Hi Experts,
My requirement is I have to call an URL by exporting an XML file to that URL I have to import an XML file again i .e nothing but I have to send request file in the form of XML and need to get response in the form of XML file from the URL .This total execution should be finished by clicking a button in webdynpro ABAP.

Hello Satya,
You may try to find the sample code as follows:
1. Goto Transaction se80
2. Select "package" --> enter "SWDP"
3. goto "embedded packages" --> "SWDP_DEMO" --> Web Dynpro
Here, you will get demo applications. Find the most appropriate demo application and try to customize the code according to your requirement.

How to use Webservice in Webdynpro ABAP?

I tried searching option for importing WSDL file in WebDynpro ABAP. But I am unable to upload it in my component. In service call wizard I can see only one option i.e. to import Function module.
We cant use Webservice in ABAP webdynpro?
Thanks
Nitesh Shelar

Thanks Rich for quick answer.
But my problem is, I have a stand alone WAS without any RFC Function modules and dictionary structures, of backend R/3, on WAS which I wanted to map in my component.
I strongly believe that in case of stand alone WAS I need to have at least backend dictionary structures to begin with my design. I cant use wizard, as I dont have function modules on this system. I have to code for that manually..
So that is why, I was looking for Webservice option..
Thanks,
Nitesh Shelar.

Problem in calling Webservice from Webdynpro ABAP

I want to call a BAPI FM which is available in SAP ECC server when user is clicking on a button in a web dynpro application which is available in SAP Portal server.
For example,
Portal server name is DVP-EPP &
ECC server name is DVP-ECC
I have the done the following steps to achieve it,
In Server DVP ECC:
1) Created Web service from the standard BAPI FM (SE37-->Utilities-->More Utilities-->Create WebService --> From the the Func.Module)
2) Downloaded the WebService as WSDL file from SOAMANAGER
3) Tested the Web service through SE80, it is correctly calling the BAPI & creating necessary data.
In Server DVP EPP:
4) Created a Proxy class as follows,
a) SE80 --> Package --> Create --> Enterprise service
b) Selected Object type "Service Consumer"
c) Selected Service Consumer "Local File"
d) Browsed and selected WSDL file downloaded from DVP ECC
e) Selected the Package, Prefix, Request, Completed the process & Activated it.
5) Configured the Logical port as follows,
a) Selected my Proxy class through F4
b) Wrote a name for Logical port, Selected 'Default port' checkbox and selected 'Create'
c) In the next screen, in 'Call parameters' tab, selected the 'URL' radio button & mentioned the URL of the WSDL-Document created in DVP-ECC system
d) Saved the data & activated it
5) Now, tested the service through (SE80-->Package-->Enterprise Services-->Client Proxy) option.
6) When I test it, system prompts a dialog box for User-Name & Password (as available in DVP-ECC system).
After the details are given, system throws the Information message as "SOAP:14 Unexpected element -el=definitions ns=http://schemas.xmlsoap.org/wsdl/" - Exception of class CX_AI_SYSTEM_FAULT
No record is created in DVP-ECC through the WebService BAPI.
Please tell me whether the steps that I followed are correct as per my requirement and a solution for the above interruption.
Thanks in advance

Good day guys,
Somehow I managed to resolve the above error.
Now in DVP-EPP system, I am able to Test the Web service Client Proxy (through SE80) and a record is successfully created in destination system (DVP-ECC).
Now, in Webdynpro I am unable to call this webservice proxy class.
System throws the error,
Error (id=SoapFaultCode:5): Web service processing error; more details in the
web service error log on provider side (UTC timestamp 20141006045544;
Transaction ID 9A144DE49C12F1B5A6B9E41F137BE3CC)
I just created a sample WDA application and on click of a button I am calling the Webservice Proxy class as follows,
Method on_submit_click().
TRY.
      CREATE OBJECT wd_assist
        EXPORTING
          logical_port_name = 'ZLOG_PORT'. "Logic port creatd for Proxy class (in SOAMANAGER)
      CALL METHOD wd_assist->bus1240create     "Method available in generated Proxy Class
        EXPORTING
          input = ls_inp
        IMPORTING
          output = ls_outp.
    CATCH cx_ai_system_fault.
ENDTRY.
ENDMETHOD.
Do I have to do any thing additionally in order to call the WebService in WDA?? Because, in the same system, if I test it in SE80, record is perfectly created in destination server.
Also please suggest if I have to do any other configuration changes related to this.
Keenly awaiting your reply.
Have a nice day .
Thank you.

Hey,
You can call a GP from WD ABAP through by implementing a service call from a method that is embedded in your WD. You can refer this link for the same.
http://help.sap.com/saphelp_nwce10/helpdata/en/44/58f9cc0d95311ce10000000a155369/frameset.htm
But you should note here that Data exchange between ABAP WD and GP is not two way but its only one way.

How to call a webService from WebDynPro ABAP ?

We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
How exactly do we call a WebService from a WebDynPro-ABAP application?
What are the main steps involved ?

Hi Phani,
You will need to create a service call as follows.
Right click on your WD component name and select Create->Service Call
The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.

How to use messages in WebDynpro-ABAP

Hi,
How to use messages in WebDynpro-ABAP.
Does it has any class to manage messages like IWDMessageManager or we can just use standard SAP Message types.. like E,W,X,I,S..
I hope it have a message container to display messages.
Thank U for Ur time.
Cheers,
Sam

Hi Sam,
U can hard code the message or u can use the Assistance class's text elements to store the messages.
1) Code to display hard coded message:
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = "Enter the correct Connection ID"
element = elem_flightinfo
attribute_name = 'CONNID'.
2) Code to display message from text element of assistance class:
lv_text = wd_assist->if_wd_component_assistance~get_text( key = '002' ).
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = lv_text
element = elem_flightinfo
attribute_name = 'CONNID'.
Where Message "Enter the Correct Connection ID" is stored in Text Element with key '002'
Hope this helps,

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:
