How to consume WEB SERVICES from ABAP ??

Q: How to consume WEB SERVICES from ABAP program??
     the point here is i am using SAP release 620 and the creation of proxy is out of scenario
     and also no XI.    Its only through ABAP program i need to consume one web service (its a HTTPS one ),
    Using cl_http_client... i tried it but i am totally confused of whats happening ???
Req some senior ppl advice on the same/approach.
any hints will suffice my way of approach...!!!
Please do put in your valuable advices..!!
Thanks in advance..!!!!

Hello Srinivas,
Following is the code for calling web service:
data: client type ref to if_http_client,
      host   type string value 'server url',
      service type string value '8080',
      path type string value '/sap/public/ping',
      errortext type string,
      proxy_service type string,
      scheme type i value 1.
call method cl_http_client=>create
exporting host = host
        service = service
     proxy_host = host
   proxy_service = service
   scheme        = scheme
importing client = client
exceptions
    argument_not_found = 1
    internal_error     = 2
    plugin_not_active = 3
    others             = 4.
case sy-subrc.
when 0.
     write 'Server reached successfully'.
when others.
     write: 'sy-subrc =', sy-subrc.
endcase.
Once you got the client object you can call following methods:
"Set the requrie URL for the web service you want to call. This is not WSDL anyway!!
cl_http_utility=>set_request_uri( request = client->request
uri =' url 2 be called ').
*Then you can call send method with proper inputs for sending request to WS
CALL METHOD client->send
Then you can use receive method for getting the response
CALL METHOD client->receive
*You can get last error in case of exceptions
CALL METHOD cl_http_client=>get_last_error
*Close the client object
CALL METHOD client->close
For more information on full code refer my link in previous replay.
Thanks,
Augustin.

Windows authentification while consuming web service from ABAP

Hi All,
We are consuming web service from ABAP, we have created client proxy in SE80 and configured logical port in LPCONFIG.
This one was working fine. Now we have added windows user authentification to access this service.
Now when I'm trying to regenerate this proxy in R/3 it is asking for user and password. When I enter these details this one is not working.
If I access this service direcly from internet explorer and I enter same user and password then I would able to access this service.
Could you please let me know how to handle this.
Regards
Vikram

The dialog that is produced by HTTP Destination object of the logical port is designed only for use within Classic Dynpro applications. There is no prompt produced when running in Web Dynpro. If possible assign a generic user within the logical port definition and this will be used automatically by all users.

Consume web service in ABAP proxy with SOAP header

Hi Thomas ,
I am trying to consume web service in ABAP . I have followed the procedure from one of your web blog <a href="/people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap a Developer's Journal Part XIV - Consuming WebServices with ABAP</a> . (640 release).
I need to pass SOAP header along with SOAP body. As you mentioned I have used if_wsprotocol_ws_header interface to pass header but it is still failing.
Please see below code and please give some direction to fix the issue.
1.Create ABAP proxy for WSDL (http://ws.strikeiron.com/SwanandMokashi/StockQuotes?WSDL). It has created structures only for SOAP body.
2.Create Logical port
3.Create following program to call proxy
REPORT zproxy.

        xml_root = xml_document->get_root_element( ).
        xml_element ?= xml_root->get_first_child( ).
      add header element by element to SOAP header
        WHILE NOT xml_element IS INITIAL.
          name = xml_element->get_name( ).
          namespace = 'http://swanandmokashi.com' . "xml_element->get_namespace_uri( ).
          IF NOT xml_element IS INITIAL.
          ENDIF.
          ws_header->set_request_header(
                      name = name
                      namespace = namespace
                      dom = xml_element ).
          xml_element ?= xml_element->get_next( ).
        ENDWHILE.
      ENDIF.
    ENDIF.

<i> is there any other way to consume web services in ABAP</i>
you can use cl_http_client class to make your program to act as http client and post the soap message too webservice. This way you dont need to generate proxy, but you should know the soap message format.

How to consume web service in Agentry in SMP 3.0

Dear All , I am using web service in Agentry to retrive data but could not able to fetch it . I have made connection with HTTP-XML for consuming webservices. and also give proper information in Agentry.ini files Ex : [HTTPXML-2] name=HTTP-XML Back End authenticationCertificateStore=MY authenticationCertificateStorePassword= authenticationCertificateStorePasswordEncoded=false autoDequote=true ;baseURL=http://localhost:81 baseURL=http://sapes1.sapdevcenter.com:8080/sap/opu/odata/iwbep/gwdemo/ basicAuthenticationPassword=123456 basicAuthenticationPasswordEncoded=false basicAuthenticationUserID=P1466405733 constantsFile=httpxml_sd.ini enableAuthentication=false enablePreviousUserAuthentication=false httpConnectTimeout=300 httpReceiveTimeout=300 httpResolveTimeout=300 httpSendTimeout=300 listenOn= timeout=300 timeZoneName= useSSL=false xmlAllowXSLTScript=true xmlNamespaces= xmlResolveExternals=true xmlValidateOnParse=true for more information i have attached agentry XML screen shot as well . Can you please guide me how to consume web services in Agentry correct way ? Note : Currently i am using standard netweaver demo web services . Thanks & Regards , Kunal Varaiya
Tags edited by: Michael Appleby

The XML Steps URL will be added to the Agentry.ini BaseURL. So you dont' need the full URL on the step.
So when Agentry Runs the step to call the backend it will go:
<BaseURL>/<Step's URL>
This way if you need to change the base URL, IE, going from Dev to QA to Production Server you only need to change the Base, and not go into every step and update it.
URL: This attribute contains the URL to which the Agentry Server will make a request. This value will be appended to the value configured as the base URL for the HTTP-XML system connection. This base URL is configured within the HTTP-XML system connection configuration options for the Agentry Server. Proper use of both this base URL option and the URL entered in the requests of the step definitions can support portability for the application, with the base URL being the implementation-specific portion and the step’s URL being the portion not likely to change for the same back end system from one implementation to the next.

Other then performence is there any other disadvantages like security,etc for consuming web services in ABAP using ABAP proxy?
I really appreciate if some one provide the more details(Pros & Cons ) regarding cosuming web services and I also want to know is there any other way to consume web services in ABAP.
Thanks.

Problem at Consume WEB Service in ABAP

hello!!
I tell them my problem, is to create a web service from the SE80, which could be used properly.
Then there was a change of server, which migrated to the developments and the web service is recreation, but this can not be consumed.
now I need help, is where do I indicate that the basis so that they can return to consume web services, what services or settings should be activated.
any suggestion or help are welcome.
The ECC system is a 5 AS ABAP only.
from now, I appreciate any help or guidance I can get.

What is the problem? Are all the services active in SICF for web services and how is the web service being consumed is it through a wsdl file ?

Wrong data when consuming web service via ABAP

Dear all,
we tried to consume a web service via ABAP and used one of the various existing how-to papers from the internet in order to develop everything.
The development was not that difficult, but when we now execute our ABAP, we noticed that
- the first 100 returned rows from the webservice are completely correct
- then we receive 10-15 completely incorrect rows (empty fields, redundant lines, etc.)
- the rest of the data (60 records) is correct again
As we nearly all objects have been generated automatically via SE80, I do not really know where this problem might come from. We double checked the original data and there everything is correct.
Any ideas?
Thanks for your feedback,
Andreas

Consuming Web Service from ABAP Web Dynpro

I have written program to consume KM Web Service through ABAP as well as ABAP Dynpro in SAP R/3 by calling Consumer Proxy.
When I run the program from SE38, it prompts me for user-id & password. If I pass KM Server user-id and password I am able to execute the web service successfully.
However, while I execute the same code through Web Dyn-pro , it does not ask for user-id and password & terminates with CX_AI_SYSTEM_FAULT : SOAP:1,007 SRT: Unsupported xstream found: ("HTTP Code 401 : Unauthorized")
I have created a Logical Port in R/3 & I am using this Logical Port while creating an Object of Consumer Proxy.
Kindly let me know how to resolve this issue.

The dialog that is produced by HTTP Destination object of the logical port is designed only for use within Classic Dynpro applications. There is no prompt produced when running in Web Dynpro. If possible assign a generic user within the logical port definition and this will be used automatically by all users.

How to use web service with ABAP Web Dynpro

Hi.
do you know, how to web service with ABAP Web Dynpro?

Hi,
If you have a webservice ready with you then you can generate a proxy from SE80 and you can use that. You just have to create a port and assign to that generated proxy(CLASS) and you are good to go.
Let me know if you need more information.
Thank You,
Gajendra.

To consume web service in ABAP is it required that server should be XI.

Hi ,
I am trying to connect to a webservice from netweaver 7.0 systemand it gives an error " Not configured as integration engine". Is it required to have integration engine to consume web service.
Sanjay

Hi Sanjay
You can consume webservices in ABAP but its better to use XI in mid to avoid point to point communication. Using XI you can have a central hub for all services you consume or publish
