Exception in consuming Enterprise Service in CE 7.1 SP5

Hi all,
The wsdl url given below in giving exception when I am consuming this wsdl in my web dynpro application for java .
WsDL URL :
http://sapecc6.patni.com:8004/sap/bc/srt/wsdl/bndg_DE24D6FF00C574F1934E0015C5F884EC/wsdl11/allinone/ws_policy/document?sap-client=001
When I consumed this wsdl and set the destination on CE SP5 AS, its giving following error:
"Exception on execution of web service on destination INV_WS_METADATA_DEST for operation InventoryKPIPresentationService in interface InventoryKPIPresentationService."
I tried executing this wsdl in WSNavigator, both by logical destination and using URL, there its working fine, that means destination setting is correct but when itu2019s consumed in web Dynpro application its gives Exception mentioned above.
Can you please tell me what could be the probable reason for this exception .

I think you should follow this guide:

Error creating service consumer enterprise service

Hi,
I'm facing an error when creating a service consumer enterprise service using WSDL URL. I got the error message
'Exception occurred in communication framework:Error in HTTP Framework:404Not foundhttp://localhost:8000/?wsdl=wsdl0'
Does anyone have any idea of how may cause this problem ?
I've looked in existing foruns questions for a long time, and I didn't get any answer to my problem.
I'll apreciate any help.
Thanks,
Paulo Sousa

Hi,
The problem was in WSDL. It has an address 'http://localhost_8000/
They replace it by the address where the service is installed and i was able to create the service consumer.
Thanks,

XML Deserialization error while consuming Enterprise service in wd java..

Hello,
I am trying to build 2 webdynpro java webdynpro applications which consumes enterprise service for purchase order and another application for Busines partner.
While i was able to successfully consume the PO service in webdynpro java and get the desired output for PO..i get XML Deserialization error while running appliation for Business Partner..
These are the details/steps i followed for the Business Partner application:
1. After creating the model using the enterprise service, i created a service controller from the model to the component controller..
2. Out of many inputs/output attributes during mapping from model to component controller. i further mapped the context from CC to ViewC.
3. In the wdDoInit() method, i added the follwing code:
    BPCreate model1 = new BPCreate();
    Request_BusinessPartnerERPCreateRequestConfirmation_In RequestC = new Request_BusinessPartnerERPCreateRequestConfirmation_In(model1);
    BPERPCrteReqMsg_S CreateMessage = new BPERPCrteReqMsg_S(model1);
    BPERPCrteReq_SBP Cpartner = new BPERPCrteReq_SBP(model1);
String Category = new String();
    String lf = new String();
    Cpartner.setInternalID(new String());
    Cpartner.setNumberRangeIntervalBusinessPartnerGroupCode(new String());
    Cpartner.setLifeCycleStatusCode(lf);
    Cpartner.setCategoryCode(Category);
    CreateMessage.setBusinessPartner(Cpartner);
    RequestC.setBusinessPartnerERPCreateRequestMessage_Sync(CreateMessage);
    wdContext.nodeBusinessPartnerERPCreateRequestMessage_Sync().bind(CreateMessage);
4. When i comment this code and run the application, the aplication comes up but the input fields are non-editable..
5. If i place this code in wdDoInit() method, i get the Deserialization error..
Any idea about why this error occurs and which areas in the application can lead to these errors?
I checked that the service runs fine in soamanager.
Thanks, JVR

Hi Kishore,
This error is majorly because while executing this Webdynpro application you are not entering all the mandatory fileds of WS.
Please try to execute this WS from WS-Navigator, check which fileds are mandatory and then
appropriately instantiate it in wdDoInit and pass all the fields required.

Consume Enterprise Services in Java Application

Hey guys,
I'm very new in this field, maybe you can help me how to start....
I want to call Enterprise Services (asynchronous, provided by SAP) from an external java application. Therefore I want to configure a integration scenario between two business systems: java application (consumer) and sap application system (service provider). Maybe you can help me to answer the following questions.
1) What kind of adapter I have to use in communication channels?
2) Have I to define outbound/inbound interfaces for Communication Component "sender" (business system: java application)?
2) How does the communication between the java application and IS work? What kind of API I have to use - some kind of advanced adapter engine ... JCO, JCA ???
Is there any demo scenario from sap? Please help me to start
Kind regards,
Christian

Hello,
problem is you are using wsimport on web-service which uses RPC/encoding. Wsimport use JAX-WS so it is not able read it.
You should wscompile.bat instead it.
Here is example :
wscompile.bat -gen:client -d build/classes -s src -keep config.xml
(-gen:client -says to generate classes for client
-d - directory where to store classes
-s - directory where to store sources
-keep - to keep source file
xml file
Where config.xml looks like
<?xml version="1.0" encoding="UTF-8"?>
<configuration
xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
<wsdl location=
"http://something/yourws?wsdl"
packageName="org.your.package.client"/>
</configuration>
I hope it will help.
best regards

Unable to consume Enterprise services from Visual Composer

Hi,
We have implemented ECC-SE 603 add-on in our ECC 6.0 system.
We configured to set up a connection between our J2EE engine and the ES Workplace, to consume the Enterprise services from Visual Composer.
But, we are unable to see the Enterprise Services in the Visual Composer.
Kindly, let us know how to resolve this issue.

EP 7.0 Consuming Enterprise Services provided by PI 7.0

Hello Community,
A - Can we consume the Enterprise Services provided by PI 7.1 directly on EP 7.0 without using CE 7.1?
B - Assumption - The above approach is not possible & we should use CE 7.1to create a consuming application using any UI/Composition tool eg WD, VC, Adobe etc and expose that in the Producer Portal (NWCE 7.1) which in turn would be consumed by the Consumer Portal (NW 7.0). Through federation, these composite applications are exposed to the central portal (7.0).
Any thoughts/directions?
Cheers - Dhanz

Unable to consume Enterprise Service from SAP Service Registry

Hi,
I am trying to make use of a Enterprise Service available at the SAP's Service Registry (http://sr.esworkplace.sap.com/) in a Composite Application. I am using NWDS 7.1 for this purpose.
The steps that I follow are as follows.
1) I try importing the Web Service by right clicking the external node under the Composite Application and give the necessary login credentials for the SAP Service Registry.
2) I click on the "Show Advanced" link under which I make following selection:
BrowseByApplication->ERP Foundation->Business Partner Data Management->Employee
Now my problem is after I select the Employee node, the 'Next' button is not enabled on the Service Registry wizard.
Can anyone give an indication of why this might be the case. You may also want to know that at this stage I have still not installed NW AS CE 7.1.
Any help would be much appreciated.
Thanks,
Shailesh

Hi David,
Yes I was able to consume the ESOA enterprise services from SAP's ES Workplace, although I am not inside the SAP network.
As mentioned by me in my earlier post, the problem that I was facing was faced because I used to access internet through an internal proxy server which required me to pass my NT domain credentials.
In order to access ES workplace from NWDS would mean that NWDS will have to access the internet, but this used to fail despite my specifying the proxy server settings in the Preferences menu of NWDS.
I was able to overcome this problem by installing an ISA Firewall client on my m/c and in the proxy settings of the NWDS specifying a direct connection to the internet. This helped me to access the SAP's ES workplace inside NWDS, once you are able to select the available ES from the SAP workplace you will be able to utilize them in your application.
Also, once you deploy the application, the runtime, i.e. WAS will also have to be configured to access the internet, this can be done by specifying proxy settings under Global System settings options.
Hope this helps,
Shailesh

Call Enterprise service in BPM Process

Regards
Shwetha.

Hi Shwetha,
The following part of the documentation explains how to prepare your Web Dynpro DC so that it can be used in SAP NetWeaver BPM:
https://help.sap.com/saphelp_nwce711/helpdata/en/48/cae1791e774da5e10000000a421937/frameset.htm
The important thing to know is that SAP NetWeaver BPM is waiting for a complete event to be triggered in your application. Once this is received the process flow continues.
So in your case you would simply create two Web Dynpro user interfaces. The first one for entering the data and the second one for reviewing / approving / rejecting the data.
In the first case you would have some sort of "submit" button, which triggers the before mentioned 'complete' event. SAP NetWeaver BPM will then take the data that is visible in the Web Dynpro context of the interface controller and continue the processing.
The second case basically works the same with one little difference: Here you would have two buttons - one for the approval and one for rejection. Both will trigger the 'complete' event, but should set a field in the Web Dynpro context (e.g. "isApproved") differently. While the "approve" button should set it to "true" the "reject" button would set it to "false".
So once this step is also completed you could make use of gateways and conditions (https://help.sap.com/saphelp_nwce711/helpdata/en/47/635cb242bf6831e10000000a421937/frameset.htm) in your proces model to determine if the data should be passed to the service for PO creaton or if it should handle a different situation in case of a rejection.
If you're new to SAP NetWeaver BPM it might help having a look at the documentation first and also browse through some sample models as they are provided here:
https://www.sdn.sap.com/irj/sdn/nw-bpm?rid=/webcontent/uuid/006a16ad-a3ad-2b10-4e9a-af2ee5820848 [original link is broken]

Enterprise Services Queries

Hi All,
All of us know about enterprise services. I've few queries regarding that......
1) Can I access Enterprise Services without CE 7.1 or PI 7.1?
    If no, it is mentioned that SAP has delivered some
    enterprise serevies in 2006 also, then how they were
    consumed at that time?
2) Who is providing the implementation for these services?
    SAP or partners or customers?
3) Can we define a new enterprise service? If yes, any certification is required?
Technology------>
4) How these services would be impllemented ABAP or JAVA?
5) Is the tecnology for accessing/consuming enterprise services is same as web services?( soap,xml,http,wsdl)
Waiting for the answers.
Regards,
Piyush

I will try to answer some..
1) Can I access Enterprise Services without CE 7.1 or PI 7.1?
Yes, you can. You need to add the built ins
2) Who is providing the implementation for these services?
These enterprise services are designed to be used universally so the implementation is based on the requirments of the company
these are completely based on client requirments if client wants to add some service he will first check the built in services if it is not satisfied the Client Provides the implementation for these services
So the implementation completely based on the client requirments but it would be better if SAP provides implementation of these services
3) Can we define a new enterprise service? If yes, any certification is required?
You can I dono abt technology
4) How these services would be impllemented ABAP or JAVA?
Same as pi 7.0..using both
5) Is the tecnology for accessing/consuming enterprise services is same as web services?( soap,xml,http,wsdl)
Yes

Enterprise Services using PDK/JCA

Hi,
Is it possible to consume Enterprise Service provided by PI 7.1 via a PDK application in EP 7.0, does JCA support? Or should we get the WDSL generated using sproxy transaction from the ES and integrate WS in the PDK application?
We have the above requirement - so please avoid replies on CE, using VC in EP 7.0 etc
Any hints? Thanks - Dhanz

Consuming Web service : Sample ABAP application

Hi Friends,
I am trying to consume existing web service. I have few questions.
--> Why do we need to create simple ABAP application while consuming Enterprise Service?
--> How this ABAP application will be triggered? Will it be triggered automatically or this is just for testing purpose?
--> After consuming Enterprise Service , which URL my end user can use to execute the functionality ( i.e to craete PO )
Waiting for your expert responses.
Thanks,
Rashmi Jain

Hello,
Please see the responses below:
-->Why do we need to create simple ABAP application while consuming Enterprise Service?
When you created consumer proxy, you have a proxy class autogenerated. The ABAP program is to provide input data and instantiate and call the method within the proxy class.
--> How this ABAP application will be triggered? Will it be triggered automatically or this is just for testing purpose?
The program can be triggered using a Transaction or can be scheduled through batch or event based.
--> After consuming Enterprise Service , which URL my end user can use to execute the functionality ( i.e to craete PO )
The end user does not have to know the URL. This is built into WSDL from which you created consumer proxy.
Thanks,
Venu

Which product for which Enterprise Services?

Hi,
I try to test Enterprise Services with the Netweaver Sneak Preview Edition.
On the ES Workplace there are Enterprise Services documented mainly for four categories
> mySAP ERP
> mySAP Supply Chain Management
> mySAP Supplier Relationship Management
> mySAP Customer Relationship Management
Does this imply, that these four are the products, which are required to run the respective Enterprise Services?
Only two Enterprise Services are presented for the Business Solution Maps (Human Capital Management, and Supply Chain Managemnt only for Retail).
Is it in general possible to test Enterprise Services with the NetWeaver Sneak Preview Version? I cannot download the ES Addons, since a registration for the Service Market Place is required, here.
Thank you for help,
greetings, Rafael

Each SAP Product will deliver its set of Enterprise Services and act as Service Provider. Most of them will come from mySAP ERP as it's the mostly used product in the world.
You can consume Enterprise Service from Netweaver Sneak Preview (Java or Abap) as long as you have access to one mySAP ERP system which contains Enterprise Services.

Comsume enterprise service from service registry

HI guys, now I want to consume enterprise services form ECC6 in NWDS, should me publish enterprise services to service registry? and then I consume services from service registry. How should i do?thanks

Hi lei,
If u can access the ES workplace u can directly consume the service by downloading the wsdl either locally or through the service registry.To use the SR u would have to use the S user ID of ES workplace.
Just check this blog by Boris.It is a step by step approach to consume an ES wsdl through a simple java client using NWDS.
Remember to uncheck wsdl validator in NWDS before u dwnld wsdl in NWDS,else it might give an error.

Enterprise Services Explorer installation

I've installed the ESE 1.1 and its configuration options are showing up in Visual Studio 2005 Professional English Edition. I have them pointed at the ES Workplpace repository at http://sr.esworkplace.sap.com/ServicesRegistrySiService/ServicesRegistrySiPort and have stepped through the instructions in the document attached to http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c0319dc4-d76d-2a10-d19f-e4f4ff315bde.
When I get to the Discovering and Consuming Enterprise Services step in that document, however, I do not see an option for Add SAP Enterprise Service.
Is there any way I can troubleshoot this to determine why I can't see the option to add the SAP ES? Anyone else run into this problem?
Using Visual Studio 2005 Professional Edition (English) on 64-bit Windows 7, if that matters.
Thanks!

Hi Cori,
Can you please give some more informaiton ?
1. Were you able to navigate to the "Add Service Reference" step of the wizard ?
2. If #1 is true - Did your process succeeded After clicking on "Finish" ? are you able to see the .NET proxy class generated by the ESE under Visual Studio "Web Reference" folder ?
3. if both #2 & #3 are true - can you please check under the "Web Refernce" folder if a new folder exist by the name you gave it and if you choose "Show all files" you can see the WSDL's of the service & a .NET class.
Regards,
Nadav
