Problem in Web service callable object!!

Hi,
I have created a function module in R/3, and made it RFC enabled.Now i am trying to use this webservice in creating CO for web service.Now when i test it, i am getting this error:
Web service method http://<hostname>.<fully qualified domain name>.com:8001/sap/bc/soap/wsdl11?services=ZADDITION&sap-client=400&sap-user=<user ID>&sap-password=<Password>
invocation failed: Invalid Response Code: (401) Unauthorized. The requested URL was:"http://<hostname>.<fully qualified domainname>.com:8001/sap/bc/soap/rfc"; nested exception is:

What can be the reason??
any help will be highly apprecaiated!!
Thanks & Regards

Hi,
Yes i am getting error Could not find logical destination interfaces, check the <b>WSIL URL</b> inserted in visual admin.
Look.,
1)my function module name is ZADDITION,(RFC enabled)
2)IN transaction WSADMIN, i got the URL as
default_host/sap/bc/srt/rfc/sap/ZADDITION
in visual Admin i put this url
http://<host><fully qualified domain name>:8001/sap/bc/srt/rfc/sap/ZADDITION?sap-client=800&wsdl=1.1,
please tell me this host name is R/3 server or the portal server?
IN visual admin i put the above stated url,inserted SID,client,language, Basic Authentication,given UIDPW,
Then in Design time i was able to fine Logical destination name : Exposing,
then i clicked on search. but nothing happened
What can be the problem..is there any problem in my url??
please guide me, i think we have almost solved this..You have helpd me a lot..

MessageArea UI element usage in a Web Dynpro Callable Object

Hi,
I have to use a MessageArea UI element in a view of a web Dynpro callable object,
but when the callable object is showed, this message Area is always empty.
what is the problem?
Can anyone help me?
Regards
Luca

Your callable object do have a webdynpro view with a message area as well?
From my understanding when there is 2 view display at once, only 1 message area is required, if both view are having message area, the message will not display.
I found this senario when integrate my webdynpro component with the FPM framework. When my view is having message area, the message derive from message manager will not show at all. However once I remove the messae area the message shows in the FPM application area (example employee search)
What I did is to remove the message area UI element in my view when it hits certain condition.
IWDTransparentContainer rootContainer= (IWDTransparentContainer)view.getElement("RootUIElementContainer");
if(your condition)
rootContainer.removeChild("MessageArea");

Error testing Web Dynpro Callable Object (GP Interface)

With reference to thread:
Interactive form as Callable object error on testing the object.
FYI, I'm running NW04s, EP 7.0 SPS 13, JDK 1.4.2_14, Unix OS
Hi All,
I have created a Web Dynpro App with a Adobe Form as the frontend. I have included the caf/eu/gp/api as a DC and implemented the IGPWebDynproCO interface. Next I created a Web Dynpro Callable object in GP and ran a test and received the following error:
Result: Technical Exception
Details: Could not create web dynpro callable object component
Output Parameters
Callable object implementation did not return output parameters
Can anyone help me resolve this? Do I have to make a manual entry in the HOST file? If so, what is that entry? Are there alternatives?
Thanks
Kunal.

Hi,
For creating WD callable object you need to add following three DC in your WD DC project.
In the Web Dynpro Explorer of the Web Dynpro Perspective, expand the node DC MetaData -> DC Definition, and select Used DCs.
a.      To create a DC dependency, open the context menu and choose Add Used DC.
b.      Select Local Development -> SAP-EU -> caf/eu/gp/api/wd -> DC MetaData -> Public Parts -> GPWebDynproCO. For Dependency Type, select Build Time, Design Time, and Run Time. Choose weak from the dropdown list.
c.      Repeat the previous step to define a dependency to DCs SAP-EU-> caf/eu/gp/api (public part external) and SAP-JEE -> com.sap.security.api.sda (public part default).
You need to do one more thing like bellow.
Select your Web Dynpro project and open its context menu. Choose Properties.
1. Choose Web Dynpro References -> Library References.
2. Add a reference for library caf/eu/gp/api.
I think this will help you.
Thanks

Hi,
since I did not find that BAPI in my system: what is the exact name?
Did you test the BAPI directly in ABAP, i.e. function builder SE37, successfully?
Currently it looks to me as if you did not provide sufficient business data.
Did you specify the employee number before executing the call?

Help NeEDED. How to link to soap web service from objective c

Hello , HELP
I'm trying to connect to a SOAP based web service using objective C as my programming language. Although the little bit of information on the Apple Dev centre documents is should be straight forward, im struggling like **.
What im trying to do is connect via a small username and password text-box plus 'login' button from interface builder to
https://api.betfair.com/global/v3/BFGlobalService.wsdl and parameter called login.
then pass it my username and password from the interface text-boxes plus a few other standard set bits of information which are required.
in turn the soap request will pass back a session token which i need to store.
I've tried using WSMakestubs, which builds successfully the classes, but when calling them method nothing happens.

Hello Etresoft
Thanks again for coming back to me.. I would like to add that maybe on my first thread i wasn't as clear on what i was asking for, and also what avenues have have stepped down before asking for help.. Believe me i hate nothing more than not being able to resolve something myself. I'm currently reading 'another' programming in cocoa book by Arron Hillgrass, although he touches on the web service call to a Amazon web service example, he doesn't go into detail about how to actually do this.
So again thank you for trying to help me.. its greatly appreciated.
Ok back to the subject, and your response below.. I will try and be as informative as i can.
I'm want to create a application using the interface builder which has a username and password textfield plus a button called <login>..
On entering the username and password and pressing the login button, i was to send a request to the a .wdsl (SOAP) web service and login.! the webservice in return will send back a session token, which i need to store for further web service calls.
In xcode i have been trying now for 1 week..!!! and the more i read up on how to make the Soap request call the more i fail to understand if this is simple or complex.
* A bit more info if i may, on clicking the login button i need to send information to the below address as a soap type request.
https://api.betfair.com/global/v3/BFGlobalService.wsdl
i need to also tell the request the method name which is loginreq
and also i need to pass these parameters in the request.
username (from textfield)
password (from textfield)
productId = '82'
vendorsoftwareId = '0'
locationId = '0'
ipAddress = '0'
The stage I've got to is, I've used wsmakestubs and I've tried 'wdsl2objc' to create the classes required. I have then created a app controller class and a interface build app with the textfields and login button. I have then linked up the textfields and button to the nsobject appcontroller with a action ibaction loginreq etc. On build and go the app builds without error's but fails to do anything when i press the login button.. (more i think about this the more i think its either two things, one im not passing the parameters and two im not invoking the loginreq method from the class.)
I feel like im wading in treacle and getting nowhere fast.!
All i would like is for some help from someone to point me the correct direction..
Im thinking that with all the Soap web services out there in the WWW, this must now be a easy thing to do in xcode. Im starting to think im stupid..
Thanks again for you Help
Regards

Web Dynpro Callable Object : use of RFCs

Hi All,
I've to create a callable object using Web dynpro.
In this web dynpro to display a table data populated by calling RFC and we need to select one row of the table and sent it as output parameter.
My question is how we gonna set the getDescription Method in this case for creating the Callable Object?
How we define the execute Method in the Interface Controller.
Where I should bind the Model to Controller (Component Controller / Interface Controller)
Can someone explain how we gonna use RFC in Web dynpro while calling it as Callable Object.
Thanks
Srikant

Hi,
You need to have the SCs for local development of Web Dynpro callable object.
Refer the following documents for more details:

Life cycle of a web dynpro callable object

What is the life cycle of a web dynpro callable object.
Means when that Web dynpro callble object is used in a GP process which method of that component called first and what is the sequence of the method execution in that.
Can anyone please explain me.

Sorry ritu there was one mistake in the above two replies.
The actual execution of the methods when a callable objects is get executed is as following
1.component controller's init() method
2. interface's init() method
3.view's init() method.
4.interface's execute() method
5.view's wDoModifyView() method.
If you want to change anything on your view according to the change in the interfac's execute method.
Then you have to do that coding in view's wDoModifyView() method.

Date type attribute in web dynpro callable object

Hi all,
I am creating a callable object with date type attribute as input parameter in a web dynpro callable object.
date type I have used is java.sql.date.
But when I am exposing that callable object in GP its giving an error:
Technical Exception:
Web dynpro Component cannot be created.
And when i am changing date type as java.util.date then I am not able to asssign that date attribute in my view layout.
Can anyone plese help me.

Hi Ritu ,
u have to convert the util date to sql date in the execute method .
do it as showm below in Execute method in the component Controller :
let the Attribute be planEndDate in the Context:
public void execute( com.sap.caf.eu.gp.co.api.IGPExecutionContext executionContext ) {
java.util.Date planEndDate = null;
planEndDate = (java.util.Date) inputStructure.getAttributeAsDate(IContextElement.PLAN_ENDDATE);
java.sql.Date sqlDate = new java.sql.Date(planEndDate.getTime());
wdContext.currentContextElement().setPlanEnddate(sqlDate);
Thanks and Regards

Reusing the same web dynpro callable object

I have created a web dynpro callable object and I want to reuse the same callable object in all the actions of that process.
I am getting the current action ID in execute() method of interface controller in WDP callable object.Now I want to generate screens for different actions based on that actionID.
for Ex if(actionID ="1")
fireplug to second scrren.
else
to next screen
But I am not getting where to write this If eles condition to get different scrrens at runtime according to the actionID.
Can anyone please help me.

hi ritu,
to get the input and output parameter of the callable object in your view you do the following things.
1.you create the context elements in interface controller.
and assign the values of input parameters of the callable object, to the interface controllers context attribute value. using the following code.
IGPStructure input = executionContext.getInputStructure();
wdcontext.currentContextElement().set..urattribute name=input.getAttributeas..type of the attribut("specify your input parameter");
2.then map the context elements of interface controller to component controller,and then component controller context to view context.
Then we will get the input parameters of the callable object in view.
If you want any further clarification on this please explain your scenario detailly.

Problem with web service that returns an object with a String that have som

Hi everybody:
I have a problem with a web service I am doing, I have made a web service that returns a collection of objects, the objects have a set of properties, there is one property that is a String,this property consists in a text fragment that could have some characters that are considered special in XML like &, <, >, " and that's why when I execute the service from a client an exception is thrown:
{code}

Hi,
BPEL and BPEL PM do not have a good support for SOAPENC-Array: it would be very difficult to create such an array in BPEL or to receive it and manipulate it.
The (unfortunately very intrusive) work around is to change the WSDL of the service to use a XML type defined using XML schema. This is all the more painful that JDev 9.0.4 does not have strong support for complex types.
In general though, I would highly recommend this best practice:
1) Start by define the WSDL contract first
2) Then generate the server side skeleton to implement it
3) Use BPEL as the client to this contract.
By starting with the contract first, you make sure that 1) your interfaces are clean and coarse grained.
2) things like java objects, sessions, etc to not leak through the interface (which would be the worst thing that could happen because it would closely link the client and the server.
Sorry for not being more helpful. This will get radically cleaner in Oracle AS 10.1.3.

and I have to run the web service then it shows
the dash board made from Xcelsius very well.
but when i change the path of same web service to other m/c then flash file does work and it gives message
"Can not access external data"
but in practical my web service path can be changed, it should not fixed for path which is given in data manager in Xcelsius.
I am using Xcelsius Engage 2008 sp3
please give suggetions for solve the problem
thanks in advance

Hi Venky CRMIT, Bruce007
Aside from the question, I tried another methods and I have succeeded calling webservice. A reference URL is
http://www.webbasedcrmsoftware.com.au/crm-on-demand-tutorials/65-java-access-to-crm-on-demand#_Toc224720963
Main cause may be jsessionID as you guess. When I try with EAI, I have send login information and message call at once, so URL may be incorrect.
Thank you for your help.

Problem in creating a callable object of type Business Logic

Hi SDN,
I am trying to create a callable object of type Business Logic in CE.
When I give all information and click Next, I get this error message.
Error while loading configuration dialog: Failed to create delegate for component com.sap.caf.eu.gp.ui.co.CExpConfig. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)
Can anybody help me out with this problem.

Hi.
I'm having the same problem as Senthil in NW2004s SP15 with my application service and methods not showing up in the Callable Object wizard for Composite Application Services after I choose the Endpoint. The only application name that shows up in the wizard is caf.tc, and the only service names that show up for it are LDDataAccessor, Metadata, and PropPermissionService.
My IDE is on one machine and the application server I deploy to is located on a different machine. My endpoint to the remote application server looks to be correctly configured. The Composite Application Service seems to be deployed properly as I'm able to see it and test that it works in the Web Services Navigator <http://remotehost:50000/wsnavigator/>
My deployed application service is a remote enabled service and is also web services enabled as well.
I'm not sure if this is relevant, but I noticed that the generated Java code does not create any remote EJB interfaces (only home and local interfaces were generated).
Something else I noticed is that when I proceed to the External Service Configuration -> Business Entities screen <http://remotehost:50000/webdynpro/dispatcher/sap.com/cafUIconfiguration>, I only see three business entities displayed, and the following error message is displayed: "Corrupt metadata has been detected. This may prevent some objects from being displayed. Check the server log for more details." I was unable to find anything in the instance log files. Is the error message indicative of the problem?
I am developing locally without a NetWeaver Development Infrastructure (NWDI) in place.
I'm wondering if the credentials specified in the endpoint require any special roles or privileges.
Senthil, do any of these additional descriptions apply to you as well?
