BAPI Web Service Context Mapping Problem

Hello all,
I am developing a process consisting of an automated activity.
This automated activity uses a logical destination for a web service call to an ECC BAPI.
The BAPI name is 'BAPI_INQUIRY_CREATEFROMDATA2'
Now the problem is the Output mapping in the automated activity which calls the web service for the above BAPI has the response name as 'BAPI_INQUIRY_CREATEFROMDATA2.Response'
So when i try to map the nodes it gives me an error, 'Error at Line 2, Column 29, Found '.' after BAPI_INQUIRY_CREATEFROMDATA2'.
Since there is no mapping i do not get the process working
If i remove the '.' from the wsdl file source, mapping is done. But the backend service call gives an error.
How can i solve this problem?
Any inputs will be very helpful.

Hello Martin,
thnks a ton for your replies.
The '.' is a standard thing.
Its the part of the WSDL file which is a standard WSDL file for a service offered for a standard SAP BAPI. So i haven't changed anything.
Its what is standardly available. So i cant anything on that.
And the response element is not below the bapi node.
The name of the root node of the BAPI return context is
"BAPI_INQUIRY_CREATEFROMDATA2.Response"
This is what is causing the problem.
Please note here that '.' is not responsible for any hierarchy. Its the name of one single root node element.

Create, get and update web service context mapping

Hello,
I think I have a pretty common problem. I will explain it with a simple example:
I have a car object, with the attributes id, name and speed.
I have three web services: create, get and update
I have a view with the input fields id, name and speed
How to do the context mapping?
When creating a car it would be good if input fields would be mapped to the create service, when getting a car it would be nice if the input fields would be mapped to the get service....
How to deal with this situation? Do I have to create 3 views?
Thanks!
Felix

Web service empty relationship problem

hi all,
I have a pretty simple web service. Two entities, a citizen and a business. A citizen is able to register 0..n businesses. There is a WS which reads the citizen. When the business key list in citizen is empty the web service wont return the citizen (portal request failed could not execute web service operation). When at least one relation is defined all works fine.
I've tested the web service. The problem occurs only with VC.
thanks for your help,
regards, felix

Hi Ankur,
no, not exactly...
The webservice is tested with an id as input and returns some string values (name, firstname...) and a list of references to other objects. When this list is empty...(depending on the back end system)
part of the SOAP message:
<ns1:businessRef xmlns:ns1='urn:com.sap.bureg001.core.besrv.citizen' xmlns:pns='urn:java/lang'></ns1:businessRef>
... visual composer returns an error.
when this list is not empty (again depending on database entries in the back end)
part of the SOAP message:
<ns1:businessRef xmlns:ns1='urn:com.sap.bureg001.core.besrv.citizen' xmlns:pns='urn:java/lang'><pns:String>c22bc900-dec3-11db-cdce-00505625e523</pns:String>
</ns1:businessRef>
... visual composer does not return an error but returns the values like the service is supposed to do.
Testing the web service with Web Services Navigator both scenarios are working without problems.
thanks for your fast response,
felix

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?

Web dynpro welcome example edit context mapping problem

hi,
i tried to build a web dynpro like the welcome example from web dynpro.
so i created the views etc, created an atrribute matnr in the context of the component.
then i connected the other views with the component. for this i used the required controllers.
so, now i created a attribute nr in the context of the other view and wanted to connect it with matnr from beginning with edit context mapping.
but in the shown context is not the attribute matnr. there is no attribute.
any idea what went wrong or is there something that i missed?
thank you

Hi Marcus,
Do one thing Create Value Attribute under Context like(matnr). Next Right Click on Webdynpro Component Click on Open Data Modular that time it will open data modular View. Here we are doing Context Mapping to Component Controller to View Controller that time Same Value Attribute will be created in View Controller also.
In context mapping, the actual context data is saved only once in the original node. All other context nodes that are mapped to this original node reference the same contents, without having to save it again, for example using copies. In this way, inconsistent context contents are avoided.
Please look at this simple WDJ Application. http://help.sap.com/saphelp_nw04/helpdata/en/bc/e4d61774174344a4b126ad07e8c230/content.htm
I hope this is help full for you,

Best Practice Web Service Output Mapping (deep structure)

Hi All,
My current scenario is as follows:
In my BPM I consume a Web Service which was created from a Function Module in the Backend.
This Web Service has the same Data Types as the original BAPI.
For instance a table containing return values (BAPIRET2).
When the Web Service inside the process is executed I assume that my return table is filled.
Based on that return table I want to decide what to do next using a gateway.
What would be the best way to process the table in a gateway condition?
The table may contain several entries so I guess a simple not() function does not suffice.
I hope you do understand my problem here.
Curiously waiting for your replies,
Bastian

Hi Bastian,
the parallel for each loop feature will come with NW 7.2.
You will have a new property pane at each activity (automated activity, human task, referenced subflow, and the embedded subflow which will also come with NW 7.1) where you can switch on the looping.
If you do that, the activity will be started (in parallel) for each line item in a list of data from a data object in the context (the list can also be specified in the new property pane).
At the end of each activity execution the result can be mapped via append into another DO from the context.
Unfortunately, this feature is too extensive to be downported to 7.11
Best regards,
Oliver

Web service client JAR problem

If want to know in which layer is the problem or what is the problem.
Thanks

I'm only just scrapping on the surface of SOAP myself, but I have a little Java knowledge.
I think your error message is saying, that your trying to send a java object over SOAP to the other computer, but this object has not implemented the serialize interface (where objects are written and extracted to a stream)
Just a thought I could be wrong - but have a look at what object is being sent over SOAP - is it a custom object? does it need to implement serialize?
Good luck

Web service model initialization problem

Hello, every one
I have some trouble in the initialization of web service model.
I tested the web service through web service navigator and it was ok.
My context structure is:
Request_ZBAPIWCALIST_zbapiWcalist(0..n)
--parameters(0..1)
rBdate(0..n)
high(string)
low(string)
option(string)
sign(string)
--Response(0..1)
Result(0..1)
tWca(0..n)
estat(string)
istat(string)
Following is my codes:
Request_ZBAPIWCALIST_zbapiWcalist model = new Request_ZBAPIWCALIST_zbapiWcalist();
ComplexType_ZbapiWcalist parameter = new ComplexType_ZbapiWcalist();
model.setParameters(parameter);
ComplexType_ZbapiRBdate rBdate = new ComplexType_ZbapiRBdate();
ComplexType_ZbapiRResp rResp = new ComplexType_ZbapiRResp();

ComplexType_ZbapiRWapinr rWapinr = new ComplexType_ZbapiRWapinr();
ComplexType_ZbapiRWapius rWapius = new ComplexType_ZbapiRWapius();
ComplexType_ZbapiWcalistImport wcaImport = new ComplexType_ZbapiWcalistImport();

wcalistBean.setRWapinr(rWapinrArray);
wcalistBean.setRWapius(rWapiusArray);
wcalistBean.setWaImport(wcaImportBean);
wdContext.nodeRequest_ZBAPIWCALIST_zbapiWcalist().bind(model);
The exception is:
LocalizedMessage: Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.XmlMarshalException: XML Serialization Error. Property [Low] of class [com.pjs.wcalist.model.wsmodel.proxies.types.p1.ZbapiRWapius] must exist and can not be null. This is required by schema description.
In the test of the web service the Low of the ZbapiRWapius is not needed.
And after setting the value, the exception told me that I must set the tWca, ie the subnode of the result.
The problem is: I do not know why the setter method of the original bean of the "parameters" only accept the parameter of array type .
I think the parameter I set may be wrong.
When I deal with another web service model(the level of the structure is not deep), it is ok.
Could someone give me some suggestion or explanation?
Thanks a lot.

Hi,
I guess one of the biggest advantages of the WS Adapter is the support for WS Reliable Messaging.
Here are some documentations about this Adapter:

External context mapping problem

Hi,
I am trying to create a sample application for external context mapping
1. I created a webdynpro project.
2. In that project i created 2 web dynpro components PrComp and ChComp.
3. In the ChComp Interface controller context created a node MappedNode with attribute text.The node property isInputElement is set to true and also the carinality to 0..1
4. Added the ChComp as Used Component for PrComp.
5. Mapped the context of the ChComp Interface controller to ChComp Component controller and PrComp component Controller.
6. In the ChComp Component controller, i initialize the node atribute text with some value.
public void wdDoInit()
    //@@begin wdDoInit()
     wdContext.currentMappednodeElement().setMappedText("Mapped Attribute");
    //@@end
7. In the PrComp component controller i create the ChComp and try to retrieve the value of the node attribute text.
       public void wdDoInit()
    //@@begin wdDoInit()
     wdThis.wdGetChildCompComponentUsage().createComponent();
     String text = wdContext.currentMappednodeElement().getMappedText();
     wdComponentAPI.getMessageManager().reportSuccess("mapped value "+text);
    //@@end
When i deploy and run the application i get the following error
java.lang.NullPointerException
    at com.sap.tc.ram.sample.external.context.mapping.ChComp.wdDoInit(ChComp.java:98)
I am creating this app as a sample for external context mapping.please tell me if i am doing the rigth thing.

Shiram,
Your code will not work until you remove any node access from wdDoInit in ChComp (step 6).
Think about the actual execution sequence:
1. PrComp creates usage of child (ChComp) via createComponent
2. ChComp get initialized internally by WD framework, as part of process ChComp.wdDoInit is invoked
3. Context mapping is applied parent(source) <->child(target)
So step [2] happens always before [3], you didn't alter this behavior via cardinality as suggested by other readers.
What you can to do?
1. Do not use wdDoInit of ChComp to populate / access data. Populate data from PrComp instead.
2. Do you really need isInputElement? Think about it. If you remove isInputElement setting in child, then create mapped node in parent, then node in child will be source of data and you may safely populate it ChComp.wdDoInit.
And, as other pointed out, cardinality still can cause error -- you are using 0..* but not creating element manually. Either set cardinality to 1..* or create element in wdDoInit of "source" controller (PrComp for [1], ChComp for [2])

Accessing BAPI web services from CAF External Services

We have wsdl files that corresponds to BAPI calls. Using CAF, we want to create an external service using those wsdl files and then create an application service which will be in turn used by web dynpro for developing our composites. We did the following steps:
1. Created a new Composite Application Service project
2. Then right click on the External Services, select import, choose Web service.
3. Select 'Local File System or URL' option. Copy the URL from the wsdl file and pasted the URL in the 'Browse' text field and click Next. Got an error in loading the web service.
4. Removed the Proxy Server settings in Developer Studio but in vain. Tried all possible combinations with the URL also (such as with and without the wsdl key at the end of the URL and using the 'UDDI or URL' option under the Proxy Definition of the External Services Import and also with the Window => Preferences => Proxy settings).
5. Since the above options failed, copied the wsdl files to the local drive and then choose that WSDL from the file system. Able to import.
6. Created the application service and provided the custom code for the request and response.
7. Registered the external service in the CAF browser -> Administrative tools -> External Service Configuration
8. Tested the service through the Developer Studio.
The error I get is: ERROR: IOError while working with the message. Check the nested exception: Connect Refused: connect:
Any idea on what needs to be done to resolve it?

authentication is required at design time to read the wsdl from bapis. did you provide username and password when importing the web service.
you can always add the username and password to the url to see if you can successfully get to the wsdl. Like that http://<webas_abap_servername>:<portnumber>/sap/bc/soap/wsdl11?services=BAPI_PO_CREATE&sap-client=<clientnumber>&sap-user=<username>&sap-password=<password>

Sample code to access BAPI Web services from JAVA required

Hi All,
I am a java developer. I am new to SAP. I just want to know how to use the web services from ABAP
I got the WSDL, and able to convert the WSDL into java classes using java2wsdl command.
Now i want to know how to use these classes, in my java class. i want to know two things
1) How to get authentication or session or token to use the service
2) How to consume BAPI services by using above session or token.
Any help, really appreciated. Plz help me if any one knows.
Thanks alot,
Mohan

Hi,
I have a web application developed with java,jsp and javascript and server used is weblogic.
Now this application is running fine on my PC. I assume from this that there is no client side Java. Is this right?
So what steps are required so that I can access the application from other PCs also.If there is no client side Java then you have to do nothing other than make sure your PC can be reached from the other PCs. i.e. no firewalls blocking the access and routing available between the client PC and the server PC.
I don't see what this has to do with JNLP. Am I missing something?

Web services Context

Hi,
I need to use a shared context to hold the application session across various web service invocations. I found WS-CTX (http://docs.oasis-open.org/ws-caf/ws-context/v1.0/wsctx.html) supports that. But I am not sure of how to implement it.
Can anyone help with me the details? (with sample code plz :))
Does Axis supports WS-CTX?
Thanks
Ajay

no.
we don't expose ServletContext for now

Web service request formatting problem

I'm trying to create a few interfaces to work with some web services that we have published within our organization. Creating the web service reference seems to go fine. We had to work through the details of getting that working over SSL and we seem to have gotten past that hurdle.
Problem is that when I either test the web service reference through the testing page of the Apex app builder or attempt to call the web service from a page built on the web service reference I'm getting an error indicating that the XML of the SOAP request isn't properly formatted. Specifically, it seems that Apex is inserting an extra double-quote at the end of each element tag for all the input parameters.
So I have this:
<SOAP-ENV:Header><ns1:parameters xmlns:ns1="urn:GetIncidentTest"><ns1:userName">
Notice the double-quote at the end of the userName element tag.
The error message says:
Element type "ns1:userName" must be followed by either attribute specifications, ">" or "/>".
So it's seeing the double-quote where it's not expected/supposed to be and returning an error.
It would seem to me that Apex must be putting that extra double-quote in there at request time, since the web service definition (the WSDL) seems to return all the proper parameters all neatly layed out in the testing page and any other pages I build off the service definition.
Anyone got any ideas on this?

Jeff,
That text() thing came from the Oracle magazine example. I've been looking in the documentation for an explanation of what it's for but haven't had any luck finding anything yet.
