Proxy object to consume web service

Hi,
I want to consume a web service in ABAP (on a WAS 7 box) and have read many blogs/posts about using a proxy object.
I've gone to SE80 and selected create a service consumer, enter the URL for the WSDL.
The generation of the proxy fails with the following messages;
Proxy-Generierung: Fehler aufgetreten
Exception occured in the library handler
not implemented
There is no other help or information in these errors.
Does anyone have any ideas on what is causing this and what I can do to successfully generate a proxy to consume the web service ?
Cheers
James

Hello Torsten,
It seems that the Web Service You are going to consume is a SOAP 1.2 one.
It is apparently making use of the so-called "SOAP Web Method Feature" which is part of the SOAP 1.2 specification (see [Web Method Feature (W3C)|http://www.w3.org/TR/soap12-part2/#WebMethodFeature]).
Unfortunately, SOAP 1.2 is, to the best of my knowledge, not supported as yet by the SOAP Adapter in SAP NW 7.0 / 7.1. That leaves You, in theory, with one of the following options:
- It might be possible to consume that service with the help of Axis framework (see [Using the Axis Framework in the SOAP Adapter|http://help.sap.com/saphelp_nw04/helpdata/en/45/a4f8bbdfdc0d36e10000000a114a6b/frameset.htm]). SAP Help states that with the help of the Axis framework SOAP 1.2 can be used. However, there are no further details on that subject, especially whether Web Method feature can be utilised (btw - has anyone tried this?).
- Ask service provider for a SOAP 1.1-compatible WSDL.
- Attempt to reverse engineer the SAP SOAP proxy so that it is capable of consuming a SOAP 1.2 Web Method-based web service (has anyone done this before?).
Would You be so kind to post whether, and how, You were able to consume this web service?
Kind regards

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.

Pros & Cons for consuming web services in ABAP using ABAP PROXY

Hi,
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.

 is there any other way to consume web services in ABAP
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.

Consuming Web Service - Proxy Generation Terminated

Hello all,
I have recently been exploring the capabilities of consuming Web Services from ABAP and have run into some issues.
When I generate the Client Proxy from different WSDL files, I am frequently getting these two errors:
Proxy generation terminated: "mixed content" not supported
Proxy generation terminated: WSDL error (<extension> not supported)
Is this just a limitation of ABAP? If I get these errors, is there any way to use the Web Service?
Thanks in advance!

Hi, had the same issue. try to rename the file to .xml ending.

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.

Consuming Web Services with ABAP - WSDL

Hi All,
I Want to consume web service in abap, i found lot of documents,Here i am having data in the internal table i need to pass

Hi Miguel,
I have not heared about SPROXY, Here i found some code,which calls a web service method and where it is from.
when i double click on my proxy it shows me some method.IF_PROXY_BASIS_INTERNAL~CREATE_FRAMEWORK
this is the one web service method. and i meed to pass the internal table data to WSDL file.

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.

Error running demo PL/SQL consuming web services

I downloaded and installed the code from:
http://technet.oracle.com/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html
on Oracle 9i version 2 (on both Windows and Solaris).
But I got the following error running the local time
demo:
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1022
ORA-12545: Connect failed because target host or object does not exist

The error occurs on this line:
http_req := utl_http.begin_request(url, 'POST','HTTP/1.0');
Can anybody tell me what I do wrong? Thanks a lot!
Also, is there any alternative ways to consume web services
using PL/SQL only? Many thanks!

Best practice for consuming web services

Hi
we are consuming web service in orchestration by "Add Generated Item".By using this option it creates 1 orch,1xsd file and some bindings.
we have different projects for schemas,maps and orchestration under our solution in visual studio.
Now i need to know that what will be the best practice for consuming web service in orchestration i mean in which project should i use "add generated item" (in orchstration project or in schemas project) coz it generates both 1 orch and 1
schema.
thanks

From a service orientation perspective you should abstract the service artifacts from the other artifacts. Otherwise it will be very difficult to update the service interface without affecting the other artifacts. For example you don't want to have to redeply
your entire application if only one field changes in the service you consume.
So I typically generate the items, remove the unnecessary stuff, and put them in a separate project.
Depending on the control you have over the services you want to consume, it would even be better to create another layer of abstraction. By that I mean create your own interface (schema) and map that one to the one the service exposes. This basically
is only necessary if you consume external services that are beyond your control. By abstracting the interface it exposes, you limit the impact of changes of that interface on the rest of your system. All changes are abstracted behind your own interface.
If you consume internal services, you can probably control the way the interface is defined. In a service oriented world all internal services expose a well known interface, based on the domain objects you have within your organisation.

Consume WEB Service in ABAP

HI
I am consuming web service WSDL file in ABAP using client proxy concept. But every time i execute the program system is
asking for portal user name and pwd. where can i put user name an pwd so that system can take it directly from there
during run time.

Yes,
There is a place in SOAMANAGER to put userid and pwd for portal user. and this works.

Consuming Web Services in SSIS Script Task

Hello
Sorry for my English, I' ll try to explain my problem.
I am new to SSIS. Using this article http://blogs.msdn.com/b/dataaccesstechnologies/archive/2010/01/28/consuming-web-services-in-ssis-script-task.aspx I have tried to consume web service.
1. I have created proxy class using VS Command Prompt
2. A have added proxy class to Script Task
3. But when I want to create the instance of the proxy class, it can be accessed from the ScriptMain.cs.
I will be very pleased for the help!

perhaps you missed this step:
--> Modify the code and add Credentials before calling the web method:
Public
SubMain()
Dim
ws As NewService1
ws.Credentials =
New System.Net.NetworkCredential("user name",
"password",
"domain name")
MsgBox("Square
of 2 = "& ws.Square(2))
Dts.TaskResult = Dts.Results.Success
End

Creating and consuming web service

Hello Everyone,
Please help me in creating a webservice which can be consumed in a button in Excel sheet i.e. I have to create a button in Excel sheet and on click of that button i have to consume a web service deployed in AS. Also I have to pass the data in Excel sheet to that web service.
PS: This is just a business logic no other view or UI is required here.
Thanks in advance.
Regards
Pranav

Hi Pranav
>2. I know I can download WSDL files from server using the test page. Downloaded zip file has these three wsdl files Config1_document.wsdl, Config1_TestVi_document.wsdl and main.wsdl. But which wsdl to use while consuming.
Actually all the .wsdl files are part of single WSDL document which describes your Web service. Starting/root point here is main.wsdl which references two other .wsdl. You can access any time the root WSDL part by URL like
"http://<host>:<port>/BcfRemoteCheck/Config1?wsdl&style=document&mode=standard".
Hope you know where to see the WSDL URL (in Webservice Navigator or in Single Service Administration where you downloaded the ZIP).
When you are consuming web-service you need all the parts. Usually when a Web-service is consumed the remote WSDL is used for generation of WS Client Proxy. But, the WSDL files can be also downloaded and used locally for generation of the WS Client Proxy.
Sometimes the WSDL is not necessary at all for WS consuming on run-time. In the case it's used only on design-time just to know WS names, ports, operations, etc, for writing the code of WS Client.

Hi Vijay,
Thanks for the Reply.
Please provide the JAR Files i need to add.
I had tried to consume the web service by using the java class in Java Project ie EJB.
After creating the Project i will import the WSDL file in that Project and create the Client Application.
The Request and Response java class is created by importing the WSDL file.
The Client Java Class is created to access the Request and Response objects.
After this Main class is created and I have run the application to execute the Client Java Class. During this time its shows some error.
