when receiving the response: ICM_HTTP_CONNECTION_FAILED" and this happens when we can't connect to the other system. The requirement is to automatically resend the transaction after +/- 10 seconds. Is there somewhere on the web service settings that will enable us to achieve this without having a background job running every minute?
Thanks.

Hello,
 
The first thing you should do is to check that your application server can reach the service your are trying to call. I suggest to try a:
 
telnet <remote_service_url> <remote_service_port>
 
from the command line of your server.
 
You should get a blank screen if your server reaches the remote server and something like connecting to <remote_service_url> if you don't.

How to connect to External Web Service? Error: ICM_HTTP_CONNECTION_FAILED

Hi all,
I have created an External Web Service, and I am trying to call the web service from SAP. I watched some tutorial and did everything like them, but I am getting this error:
SOAP:1,023 SRT: Processing error in Internet Communication Framework: ("ICF Error when receiving the response: ICM_HTTP_CONNECTION_FAILED")
Can someone tell me how to solve this problem ?
Thank you in advance

Your AS ABAP is unable to connect to the remote server, talk to your network admins.

ICM_HTTP_CONNECTION_FAILED and Web Services

Hello Experts,
I am consuming web services from ABAP program. For that i have created proxy object using SE80. Proxy is created successfully but while testing i got following error.
"return code 400,message "ICM_HTTP_CONNECTION_FAILED""
I have searched on on SDN but all the threads related to SAP XI. I got one relevant thread Re: SICF settings for creating a proxy in ABAP for external webservice but did not find entry in SICF for service.
Any help??
Thanks,
Prashant

Hi Lavaughn,
Try maintaining HTTP proxy setting using transaction SM59->RFC->HTTP Proxy Configuration. I suspect your WAS server also need to use proxy server for accessing internet.

Error testing external web service ICM_HTTP_CONNECTION_FAILED

Hi All,
I have created proxy class to consume external web service also created logical port but while testing the service through SE80, I am facing error "SOAP:1,023 SRT: Processing error in Internet Communication Framework: ("ICF Error when receiving the response: ICM_HTTP_CONNECTION_FAILED")" I have gone through many threads for similar error but not able to resolve the issue. I have tried various WSDL from samples given in sdn but still facing same error. Also tried to access any external URL through sample program as follows, but it gives same error while receive method (400 ICM_HTTP_CONNECTION_FAILED)
sample used program to call URL : gets dump with error(400 ICM_HTTP_CONNECTION_FAILED)

Error in consuming a web service

hi experts,
i want to communicate to a non SAP legacy system from SAP system through web services. in this process the legacy system has released a web service which i am supposed to consume in SAP system but when i try to create proxy object and i put URL, it gives me error as 'HTTP error (return code 400, message "ICM_HTTP_CONNECTION_FAILED")'. whereas when i create a web service in sap(crm) and try to consume it in sap(r/3) it easily allows me to create proxy object when i put the URL.
one thing i noticed is if i execute the report 'rswf_test_http' which tests http connection and give URL of web service created in sap it shows successful execution but if i give URL of legacy system web service it shows red signal with error 'HTTP-Receive: RC=400 ICM_HTTP_CONNECTION_FAILED'.
please help me on this.
thanks in advance,
sagar.

I am not passing any parameters to the method (it has no parameters). On the ColdFusion side I do not use i1 anywhere. I will check with the .net developer on Monday to see if he is using it anywhere in his code. If he is he is using in consistently as the only methods that work from his service are those that do not have an ID property. All services with an ID property give me the same error message.

Calling Web Service from a BSP

Has anyone successfully called one of the Google search engine web services from 6.20? Or any external, non-R/3 web service for that matter? When I run test connection on a RFC destination type G (HTTP connection to External Server), it returns ICM_HTTP_CONNECTION_FAILED message. I am using api.google.com for Target Host and /search/beta2/ for Path Prefix; all other fields are blank/default. I was able to setup the RFC destination for type H (HTTP connection to R/3 system) correctly and run the sample ABAP web service client program (from SAP Help which calls STFC_CONNECTION).
Any help will be appreciated.
Thanks, Pradeep

Does your company use an Internet Proxy? Have you setup the global or RFC specific proxy settings?
This is what we had to do. We were calling a psedo webservice in 620 via HTTP Client methods and we had to setup the Proxy settings.
See the following weblog for details:
/people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap
But keep in mind that even if you are able to make the connection that the WebService will most likely require a SOAP response and request. There are some ways to do this in 620, but it is a lot of development on your part and it is not forward compatible with 640. In 640 you can generate Proxy Classes - which makes calling external webservices very easy.

Incorporating web service in an ABAP web dynpro view

Hi,
I am trying to call an external web service to have its results displayed in an ABAP web dynpro view. I've seen various threads that are dealing with the same issue, but none of them seemed to have helped me (I am quite new at this so maybe I'm just having a slow beginning, please bear with me)
I'm interested in extracting information from a simple web service online. To this end, I went on www.xmethods.net and found a "quote of the day" service, which is practical because it doesn't even need input.
I am writing down all the steps I've taken, even if they seem trivial, because maybe my problem is the result of a silly mistake I'm not yet capable of noticing...
I am mostly following the instruction from here:
<a href="/people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap:///people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap
The SAP I use is the one on the SC7 system, seems to be ECC 6.0
After I created my package, I go on to create a Proxy Object, and when prompted for a WSDL source, I give the URL destination I got from xmethods.net: <a href="http://www.swanandmokashi.com/HomePage/WebServices/QuoteOfTheDay.asmx?WSDL">http://www.swanandmokashi.com/HomePage/WebServices/QuoteOfTheDay.asmx?WSDL</a>
Doing this I get an HTTP error (return code 400, message "ICM_HTTP_CONNECTION_FAILED") (others have had this problem, e.g. Calling Web Services from ABAP, but the answers offered haven't been much help to me)
and having no idea what to change or not change in SICF and other settings, I decided to save the file locally, and so I then created a Proxy Object by choosing the WSDL source as the local file I saved.
Telling me that multiple port types exist (SOAP, httpGet and httpPost) I picked SOAP. I can then see the properties of my Client Proxy Object, its structure with the classes and methods etc.
Then, following Thomas Jung's procedure, I went to create a logial port which I named QUOTE_PORT. When I do the F8 test he suggests to do, I get an error: SRT: Processing error in Internet Communication Framework: ("ICF Error when receiving the response: ICM_HTTP_CONNECTION_FAILED") which was predictable since I still haven't resolved that same problem above.
I then proceed to create a Web Dynpro Component. In that component, in the component controller's context, I created a simple node into which I added attributes which I created using the wizard -> Attributes from components of structure, and there I picked the structures that had just been created in my proxy object, each in its own node
I have three proxy structures generated: GET_QUOTE_SOAP_IN, GET_QUOTE_SOAP_OUT and QUOTES. This last one has two attributes which are STRINGs, the quote of the day and its author.
I then create a rather trivial view, whose context I have mapped to the component controller's context so as to have access to those "quote" and "author" attributes I just mentioned. The layout is simplistic at best, containing only two textviews, each one bound to its respective attribute.
Once the application has been done and tested, the output is a blank page. I'm hoping that this is only because of that ICM_HTTP_CONNECTION_FAILED error. Has anyone else had these problems when calling external web services? Is this the right procedure for displaying output?
Thanks and Regards,
Micol

Hi, sorry for the long reply time.
from work I do have proxy settings:
automatic configuration script: http://proxy:8083
proxy server for LAN: proxy / 8080
from home it's a proxy free connection.
In both cases I tried changing the settings in the SICF transaction, but it hasn't changed much.
With the HTTP error that I get, I get a long text on how to maybe solve it,
No connection to Integration Builder (only generic data visible)
Message no. SPRX081
In this long text, I have four tests to do in order to check the connection (as far as I can understand)
1. The address of the Integration Builder must be stored in the SAP system
=>Check/maintain with report SPROX_CHECK_IFR_ADDRESS
2. The HTTP connection of the ERP application server must function correctly
=>Check with report SPROX_CHECK_HTTP_COMMUNICATION
3. The Integration Builder server must be running correctly
=>Check with report SPROX_CHECK_IFR_RESPONSE
4. Proxy generation must interpret the data of the Integration Builder correctly
==>Check with report SPROX_CHECK_IFR_CONNECTION
The checks for 1&2 work okay, but I get errors for checks 3&4
"Integration Builder data not understood"
How can I go on from here?
Thx

Consuming Web Service from ABAP: ERROR_WEBSERVICE_RUNTIME_INIT

Hi fellows,
I have to make a call from SAP (CRM) to external system (via webservice) for this purpose I've setup a new Proxy-Object, uploaded the WSDL file (locally) and Created a Logical port.
In the Logical Port under the tab Call Parameter I've defined the URL of the web-service. I am also not able to upload the WSDL by selecting the option URL/HTTP due to error message "HTTP error (return code 400, message "ICM_HTTP_CONNECTION_FAILED")
Message no. SPRX090" so uploaded the file locally.
However, when testing the service, I didn't received a sucess message but:
<CX_AI_SYSTEM_FAULT>
<CODECONTEXT>Local</CODECONTEXT>
<CODE> ERROR_WEBSERVICE_RUNTIME_INIT </CODE>
<ERRORTEXT> Error when instantiating the Web service runtime (Error when initializing SOAP client application: ' error_text' ) </ERRORTEXT>
<LANGUAGE />
</CX_AI_SYSTEM_FAULT>
</cls:CX_AI_SYSTEM_FAULT>
What might be the Problem ?
/Manik

Vijay,
I've to make a call to External (non-sap) system --> pass some values --> (and then) get the returning parameters/values from the exernal system. The webservice is created in external system and here SAP will act as a client.
The system is SRM5.0, is it possible to use the RFC - XI soap approach in SRM 5.0 by maintaining the necessay configuration w/o involving XI system exclusively ? or XI is a MUST for this type of scenario ?

Consuming Web Service from ABAP

I'm using WAS 6.4 SP10.
I'm trying to consume a web service from our Intranet using instructions from ABAP256 from Teched 04.
I get an error when I try to create a Proxy object.
From SE80
Enterprise Services>Create>Proxy Object
URL/HTTP Destination:
http://server/ServiceGATP/ServiceGATP.asmx?wsdl
HTTP error (return code 400, message
"ICM_HTTP_CONNECTION_FAILED")
I've tried with ABAP web services and that works great. But no success with non ABAP Web Services.
From internet explorer the URL above seems fine. I can call it from a .NET application and it works great.
Any suggestions?
Could it be a system setup issue.
Regards,
Lavaughn

Hi Lavaughn,
Try maintaining HTTP proxy setting using transaction SM59->RFC->HTTP Proxy Configuration. I suspect your WAS server also need to use proxy server for accessing internet.

Hi James,
Thanks for the quick reply.
We've tried to call that web service from an HTML designed in Visual Studios with the same username and password and its working fine.
But on the BPEL console, we are getting the error as mentioned.
Also if you can tell me how to set the user name and password in the header of the parter link.I could not find how to do it.

),2)
= :P15_EV_LCL
then
span style="background-color:lightgreen"
|| TRUNC((

Unable to capture return values in web services api

At the time of login to web services if my server is down ,
it returns following error :
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
        at java.lang.String.substring(String.java:1438)
        at java.lang.String.substring(String.java:1411)
I want to capture this error so that i can try another server to login. how do i capture this error
Another place where i want to capture the return Value is when i look for a report on the server
rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
                           "@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
oInfoObjects = rh.getInfoObjects();
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
Here if the report is not there on the server , it returns a null handler exception.
but if i try catching it by checking my responsehandler is null like rh == null it does not catch it.
Any help will be appreciated
thanks

Ted : i have two cases
1)   server = server_st.nextToken();
    providerURL = "http://"server"/dswsbobje/services";
    sessConnURL = new URL(providerURL + "/session");
   Connection boConnection = new Connection(sessConnURL);
   Session boSession = new Session(boConnection);
EnterpriseCredential boEnterpriseCredential = new    EnterpriseCredential();
              boEnterpriseCredential.setLogin(userid);
boEnterpriseCredential.setPassword(pwd);
boEnterpriseCredential.setAuthType(auth);
SessionInfo boSI = boSession.login(boEnterpriseCredential);
I have got a list of servers running web servcies stored in my tokens. when i pass the first server name say " test:8080" and that server is down , i want to catch somewhere in the code above that it did not get the connection so that i can loop back and try with the second server say test1:8080
This is for failover purposes.
at present when i was trying to capture return value of boSI it breaks giving the error
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(String.java:1438)
at java.lang.String.substring(String.java:1411)
2nd case :
I am geeting reports from the server and scheduling them:
i run the following code which works fine if reports is there
rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
"@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
oInfoObjects = rh.getInfoObjects();
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
Here if the report is not there on the server then i should be able to catch from the response handle rh that it has got a null value.
but rh does not return a null value
the code ultimately throws a null handle at the following line
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
i am not able to catch the null value there also.
hope you got my issue.

How to allow access to web service running under ApplicationPoolIdentity

Hi All,
I have a WCF web service hosted in IIS 7 (or maybe 7.5, whichever comes with Windows server 2008 R2) using DefaultAppPool running under ApplicationPoolIdentity per Microsoft's recommendation. The web service needs to call a stored procedure to insert data
to a db. The web server is on a different VM than the database server. The db server is running SQL 2008 R2. Both VMs run Windows server 2008 R2.
When the web service tries to connect to db, it encounters this exception:
Exception in InsertToDb()System.Data.SqlClient.SqlException (0x80131904): Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
Here's the connection string in web.config:
Application Name=somewebservice;Server=somewebserver;Integrated Security=SSPI;Database=somedatabase;Connection Timeout=60"
How should I configure SQL security to make this work?
Thanks in advanced.

Thanks for the link Dan. Maybe I'm the one who cause the confusion :)
If I understand you(and Erland) correctly, you suggest using a custom, domain account for application pool identity. However, if we do that, our IT will need to maintain those accounts, and they don't want that. So I'm choosing a built-in account called
ApplicationPoolIdentity as the application pool identity, but it's not working. Network Service, on the other hand, works, but my boss wants us to follow MS's best practice.
What's puzzling is that according to this: http://learn.iis.net/page.aspx/624/application-pool-identities/, both Network Service and ApplicationPoolIdentity uses machine account to access network resource (like db in this case), but in my case, Network Service
works, but not ApplicationPoolIdentity.
Hallo Stephen,
with respect - it seems to me that only idiots are working at your IT ;)... It is absolutely useful to work with "service accounts" created within the domain. That's the only way to manage and control accounts!
If you want to "pass through" the identity of the web user (SSO) you have to check whether the app pool is set to "allow impersonate". As far as I understand the ApplicationPoolIdentity-function the app pool will create a unique user named as the service.
I assume that will not work with the connection to the sql server because this user is unknown.
Local Service will not work because it's restriction is located to the local machine.
Network Service will work because access to network resources will be available.
So my recommendation is to use a dedicated service account or impersonation:
