Hi,
I want to develop a webservice in webdynpro for consuming BAPI(BAPI_MATERIAL_AVAILABILITY).
Can someone provide me the related document to reach this requirement?
Thanks,

Consuming webservice in a webdynpro component

Hi Experts,
I have a third party free webservice as WSDL link.My requirement is to make use of that webservice in my webdynpro component.
Can any body give me a step by step approach to consume that webservice in my webdynpro Component.
If possible, Provide me some good material for consuming webservice in a webdynpro component.
Awaiting for a useful reply.
Thanks,

It is possible to create webservice in ABAP as well as in Webdynpro.

In Web Dynpro ABAP there is nothing special about calling a web service. Unlike WD Java, there are not dedicated model object types in WD ABAP. WD ABAP simply has the ability to interact with other ABAP development object types. You can call function modules, ABAP classes, even modules in old dynpro apps.
So calling the webservice from ABAP therefore is just the process of generating the ABAP Proxy Class. This is the same process regardless of if you want to use this proxy class from WDA or any other type of ABAP development object. You can then call the proxy class from WDA just like any other type of ABAP class. There is a service wizard option in later support package levels that includes an option for ABAP Proxy classes - although it doesn't generate the proxy class it just generates the code and context for the call to an already existing proxy class. The service wizards in WD ABAP are not required however. They are just shortcut code generators and often can't even generate a complete context for a complex web service proxy - so expect to do some manual adjustment after running the wizard.

Webservice Exception from Webdynpro

Hi,
We are on 7.1 SP04 Patch 1. We have created a webservice with http and None Authentication and deployed on EP 7.0 server. We have set a constant User Name and Password in Visual Admin.
We are able to execute this webservice successfully from Webservice navigator.
We have developed a Webdynpro appln with this webservice. We are getting an exception when the webservice is getting executed from Webdynpro appln.
"Exception on execution of webservice with WSDL url '<wsdl url>' with operation 'webservice name' in interface"
We checked in the trace file and got the following message
com.sap.mdm.logging.MdmLogger warning
WARNING: PingServerCommand failed
Have any one faced this issue?
Thanks,
Arun prabhu

Hi Walter,
The webservices are developed using MDM Webservice generator. The webdnpro application has to access MDM Data using MDM Webservices / MDM Java APIs.
This was working fine with MDM 7.1 SP03. Now we have upgraded to MDM 7.1 SP04.
When I try to access MDM Data from webdynpro using MDM Java API commands, I am getting an exception at AuthenticateUserSession Command. While access using MDM Webservices, I am getting an webservice exception and an entry in trace file.
Thanks,

Consuming MII WebService in Java WebDynpro

Hello,
We are facing a strange situation...
We define a transaction in MII to be consumed as WebService in Java WebDynpro. This transaction is a simple query on a DB returning 4 fields :
Shift code : SHIFT
Shift description : DESCRIPTION
Start time : START_TIME
End time : END_TIME
It works fine, we use the import adaptative web service wizzard in netweaver developper studio to use this WS...
But if we to an update on the webservice, changing a field name for example (SHIFT -> SHIFTCODE), we start to have trouble...
We got then the very helpful error message :
Exception on execution of web service with WSDL URL '<sever>/WebServices/GetShift' with operation 'Xacute' in interface 'XacuteWSSoap'
If I display the model info using wdContext.currentRequest_XacuteElement().modelObject().associatedModelClassInfo().getModelInfo().toString()
I got the following (extract) :
<ModelClassPropertyInfo name="SHIFT" dataType="com.sap.tc.webdynpro.model.webservice.types.string(java.lang.String)" readOnly="false" qName="SHIFT" required="true" backendType="null"/>
As you can see, the model definition is NOT updated and we still have SHIFT as name instead of SHIFTCODE...
If someboby has an idea, it will save us our life ;o)
Thank you
PS:it the same behaviour if we add a field...

Oliver -
Did you try to reimport the WS model ..? If yes and still doesn't work...Try to delete the old proxy in webdynpro ( adoptive ws) and import again.
To avoid code changes,you can give same old name while fresh import.
Adoptive WS in webdynpro is not really like Adoptive RFC .It has some limitations.
Thanks

How to consume a ABAP webservice in a webdynpro app?

Hi,
I have a BAPI in ABAP that is exposed as a webservice. I want to use this to build a webdynpro app so that i can consume this webservice. This BAPI returns the Employee data. As soon as the person logs into the portal i am going to pass his login id to this BAPI so that it retrieves the Employee data for that user id. But i need to know the procedure of consuming this webservice in a webdynpro app. Any pointers in this regard will be greatly appreciated.
Thanks,
Arun E V

Hi Arun,
Consumption of a web service is univesal I guess so it wont matter if it is an ABAP webservice. For consumtion of webservice in Web Dynpro you can go through the following tutorials

Problem with calling Webservice from Java Webdynpro

Hi,
I have a scenario where I need to call a Webservice through my Webdynpro application. I need to pass few parameters(of type string) and the Webservice is suppose to retrun a few records based on the input values.
When I run the webservice directly using the browser, the output is in XML format.
When I create a model for the webservice in webdynpro, the return value is a Node element of type java.lang.Object. From webdynpro, I am successfully able to make a call to the Webservice (as there is no exception with model execute command), but the return value is always null. I am not sure if the webservice is not returning any data or if I am not reading the correct context element. There is no documentation available for the webservice either.
Can anyone tell me what is that I am missing. Is it not possible for Webdynpro to call a webservice which can return only XML data?
Any help on this issue would be greatly appreciated.
Thanks,
Sudheer

Consuming WebServices in ABAP WebDynPro via webservice proxy code

Hi,
My requirement is to consume a webservice using WSDL(basic authentication) in WebDynPro ABAP. then based on the SOAP response I need to show a pop up message whether the response valid or not.?
I first tested the webservice by creating LPCONFIG Logical Port and generated WebService Proxy class.
It got response correctly with basic authentication enabled each time I send a request.
Secondly I generated webservice proxy code using service calls on creating webdynpro test application with some UI elements. Service call created Nodes,attributes and method correctly.
it's giving me error when it tries to invoke webservice method through generated code.
Question is that How do we code authentication to the webservice method via WebDynPro ABAP code.
I appreciate anyone who worked on this area and taken basic authentication via coding. or worked successfully through coding.
Thanks

XI Webservice Exception within Webdynpro component

Hi All,
I have created a model for an XI webservice within the webdynpro project and created 2 view one for search and the other for search results and have accordingly associated the context variables of these views to the import and response parameters of the web service.
Now when I execute the method associated with this service I receive a service exception as enclosed below :
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized
Can someone please tell me if there any settings to be done on the client or server settings.
Thanks in advance.

Consume a webservice developed in other than coldfusion in WS-Security mode

1. What are the prerequisites (any software installation, configuration) to be considered ?
Requirement : To consume a Webservice developed in other than coldfusion in WS-Secuirty mode .
Environment used : Windows 2003, IIS 6, Coldfusion 8, SQl server 2005
2. While trying to consume a public webservice through coldfusion , We received unable to read WSDL file and Unknown host exception error.Can you please advise. why we are receiving this error and solution ?

Thanks Dan Bracuk, for your reply.
What I could understand from Sivakarthikeyan post is that
Point 1)
It is mentioned that they are going to consume external webservices for which he would like to know whether any software/configuration is required to implement WS-Security (In IIS or coldfusion administrator)?
Point 2)
It could be a correct URL that he is using, from his description (2nd step) he gets a error message as "Unable to read WSDL file". If it of incorrect URL then he would have received file not found or other error message.
Can you please or anyone clarify?
Thanks,
Satheesh

(261718088) Q ADVC-4 Can Timer Control/Polling be used to interact with webservices developed outside of WLS?

Q<ADVC-4> Can Timer Control/Polling be used to interact with webservices developed
outside of WLS?
A<ADVC-4> Absolutely, Timer mechanisms are the appropriate way to make your web
service a client to another web service and are very useful to provide polling
mechanisms. Look at slides ADVC 9-11 to see more.

Webservice to a webdynpro

Hi,
Is there relation between webservice and webdynpro in ABAP..I mean how can we use these two together for achieving a user interface program...?????
I have very little knowledge in Web Service....!!! Excuse if this makes no sense...
Thanks,
ABAPer 007

Hi,
No you are getting a bit confused. No problems. I will get it cleared for you.
ABAPer 007 wrote:
I would like to tell my understanding.. So webservice is an architecture to develop UI technology and Web Dynpro a tool which utilizes this architecture to effectively explore UI technology....( Correct me if i am wrong ? )
Yogesh Answers:
Webservice is not an architecture to develop UI technology. Webservice is an architecture to utilize enterprise level logic. This logic either preexists in the form of SAP ABAP code (in SAP systems). For example creation of a Inquiry (SAP standard T-Code). Suppose i want to do it from my Webdynpro UI. So i ll utilize this standard enterprise code from a webservice.
ABAPer 007 wrote:
I developed one Web Dynpro program which takes some input and provides output based on it in another VIEW. Hence whether i can say I developed a Webservice ?
Yogesh answers:
No you did not develop a webservice. You only developed a platform that will ultimately consume a webservice.
ABAPer 007 wrote:
i developed a Webservice using ABAP transaction SE80 and attached a Function Group to it....But interesting thing is !!! how i should proceed further to test or consume it !!!!!!
Yogesh answers:
Yes its correct that you made a webservice out of a function group. To test it you can use the nwa.
http://<server>:<port>/nwa --> Web services navigator.
You require an appropriate wsdl link to the webservice.
This wsdl link will be available from the webservice definition in the workbench. Open the webservice and you will have a wsdl button/tab at the top of the screen.
