CE 7.1 - How to call CAF services from Web Dynpro

Hi,
whats the suggested way to call caf services from web dynpro?
Of course I can use the Web Service model. But can I call caf directly?
I read something about caf web dynpro model, but I cannot find it in nwds 7.1. On some older tutorial it was in context menu of caf project, but it seems to be removed.
best regards
tom

Hi ,
The standard way is to use the web service model.
You have to expose the the services as web service and then you can use the wsdl url in the Adaptive web service model option.
The above option will be available when you click the Model in the webdynpro application and the click create new model.
Hope it helps you.

Error while calling a web service in web dynpro through XI

Hello,
I was following a blog for Invoking Webservices using SAP XI
/people/siva.maranani/blog/2005/09/03/invoke-webservices-using-sapxi
I have done all the steps specified but when I import the wsdl file in web dynpro application and deploy the project I get the following error:
<b>"Exception on execution of web service with WSDL URL 'bankws_OUT_MI.wsdl' with operation 'bankws_OUT_MI' in interface 'bankws_OUT_MI'"</b>
where:
bankws_OUT_MI -
is the message interface name.
I have defined a web service in the integration reopsitory as follows:
<b>http://PEP:50000/XISOAPAdapter/MessageServlet?channel=:bankws:s_comm</b>
where
bankws --- service name
s_comm -
sender communication channel
selected 'bankws_OUT_MI' message interface from the given choices
'bankws_IN_MI' or 'bankws_OUT_MI'.
interface name: bankws_OUT_MI -
mesage interface name
Can anyone guide me how to proceed further. Also if possible can anyone send me some helpful documentation regarding how to call a web service in web dynpro through XI.
Thanks in advance.

hello everyone,
I made the whole scenario again and it is running succusfully in Xml spy. Now when i call the webservice in web dynpro... I get the following error:

Does anybody have an idea what mistake i am doing.

What is best practice for calling XI Services with Web Dynpro-Java?

We are trying to expose XI services to Web Dynpro via "Web Services". Our XI developers have successfully generated the WSDL file(s) for their XI services and handed off to the Web Dynpro developers.
The Java developers put the WSDL file to their local PC's and import as "Adaptive Web Services" data models. When the application is constructed and deployed to our development box, the application abends because the J2EE server on that box cannot locate the WSDL file at runtime (it was on the developers box at, say, "C:\temp\" and that directory does not exist on the dev server).
Since XI does not have a way of directly associating the generated WSDL file to the XI service, where is the best place to put the WSDL so it is readable at design time and at run time? Also, how do we reconcile that we'll have 3 WSDL files for each service (one for Dev, one for QA and one for Prod) and how is the model in Web Dynpro configured so it gets the right ome?
Does anyone have any good guide on how to do this? Have found plenty of "how to consume a Web Service in Web Dynpro" docs on SDN, but these XI services are not really traditional Web Services so the instructions break down when it comes time to deploy.

HI Bob,
As sometimes when you create a model using a local wsdl file then instead of refering to URL mentioned in wsdl file it refers to say, "C:\temp" folder from where you picked up that file. you can check target address of logical port. Due to this when you deploy application on server it try to search it in "c:\temp" path instead of it path specified at soap:address location in wsdl file.
Best way is re-import your Adaptive Web Services model using the URL specified in wsdl file as soap:address location.
like http://<IP>:<PORT>/XISOAPAdapter/MessageServlet?channel<xirequest>
or you can ask you XI developer to give url for webservice and username password of server

Unable to consume secured Web service from a Dynpro application

Hello,
I have followed <a href="http://help.sap.com/saphelp_nw04/helpdata/en/c3/bac36a469e4c75aba646077e71516d/frameset.htm">this tutorial</a>
in order to protect and consume a secured Web service from a Dynpro application using SAP logon ticket.
The problem is that after implementing everything needed I receive 401 Unauthorized when I am trying to consume it from the web dynpro side.
If I manually transfer the request the credentials, before the execute i.e:
modObj._setUser
modObj._setPassword
modObj.execute();
I am able to call it, meaning the dynpro application doesn't transfer these credentials to the Webservice even though it's authentication property is set to true.
Any idea how to solve it?

Try below steps
Add jars
o security.class
o tc/sec/destinations/interface
Setting WebDynpro project property
o Project>Properties>Web Dynpro References-->Interface references
 Name=tcsecdestinations~interface
o Project>Properties>Web Dynpro References-->Service reference

Dynamically Set httpdestination and Call web service
final InitialContext ctx = new InitialContext();
final DestinationService dstService = (DestinationService)ctx.lookup(DestinationService.JNDI_KEY);
if (dstService== null)
throw new NamingException ("Destination service not available");
final Destination destination = dstService.getDestination("HTTP"," DestinationName");

Consuming External Web Services in Web Dynpro Java

Hi All,
I an trying to consume external web service in Web dynpro java using Adaptive Web Service Model.
But getting below mentioned error while executing the web service
Exception on execution of web service with WSDL URL 'D:\Web Service Project\CurrencyConvertor.asmx.xml' with operation 'ConversionRate' in interface 'CurrencyConvertorSoap'
Steps i followed are as below:
1. Created Adaptive Web Service Model for this i select WSDL source as "Local File System or URL"
In next step i select No logical destination radio button and click on next
In next step, browse the WSDL file and successfully import the WSDL file.
2. After successfully importing the WSDL file i wrote below code in Init method:
WebModel modelweb = new WebModel();
Request_ConversionRate reqConversion = new Request_ConversionRate(modelweb);
ConversionRate conversion= new ConversionRate(modelweb);
reqConversion.setConversionRate(conversion);
wdContext.nodeRequest_ConversionRate().bind(reqConversion);
3.After that execute the model - code is given below :
    IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
      wdContext.currentRequest_ConversionRateElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeConversionRateResponse().invalidate();
    catch(Exception e)
      manager.reportException(e.getMessage(), false);
Please let me know how to resolve this.
Thanks

Hi,
You need to use destinations for metadata and modeldata.
Configure those destination in Visula admin.
you can refer to following link.

Consume Web Service in Web Dynpro

Hi Experts,
I´m currently trying to learn web dynpro development.
Scenario: I have one component which embed two views. One view is for enter customer number and in the other view I will see the name of the customer. The name of this customer is provided in a sap erp2005. I have develop a function modul and wich gave me the appropriate data(customer name). Then I create a web service base on this function module.
When I test this web serviec in WSNavigator, I get the customer name, so the web service is working well.
My Problem is: I can´t invoke this Web Service in Web Dynpro. My steps to invoke web service were: create a model with the web service wsdl and then I add this model in the component (in "Used Models").
I have create a application and assign it to the component. When I "Deploy new archive and Run" the application I be come the error: "Configuration not found for application: demo.sap.com/test_wd3,serviceRefId:7fecf23b-0895-48f3-9902-0e7015a705c3. Please check the configuration details from the NWA. You may have not assigned the Service Group to a Provider System, or the generation of the configuration has failed."
What do I have to consider or to set up?
It is right to assign the input field to the context parameter?
PS: I have followed the steps in this tutorial, but I don´t use XI or PI

Hi,
I have the following message error:
Exception on execution of web service with WSDL URL
'http://j2eeserver:port/xxxx/Config1?wsdl'
with operation 'RequestNode' in interface

When i debugged it, I found the following error:
Cannot find the required parameter [unTipoProducto] in request message content.
What is wrong?, I pasted the code of my method, that call to web service in the component controller.
public void Alta_Entrega( )
    //@@begin Alta_Entrega()
     String tipoProducto = wdContext.currentAlta_EntregaElement().getUnTipoProducto();
     Request_Alta_Entrega entregaMO = wdContext.currentRequest_Alta_EntregaElement().modelObject();
     if (!wdContext.currentAlta_EntregaElement().getUnTipoProducto().equalsIgnoreCase("")){

          if (logger.beDebug()) {

          try{
               entregaMO.setInvokerProperty(Stub.USERNAME_PROPERTY,"xxx");
               entregaMO.setInvokerProperty(Stub.PASSWORD_PROPERTY,"xxx");
               entregaMO.execute();
               wdContext.nodeResponse().invalidate();
               wdContext.nodeAlta_Entrega().invalidate();
          }catch (Exception e){
               manager.reportException(e.getMessage(),false);
          logger.debugT(entregaMO.wdGetRequestLog()); //request log (HTTP header + SOAP request)
          logger.debugT(entregaMO.wdGetResponseLog()); //response log (HTTP header + SOAP response)
          logger.debugT(entregaMO.associatedModelClassInfo().getModelInfo().toString()); //model metadata in XML format
          logger.debugT(entregaMO.toString()); //model object tree in XML format (= model context node content)
I hope you can understand me, because my english is very bad!!.
Thank you.

Consume XI web service in web dynpro application

HI All,
I have scenario access web service in web dynpro java, which is created by XI ..Now I have WSDL file. Using that WSDL file I have imported web service model(Adaptive web service method) in my web dynpro java.
By following the PDF document = https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b2bc0932-0d01-0010-6d8e-cff1b2f22bc7
I have created a Model as mentioned in the PDF.
Once model is created I have done the mapping from model to component controller, after that I need to execute the Web service model .For the execution I need to write a code in component controller :-
model class name = XIModel
XIModel obj = new XIModel();
Once I am done with the above coding , and when I try to run the application I get the following error :-
com.sap.engine.services.webservices.espbase.discovery.BaseIOException: Invalid Response Code 200 while accessing URL:http://atind037:50000/WSDL/GetPOPDF.wsdl. Response Message: OK. Content Type: content/unknown
Could you please help me with this at the earliest , as it is a urgent issue.
Regards,
Boopathi M.

Hi boopathi,
It seems your wsdl url is not correct. Put the http://atind037:50000/WSDL/GetPOPDF.wsdl
in your browser and check whether you are getting the WSDLDefinitions in xml format or not ?
In wsdl url put ? instead of .
URL : http://atind037:50000/WSDL/GetPOPDF?wsdl

Calling portal service from web service

Hello,
I'm trying to call portal service from web service. Is this possible? I'm getting an error.
For example, code:
IJCOClientService clientService = (IJCOClientService) PortalRuntime.getRuntimeResources().getService(IJCOClientService.KEY);
.. is generating exception:
java.lang.LinkageError: Class com/sapportals/portal/prt/runtime/IPortalRuntimeResources violates loader constraints
Do anybody knows what's wrong?
Best regards,

Hi Josef,
Is the IJCOClientService located on the producer side or on the consumer side?

Help - cannot access web service outside web proxy

I'm trying to access a public web service - and web proxy stops me from doing it.
Here is my code:
package test;
import java.rmi.RemoteException;
import javax.xml.rpc.ServiceException;
import net.webservicex.www.WeatherForecastLocator;
import net.webservicex.www.WeatherForecastSoap;
import net.webservicex.www.WeatherForecastSoapStub;
import net.webservicex.www.WeatherForecasts;
import java.net.*;
import java.io.*;
public class TestOutput {
public static void main(String[] args) {
initialiseConfiguration();
printForecast();
public static void initialiseConfiguration() {
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "proxyserver");
System.setProperty("http.proxyPort", "8080");
System.setProperty("http.proxyUser", "userid");
System.setProperty("http.proxyPassword", "password");
public static void printForecast() {
try {
   WeatherForecastLocator wfl = new WeatherForecastLocator();
   WeatherForecastSoap wfs = wfl.getWeatherForecastSoap();
   WeatherForecasts forecasts = wfs.GetWeatherByZipCode("90210");
} catch (Exception e) {
   e.printStackTrace();
}Here, I was using the test web service located in www.webservicex.net/WeatherForecast.asmx
I've created stubs using Eclipse (package net.webservicex.www) in another project, compiled into a jar, and imported into the test project.
The test is working beautifully from my home. It's failing in the office with the error:
AxisFault
faultCode: {http://xml.apache.org/axis/}HTTP
faultSubcode:
faultString: (407)Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. )
faultActor:
faultNode:
faultDetail:
{}:return code: 407
It's failing when it's trying to execute
WeatherForecasts forecasts = wfs.GetWeatherByZipCode("90210");
The "initialiseConfiguration" function is doing its job OK - it's actually helping me to go through the proxy - if I'm doing simple stuff like accessing internet sites. I've tested it - I can get to any external site and read from it. The moment I disable "initialiseConfiguration", I can't get through the proxy.
So, probably, the problem lies in the web services client classes generated by Eclipse and based on axis. Maybe, the code gets through the proxy, but then starts to do something without authentication??? (I'm not sure if it's possible at all, but who knows...)
I've read a lot of postings on this subject and couldn't find a solution that would work for me. I'm very surprised, because my situation is very common - there are more and more public web services, and most organisations have firewalls. Obviously, I'm making some very elementary mistake.
Please help

We have the same problem, not with SOAP but with XML-RPC (err 407). We're still stumped, and i agree that the problem should be common, but i don't see the mistake, so it's not that obvious.
Hypothesis: the proxy is spying on the requests content , and filtering out xml. Can you check that ?

Authorization error calling a XI web service from Web Dynpro

Hi all,
I'm trying to communicate to XI from a Web Dynpro application but I get an Unauthorization error (401).
I've generated a WSDL in XI and import it to web dynpro as a new Model. But when a I call the web service, the exception "Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized." appears.
I don't know how to pass the right user and password from Web Dynpro, I've tried the web service from SOAP client tools and it works fine.
I'll apreciate any help.
Regards,
Diego.
