Sending paramters from Web dynpro to web services

Hi,
I need to send extra objects or paramters to my web service from web dynpro which are not part of user inputs. How can i achieve it? Iam new to web dynpro. pls help me with sample code.
Thanks a lot in advance

hello Sujesh,
in webdynpro we import a webservice model. it contains all the necessary input parameters and u can pass value through it. i think u cannot pass extra objects or parameter other than these input parameters.
can u make ur requirement much more clear.
regards,
Piyush.

How to send sms from pc to various mobile service in india

I am trying to send sms from my pc to various service provider(airtel, hutch, bsnl).But i am able to send only to airtel connection(using thier website : [email protected]). But i am unable to send to other service provider. Or is it required to have SMS centre(SMSC) for sending SMS And also how inditimes 8888 will work(automatic replay for SMS)
Anybody can help in this topic
Thanking you

do google search. there are a lot of free sms gateways available over the internet. they come with java apis too. generally speaking, an sms can be sent to a phone only thru its SMSC. however, some sms gateways need you to connect a mobile to your com port so that they can send sms thru that. (in that case the sms flow will be like this: yourcomputer --> your mobile --> your mobile's smsc --> receiving phone's smsc --> receiver phone) hope i have not confused you..

Web Dynpro Domino Web Service Consumer Problem

Dear All,
We are trying to consume a Web Service on Domino.
The web service is working Fine on webdynpro web service checker (EP perspective, Web Service Checker), but when tested with check and deploy, the Webservice return an error:
"Service call exception; nested exception is: com.sap.engine.lib.xml.parser.ParserException: The empty string is not acceptable for a value of an xmlns:* attribute.(:main:, row:1, col:0)"
It is a simple web service getting a string in input and returning a simple string (xsd string in both cases),
here are the soap messages used:
Input

this information came from the Webdynpro web service checker (or EP web service checker in Netweaver developer studio).
Any Idea will be welcome.

I initialize correctly the Web service and the field number (with new String()) in the component controller.
When I click on the Button divide on the web dynpro interface, I call the executerequest defined in the component controller where I execute the call.
But the response is always the same:

What can i do or check, or can I debug the soap generated or received by the portal?
Do you see something wrong?

Web Dynpro Import Web Service Model - not a valid NCName

Hi people,
We are having a problem while importing a WSDL as an Adaptive Web Service Model in Web Dynpro (CE 7.2 SP03).
The error is the following:
"Definition of qualified base /schema/element[5]/complexType/sequence/element[4] is not correct. The value of property is not a valid NCName."
We tried importing the same WSDL in other tools (XML Spy and SOAP UI). With these tools it could be read without errors and were able to successfully call the service.
The point is, why the import fails in Web Dynpro if the WSDL can be read in other tools ? Can we do something in WD to import the WSDL that is supposed to be "not correct" ?
Thanks in advance for your comments,
Daniel

Hi Pranav,
I was facing this issue sometime back and i figured out that the ABAP proxy namespace in my case had a '/' in it, because of which the internal name of the service had a '/' character too.
And this was unacceptable for the endpoint binding name in my case.
Since it is occuring for you in case of the service name (i figured it out from attribute definations/services@name), check if the proxy name have a special character like '/'.

Vivek

Web Dynpro access Application Services directly?

We're looking at implementing some processes using Guide Procedures, and I have a question about design 'style'.
I'm creating a data layer using Entity Services. The entity services will be utilized by the Application Services to create a business layer. How to do this is clear, and straightforward.
However, where I have a question is how the automatically generated Web Dynpro application (or any other Web Dynpro application, for that matter) can interact with Application Services. I've seen sample applications where the Web Dynpro application interacts with application services via mapping from the Web Dynpro interface layer through the GP Runtime - from my perspective, this looks like a good way to deal with a small amount of data being passed between the steps in the GP.
The primary Web Dynpro application will let the user interact with the data, massaging it until it's in a form where the next person needs to deal with it. I was thinking of having the Web Dynpro application interact with the Application Services layer directly to move data from the database to the web dynpro application, and back again. The only thing that would be passed between the steps in the GP would be the guid of the primary data structure. I would also expose a method of the Application Service as a CO which would take the guid and return the entire business object, so viewing screens could be constructed - as well, PDF's could be generated, and so on.
Is this considered bad form in a GP, specifically accessing Application Services directly, instead of through a step in the GP? I understand that what I want to do ties the Web Dynpro application directly to the Application Services layer, but my thinking is that the CO that encompasses the Web Dynpro should be 'atomic', in that all operations related to that specific step should be contained in a single CO. In other words, the action of creating the business object, fiddling with it, an then submitting it upstream should be contained in one CO.
Comments, suggestions?

Hi,
      In the Composite Application Framework scenario, you first create the Business Entities. These act as data holder. To fill the data within these entities the Application services are created. These application services are later exposed as a webservice and deployed.
               These webservices can contain different methods along with the CRUD operations depending on the Process Flow and Design implemented. We can import the webservices as a model in the WebDynPro Component. The UI elements of the Views can be binded to the Model. So when we execute the model methods the data gets entered into the Business objects.
               This WebDynPro component should be a callable object ( It requires some Dependencies to be added to the WebDynPro Component ). So that you can have Input/Output parameters and ResultStates. These parameters are useful if you have to pass some parameters from one view to other within the same component. So this WebDynPro Callable object includes the Application service calls and also the passing of data through the GP Input/Output Structures.
               These callable objects are then included within the Process.
This is how I think a Composite Application must be designed.

WEB DYNPRO AND WEB SERVICE MODEL: ejb remove doesn't work

Hi guru,
this is my scenario:
J2EE-7.00 SP14-> PORTAL ->7 sp14 ->WEB DYNPRO FOR JAVA ->Web Service Model -> WS Custom with MDM API JAVA
The my WS is a Stateless Session Bean and i have this code:
     public void ejbCreate() throws CreateException {
          loc.setMinimumSeverity(Severity.INFO);
          loc.addLog(new ConsoleLog());
          this.plug = (MdmPlug) new MdmPlug(true);
          try {
               this.loadProperties();
               this.plug.connect(
                    hostname,
                    repository,
                    language,
                    username,
                    password);
               loc.fatalT(msgLog+"[ ejbCreate ] START....");
          } catch (Exception e) {
               if (e.getMessage()!=null)this.error=e.getMessage();
               loc.fatalT(msgLog, this.error);
public void ejbRemove() {
          try {
               loc.fatalT(msgLog+"[ ejbRemove ] STOP....");
               this.plug.close();
               loc.fatalT(msgLog+"[ ejbRemove ] ...OK");
          } catch (ControlException e) {
               loc.fatalT(msgLog+"[ ejbRemove ] ...K O !!!!");
The my problem is:
When open the IE and open my WD the new EJB's instance is created (I see my log +"[ ejbCreate ] START....in LOG VIEWER).
But, when I do log-off or I close IE, I don't see "[ ejbRemove ] STOP...." in LOG.
Result:
I open the MDM connection but not close it.
Where is the problem?
In Web Dynpro?
In Web services?
I have to create another WS's type?

Hi Max,
You can't run an EJBControl from a simple java class using either @Control or programmatic instantiation.
The EJBControl implementation relies on Resource Context events so it "needs" a container context to run.
You can use the ControlTestCase to unit test an EJB via EJB Control. You will need to configure the JNDIContextEnv annotation to bind to the server where the EJB is deployed. Note that this only works with EJBs that have a remote interface and a global JNDI name.
The test case would look something like this (I've seen this example run as long as the JUnit classpath includes weblogic.jar)
public class SimpleClient extends ControlTestCase {
public void setUp() throws Exception { super.setUp(); }
public void tearDown() throws Exception { super.tearDown(); }
@Control
@EchoEjbControl.JNDIContextEnv(
contextFactory="weblogic.jndi.WLInitialContextFactory",
providerURL="t3://localhost:7001",
principal="weblogic",
credentials="weblogic"
public EchoEjbControl echoEjb;
public void testXXX() {} // ... test methods that reference echoEjb

Web dynpro and Web Services

Hi all,
I want to create a Web Service, that calls a BAPI or RFC similar to the "Webdynpro components".
Can someone tell me a way to create this Web Service?
Or have I to do this manually over a EJB?
Regards
Olli

Hi Olli,
it's possible to generate Web Services from RFMs. Please have a look at the following doc: http://help.sap.com/saphelp_nw04/helpdata/en/0d/2eac5a56d7e345853fe9c935954ff1/frameset.htm
Having done so and after WSDL generation and publishing (documentation how to do this is also available), it's possible to import the published WSDL source as a Web Dynpro Web Services model (via UDDI or URL).
Hope that helps.
Regards
Stefan

Web Dynpro and Web Service Error

Hi experts,
I followed the blog u201CDeveloping Web Services in J2EEu201D /people/lakshmi.prasad5/blog/2009/06/30/developing-web-services-in-j2ee-and-consuming-in-sap-netweaver-visual-composer-part1 and is very well explained and easy to follow. The author does two Methods and the final Web Service concatenates input fields. One Method concatenates two words and the second Method concatenates three words, the final result is the concatenation of the words in both cases. The Web Services is working fine I already tested and do it in a Visual Composer Project. Now, I want to Execute the Web Service in a Web Dynpro for Java WD4J Project. I did my application, my model (ConcatinationWSModel) and my View. I mapped the class that concatenates two words and is call u201CRequest_ConcatinationOfStringu201D. The problem comes with the Execution of the Web Service and is showing me the next exception:
u201Ccom.sap.tc.webdynpro.model.webservice.api.WDWSModelExecuteException: Exception on execution of web service with WSDL URL 'http://<host>:<port>/WebServiceconCat/Config1?wsdl ' with operation 'concatinationOfStrings' in interface 'WebServiceconCatVi_Document'u201D
My method DoInit (Set SAP & UK):
public void wdDoInit()
    //@@begin wdDoInit()
          ConcatinationWSModel model = new ConcatinationWSModel();
          Request_ConcatinationOfStrings input = new Request_ConcatinationOfStrings(model);
          wdContext.nodeRequest_ConcatinationOfStrings().bind(input);
          ConcatinationOfStrings input2 = new ConcatinationOfStrings(model);
          wdContext.nodeConcatinationOfStrings().bind(input2);
          input2.setFString("SAP");
          input2.setSString("UK");
          ConcatinationOfStringsResponse input3 = new ConcatinationOfStringsResponse(model);
    //@@end
My method onAction is:

    //@@begin onActionExecuteWS(ServerEvent)
     try {
          wdContext.currentRequest_ConcatinationOfStringsElement().modelObject().execute();
wdContext.nodeRequest_ConcatinationOfStrings().invalidate();
     catch (Exception ex)
                    // TODO: handle exception
                    //        If an exception is thrown, then the stack trace will be printed
          wdComponentAPI.getMessageManager().reportException("The error is: " + ex,true);
    //@@end
I believe that the error is in the way I am executing the Web Service but I am not sure. Any help will be appreciated.
Best Regards
David Corté

Hi Jesus,
Your answer was very helpful..... The problem was with my code. The way I was executing my web service was wrong..... There are two things we have to keep in mind while we invoke any web service.... The doinit method and the execution sentence.....
public void wdDoInit()
    //@@begin wdDoInit()
     model = new ModelWebServcie();
     Request_ConcatinationOfStrings input = new Request_ConcatinationOfStrings(model);
     ConcatinationOfStrings input2 = new ConcatinationOfStrings(model);
     input.setConcatinationOfStrings(input2);
     wdContext.nodeRequest_ConcatinationOfStrings().bind(input);
    //@@end
and the exection method:
public void ExecuteWebService( )
    //@@begin ExecuteWebService()
     try {
                    wdContext.currentRequest_ConcatinationOfStringsElement().modelObject().execute();
                    wdContext.nodeResponse().invalidate();
               catch (Exception ex)
                         // TODO: handle exception
                         //        If an exception is thrown, then the stack trace will be printed
               wdComponentAPI.getMessageManager().reportException("El error en ExecuteWS es: " + ex,true);
               wdComponentAPI.getMessageManager().reportSuccess("El Web Service fue ejecutado con exito");
    //@@end
Declare member variable for model instance:
//@@begin others
private ModelWebServcie model;
//@@end
Thank you for everything...

Web Dynpro automatically activate service after transport

Hi all!
Well - I've searched SDN. I've read notes.   I googled. I can't seem to find exactly what I want.    When a web dynpro component transports it automatically activates in the new system. However, the application creates an ICF entry.   That "service" does not automatically activate. I can go to SICF and activate, but I don't want to do that in all the systems. Nor do I have the authority in all systems.
Everything I've read on SDN seems to point to the fact that it can't be automatically activated. The notes that I've read seem to piont to the fact that it can be activated automatically with the correct Basis settings.
When the application is created it automatically creates a "service" in http:server//sap/bc/webdynpro/sap/application.   Maybe it should be in a custom namespace?
Anyway I'm stuck - any help you could provide would be great. I'm on ECC 6.0.
I've already read these notes that seem like they would help:
1088717
1124553
1043195
I've tried running RSICF_SERVICE_ACTIVATION.
I can activate the service manually.   It just isn't something that I'd like to do.
This may not be the correct forum, but as it relates directly to WDA, I thought I'd give it a try here.
Thank you!
Michelle
I've looked at these threads:
web dynpro service inactive after migration
Why Web Dynpro Application can not work in UAT ?

Hi Thomas,
I just want to add that a user who creates this variant, still needs authorization for Tcode SICF. But you're right, this could be done ones for a range of services.

How to send EDI from WCF adapter to WCF service

Hi,
1. I have created an orchestration which is published as WCF service.
2. I have created an orchestration which receives an XML from WCF client and process it.
3. I have created a WCF dynamic send port.
Problem: From this dynamic send port, I want to send EDI file to a WCF service that will receive this EDI file. How can I achieve this. Below are my concerns:
-> For creating this WCF service, I need to know the contract of Biztalk WCF adapter which sends EDI file.
Thanks ...

Hi,
How can we create WCF service to receive the EDI sent by the BTS. What contract should be used for receiving this EDI file in WCF service.
What changes have to be made in the orchestrations to send the EDI file to the WCF send Dynamic port. Below is the code i am using.
EDIOutboundPort(Microsoft.XLANGs.BaseTypes.Address)="URL Address";
EDIOutboundPort(Microsoft.XLANGs.BaseTypes.TransportType)="WCF-basicHttp";
Please correct me if i am wrong
Thanks
"How can we create WCF service to receive the EDI sent by the BTS. What contract should be used for receiving this EDI file in WCF service" - This is two different questions.
"How can we create WCF service to receive the EDI sent by the BTS" - Using BizTalk WCF Services Publishing Wizard, the wizard would ask for the "Create BizTalk receive locations in the following application " for creating
the receive location for the message published to the exposed WCF service. Through this receive port/location, the service would receive the message.
In this case, I am not sure why do you want to expose the Orchestration as WCF Service when you want to send message to this Orchestration/WCF service (which after converting from Orch) through another orchestration. You could either use call/start orchestration
to send message from one to another.
"What contract should be used for receiving this EDI file in WCF service" - may be this question is not correct. You have created a Orchestration which you exposed as WCF service. So while creating the Orch you know the type of message this Orchestration
is bound to, so use the same contract. Or as mentioned in my earlier reply, use "Consume WCF wizard" to consume the WCF service which would create the web message for you.

Integrate web dynpro into WEB UI

Hi,
I have a problem with integrating wd4a application into web ui.
When I set up url of the wd4a application (absolute url) as logical link, everything went ok in dev system.
But after transport to test system, application was not reachable, because absolute url linked to dev.
The second attemp was to set up the logical link to BSP application, which called absolute url to wd4a application using <bsp:call> statement in view. The problem is that this statement didnt work at all and it doesnt matter if there link to my application or to google.com.
do you have any idea how to solve this?
thanks
Juraj

Hi,
I know this method,
but problem is that I used absolute link in WEB UI customizing, tx CRMC_IC_LTX_URLS ... in case I could create my own link, everything is ok
my problem is that I dont know how to define link in this tx with relative url
or I can be solved in way that I somehow integrate web dynpro into BSP application and then set up URL in tx CRMC_IC_LTX_URLS for the BSP.
the only problem is I dont kobw how to do this
thanks
Juraj

Web Dynpro ABAP == Web Dynpro Java

Hi Gurus,
I've written a Web Dynpro Abap Application to maintain CRM Opportunities, working with Transaction-ID and everything (read&write) works fine.
Now, I'd like to write the same Application in Web Dynpro Java.
I'm quite new in WDJ and thus would like to have some good Howtos & Guides (using the NWDI, CMS, CBS & DTR on a remote J2EE Engine) - e.g. how do I get information out of FMs I used in Abap, like CRM_ORDERADM_H_READ_OB when writing code in Java?
Thanks in Advice,
Farid

Question about meta-data of Web Dynpro ABAP / Web Dynpro Java

Hello together,
everywhere I can read, that Web Dynpro meta-data is platform independent.
I´ve read into a book, that the meta-data of Web Dynpro Java is saved as XML and
that Web-Dynpro Java Runtime generates runnable classes and sourcecode out of this...
- What about Web-Dynpro ABAP? Is Meta-code in ABAP is saved in XML too?
- just for theory: is ist possible to take the meta-data of a Web-Dynpro ABAP component and
generate a Web-Dynpro Java Component out of this?
I tried to find it out but i failed... In table WDR_RR_LOAD (is this the right one?) I found only the
field data. But this is a RAWSTRING and I don´t know how to make I "readable".
I must know this for my thesis for my studies, not for work.
Thank you very much !!!!
Greetings,
Oliver

Me again,
I am not sure if I understood it right...
The meta-data which describes the visual part of a view is saved as XML and
would be rendered i.e. in the webbrowser... Right?
What about the meta-data of the Web Dynpro application?
Is this meta-code into an other structure or XML too?
Thank you very much.
Many Greetings,
Oliver
