Calling another web dynpro in a web dynpro programm

Hi experts,
I am new to web dynpro. And I am working on several web dynpro applications. I just want to know how to call another web dynpro within a web dynpro application. Don't use popups, I'd like the web dynpro work together in the same window just like a wizard.
Thanks a lot.

Hi Guo,
Yes, you can achieve it by Component Usage. You can embed other component's Interface views into your own Windows. Check out the component Usage information in help.sap.com to get a clear idea of it.

Web Dynpro ABAP calling another ABAP program

I have a question and just want to know if it's possible or not.
Is it possible to write a Web Dynpro ABAP program that calls another ABAP program which happens to be an ALV report?
Rather than re-write the ABAP ALV report, I was wondering if it's possible to call the ABAP ALV report within a Web Dynpro ABAP program and display the results within the Web Dynpro program.
If it's not possible, then I assume it would be better to re-write the code from the ABAP ALV report in the Web Dynpro ABAP program.
Thanks
John

The ALV report in your classic program is coded to be displayed in the GUI only.
Your best bet would be to create a Function Module or Method that will return the data to be used in your ALV. Simply call the Function/Method from your Web Dynpro and then bind the table to the DATA context node of the ALV INTERFACE CONTROLLER.

Problem in calling XI generated Web Service via Java Web Dynpro

Hi experts,
I have problems with calling a web service, which was created by XI. I have already tested the web service with Altova XMLSpy. The Web Service works fine.
But when embedding this web service into Java Web dynpro application no message flow is given. I have two views one Selection View and one Result View which should show the answer sent by RFC-Call.
My Settings in NWDS:
During configuration of web dynpro I have choosen 'Import adaptive Web Service Model' --> Select wsdl file via local file system --> 'no logical destinations - use WSDL URL for metadata retrieval and web service execution'.
The model is also not shown in diagram view although I have added into the diagram.
The web service was created on XI 7.0.
Should I do any other settings e.g. in Visual Administrator, Web Dynpro Content Administrator?
So can anybody help me.
Thanks a lot.
Regards,
Mario

Hi Aviad,
thanks for your fast reply.
But in Web Service Navigator my Web Service is not shown, because I used the SOAP Adapter.
My Web Service link:
http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=:SRV_GBD_WS_GET_DEB_DETAIL:CC_GBD_WEBSERVICE_SENDER&version=3.0&Sender.Service=&Interface=%5E*
During executing Web Dynpro I got following errors:
1. 'The system cannot find the path specified'.
2. com.sap.tc.webdynpro.model.webservice.exception.WSModelRuntimeException: Exception on creation of service metadata for WSDL URL

Call a user defined method in web dynpro from interactive forms

thanks.

Well, you can use F4 help, of course, check here: http://help.sap.com/saphelp_nw70ehp1/helpdata/en/48/a1900622ec062be10000000a42189d/frameset.htm
You need to select the value first and then use the submit button, which is mapped to the WD action submit (you have to set this up in WD designer!!). To use the submit button for more actions, you need to use something like a hidden field, where the value is set according to the action you want to do with your submit button. The submit sends this value back to WD, where you can switch the program code according to the value.

Calling an ABAP web service from a web dynpro

Hello,
I based my application on the: "Creating an E-Mail Client Using Web Dynpro's Adaptive Web Service Model" tutorial but when invoking the web service I get this type of error:
Exception on execution of web service with WSDL URL 'http://mySAPBackendServer:1080/sap/bc/soap/wsdl11?services=Z_MY_WEB_SERVICE&sap-client=XXX&sap-user=XXXX&sap-password=XXXX' with operation 'Z_MY_WEB_SERVICE' in interface '{urn:sap-com:document:sap:rfc:functions}Z_MY_WEB_SERVICEPortType'
Is this because I used Adaptive Web Service Model instead of Adaptive RFC Model? Or is it due to something else?
thanks a lot,
Tanguy Mezzano

The function module is remote-enabled, it is exposed thus as a web-service, I can retrieve it with webservicebrowser application.
Shantoo:
I have tried to create a Web Dynpro with the RFC method to create the model but when I run and deploy I get a deployement error with:
Result
=> deployment aborted : file:/C:/DOCUME~1/..Webservice.ear
Aborted: development component 'WebDynpro_Webservice'/'local'/'LOKAL'/...'0':
Caught exception during application deployment from SAP J2EE Engine's deploy service:

Web Service Consumption in Web Dynpro Java

Hi,
I'm using NetWeaver 2004s for Java. I have generated a Web Service out of a BAPI. I use that Web Service in a Web Dynpro Java Application as Model. Model generation works fine. But when I call the Web Service during execution of the corresponding Web Dynpro Application, I get the following Exception:
"java.rmi.RemoteException: Service call exception; nested exception is: java.lang.Exception: Call to returned http code 500 with unacceptable content type (text/html; charset=iso-8859-1). <HTML> <HEAD> <TITLE>Unknown Host</TITLE> </HEAD> <BODY BGCOLOR="white" FGCOLOR="black"> <H1>Unknown Host</H1> <HR> Description: Unable to locate the server named "us0308.wdf.sap.corp" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again. <HR> </BODY>"
Testing the Web Service via transaction WSADMIN works fine. Can anybody give me an advise how to solve that problem?
Thanks in advance!
Regards,
Frank

Had Exactly same problem with authorization issues on the server hosting the webservices.
Create a CPIC user Id on the server hosting the webservice. The user id should have authorization to execute the webservice.
Create a webservice destination in VA for the said webservice using the user id
1. Log on to the J2EE Engine as an administrator using the Visual Administrator.
2. Expand -> Server ->Services.
3. Select the Destinations service.
4. Under Destinations, select HTTP and choose New
You need to create two destinations one for matadata and another for execution data.
Use the destinations while creating the WS model in NWDS.
if you have issues importing the model using the URL, you can create the model using the WSDL and use the WS Destinations to execute it.
I am following the same approach after i had faced similar issues with webservices on PI7.1 and Portal 7.0
About the option to use _setusername, _set...., not all webservices come with the _set methods.
and moreover if you do that, it would be more of hardcoding in the code, which should be avoided.

Nitin

Created in Web dynpro Java or Web dynpro ABAP

hi all,
I have a web application running. Its UI is created either in web dynpro java or web dynpro ABAP. Is there any way by which we can find out that in which form of UI technology is it created; in web dynrpo java or web dynpro ABAP ?

Hi,
I am really not sure if this is recommended..
Try some negative testing on the application. If the application crashes, the trace of the error occured will tell you what kind of development has been adopted for the Web Dynpro application.
Another hint can be the port number in the Application URL. If it is not 50xxx, and is somewht like 8xxx, it is surely Web Dynpro for ABAP.

Alka.

Can I use Web Dynpro to provide Web Services

I know I can use Adative web services model to consume existing web services. But I have not seen any example to use Web Dynpro as the web service provider. Can this be done? If yes, how?
Thanks.

Hi,
WebDynPro Java/ABAP are primarily User Interface technologies. Webservices are faceless (without UI ) components that provide certain functionality. Using UI technologies like WebDynPro Java/ABAP etc, we can build a face( UI ) to the webservices.
DnyPro itself means a screen & WebDynPro is for building web based applciations.
Hope this resolves your question.
Well, if you still want to use it as provider & if you have an existing web-service, the way to do it is, Right click on your WebDynPro ABAP component & select CREATE->Service Call. Build a Custom Controller or use the Component Controller to get the service using service type = Webservice proxy for your webservice. You can use this Component as a Used component in any other webdynpro components & use this to access webservices.
Thanks,
Phani

How to consume the Abap web service in Java web-dynpro

Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
Vikas

Hi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
 I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
 procedure"
 Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
 signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

How can I create a web Service from my Web Dynpro Application ?

Hi,
Kindly let me know How I could create a "Web Service" with my Web Dynpro DC project.
Awaiting your responses.
Regards,
Mahesh

Hi Mahesh,
You can use the web services by creating the Model in web Dynpro
And if you want to publish your own web service then you have to create a EJB module and publish as a web service.
Thanks
