Call ITS Service from Webdynpro

Hello all,
Could somebody tell me how can I call an ITS Service from within a webdynpro? I've the following available with me.
System
Transction cocde
Parameters
Basically, I need to do something similar to the following (code snippet from a Portal Component)
IUrlGeneratorService urlGen = (IUrlGeneratorService)
              request.getService("urlgenerator");
com.sapportals.portal.prt.service.urlgenerator.specialized.ISpecializedUrlGenerator
                    specUrlGen = urlGen.getSpecializedUrlGenerator("UrlGenerator_SAP_Class");
if(specUrlGen instanceof ISAPUrlGenerator)     {
          ISAPUrlGenerator portalGen = (ISAPUrlGenerator)specUrlGen;
          issURL = portalGen.generateIACUrl(request, system, iac, queryString);
The background is, I've to call a transaction passing a few parameters to it from the webdynrpo. I cannot create a transaction/ITS iview because a)the parameters are dynamic b)I cannot use Portal Navigation service.
Any help is greatly appreciated.
Regards,
Rajit

Hi,
thank you for the previous answer, but I have another web service that works fine into the WebDynpro project and the wsdl file is equal to the other. Do you know if there are any activity to do from Visual Administrator about web service?
Thanks and best regards,
Matteo

Calling another ITS service from existing ITS service

Hi to Everyone,
I would like your advice on calling another ITS service from existing ITS service.
From my current ITS service eg. "Z_TESTA", i wish to call another ITS service "Z_TESTB". The problem is that it always prompt for userid and password when i called the 2nd ITS service. However, user already enter the password & id when they login to the 1st ITS service. Is there a way to call this new ITS service w/o the userid & password prompt again?
Below is the codes that we used to call the new ITS service:
(a) "http://.../scripts/wgate/webgui/!?~transaction=z_testb"
OR
(b) "http://.../scripts/wgate/z_testb/!"
We used both method (a) and (b) but same outcome. Thank you in advance!

Hi YanaJ,
in order to skip a manual login you have to have the credentials somewhere. If you disabled cookies, what I told you will not work. Another possibility would the usage of X509 client certificates. But this requires that you have a setup that distributes the certificates of all of your users. I personally nether setup such scenario. Maybe someone other can explain what you have to do.

Is there a way to call web service from 2 servers??

Hi,
I need to know if its possible to call web service from 2 different servers without having load balancer??? I mean, if one of the server has heavy work on, then it should call web service from the other server.
Thanks in advance.
Best Regards.

Hi,
WebLogic Cluster has this feature ( Load Balancing & Failover ). If you will deploy your WebService to a WebLogic Cluster and then If you will put a Proxy in front of it like (Apache)...Then it is Possible.
<h3>What All You Need To Do ? ...... as following</h3>
Step1). Create a WebLogic Cluster (minimum two ManagedServers)
http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/
Step2). Install a Proxy like Apache in frot of them like following:
http://weblogic-wonders.com/weblogic/2010/05/13/apache-proxy-as-static-content-repository/
Or
http://weblogic-wonders.com/weblogic/2010/08/01/weblogic-httpclusterservlet-proxyserver/
Step3). Now Configure a FrontEnd Host for your Cluster by providing the ProxyServer Host name as the FrontEnd of your Cluster. This step is required to Generate the Dynamic WSDL with the Address of the Frontend.(Not of a perticular WebLogic Server)
http://weblogic-wonders.com/weblogic/2010/06/21/configuring-frontend-host-and-port/
Step4). Deploy your WebService on the Cluster
Step5). Now Hit the WebService using the Proxy URL:
Example:
http://ProxyHostname:proxyPort/ServiceContextRoot/ServiceURI?WSDL

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.

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.

Call Custom Service from Event Receiver as Current User

Hello,
i bang my head on this problem for days now:
My custom web service hosted in Sharepoint 2013 needs to know the logged on user name. I used to have a self-written impersonation in my service client before, but with switching to claims authentication this should be obsolete.
So within my service i decode the user from
IClaimsPrincipal icp = Thread.CurrentPrincipal as IClaimsPrincipal;
IClaimsIdentity ci = (IClaimsIdentity)icp.Identity;
String User = ci.ToString();
This works well when i call the service from a custom aspx page.
It utterly fails when i call the service from a List Item Event Receiver. The User always is the Application Pool Account.
This is the Client code to open the Channel:
private void SetChannelFactory(
MyServiceApplicationProxy proxy,
Uri address)
if (null == proxy)
throw new ArgumentNullException("proxy");
if (null == address)
throw new ArgumentNullException("address");
// Check for a cached channel factory
string endpointConfigurationName = GetEndpointConfigurationName(address);// Get the endpoint configuration name
if ((null == s_ChannelFactory) || (endpointConfigurationName != m_EndpointConfigurationName))
lock (s_ChannelFactoryLock)
if ((null == s_ChannelFactory) || (endpointConfigurationName != m_EndpointConfigurationName))
// Create a channel factory without specifying an endpoint address
// so it can be cached and used for multiple endpoint addresses
s_ChannelFactory = new ConfigurationChannelFactory<IMyServiceContract>(
endpointConfigurationName, proxy.Configuration, null);
// Configure the channel factory for claims-based authentication
s_ChannelFactory.ConfigureCredentials(SPServiceAuthenticationMode.Claims);
foreach (var operation in s_ChannelFactory.Endpoint.Contract.Operations)
DataContractSerializerOperationBehavior behavior = operation.Behaviors.Find<DataContractSerializerOperationBehavior>() as DataContractSerializerOperationBehavior;
if (behavior != null)
behavior.MaxItemsInObjectGraph = 2147483647;
// Store the current endpoint configuration name.
m_EndpointConfigurationName = endpointConfigurationName;
private IMyServiceContract GetChannel(
MyServiceApplicationProxy proxy,
Uri address)
//Create Channelfactory
SetChannelFactory(proxy, address);
// Create a channel from the channel factory.
return s_ChannelFactory.CreateChannelActingAsLoggedOnUser(new EndpointAddress(address));
All research pointed out that "CreateChannelActingAsLoggedOnUser" would pass the current user (which is correctly identified within the event receiver!) to the service, but it doesn't work for my event receiver...
Any advice on this would be great!
With kind regards,
Joachim

You should be able to get the current user id from the SPListItemEventProperties object. From here you should be able to create a Claim. For example get the user by using
user = SPWeb.Users.GetByID(properties.CurrentUserId)
SPClaim claim = SPClaimProviderManager.CreateUserClaim(user.email, SPOriginalIssuerType.TrustedProvider, issuerIdentifier);

Calling web service from Obiee

Hi,
I want to get data from webservice and show the results in a dashboard.
I checked http://www.artofbi.com/index.php/2009/08/consuming-a-web-service-in-obiee-presentation-services-using-jquery-cdn/ web site.
But the author is retrieving data from a web page by sending parameter to querystring like

Calling Web Service from CRM using proxy

Hi all,
I'm facing a problem trying to call a web service from CRM (WAS 620) via XI 3.0. The response that XI recieves from the web service contains SOAP Envelope, and the mapping fails because of it. I built the proxy manually, because if I load WSDL the proxy generation in CRM generates error that sais that external definition coudn't be used.
Is there any way to remove SOAP envelope from the response while mapping?
Is it possible to call web service from WAS 620?
Thanks!!!!
Anya.

Hi Manish,
SOAP adapter does pass the message to XI (this message contains SOAP envelope although XI expects to get message without it), and during the mapping step i get "Runtime Exception in Message-Mapping transformatio~".
I suppose it's because i created proxy manually. I did so because when i imported WSDL, and tried to generate proxy in CRM, i got an error message that said that proxy couldn't be generated because external definitions are only allowed in XI 3. But my XI version is 3.0! And when I generate the same proxy in my R/3 system that is installed on WAS 640, it works.
What can I do?
Cheers,
Anya.

Calling web Service from the Custom Adapter.Is it Possible?

Hi Experts,
I am having requirment in which i have to cal com.sap.aii.mapping.lookup.LookupService for calling web Service from the Custom Adapter.Is it Possible?
Regards,
Rajesh.D

Hi Rajesh..
Just looking the problem in another angle.. if there is no constraint that you have to use XI specific API to call the web service, why dont you use usual Java API used for calling a web service inside you custom adapter (I have Microsoft background.. donno exactly how it is done in Java,, but in .NET kind of a language it is possible). SInce your adapter is in Java itself and is capable of calling web service.. collect or lookup the data whatever you want and validate...
Just a thought..
