Error while testing the created entity service

Hi
I have an error "access forbidden.please login again" while testing the entity service in the service browser.Please help.

Hi,
I think this is not a problem from your end. You please check for another entity service. If you get the same error then this is the problem from server side. If possible please restart the server and try it again.
Thanks

Hi Samir,
you could be right...
it could be, that our metadata are inconsistent, because we had before problems with the automatic code generation.
What should we do, if we have such a inconsistency of our ejbmodule, dictionary and metadata model?
is there a way to repair the project?
Undeploy and Redeploy doesn't have an effect on this.
We cannot start again, because we put in 10days of development?
Thanks for any help.
Greetings Jens

Error while "Project Code Generation" in Entity service

Hi SDN's,
I have created an entity service which is the help documentaion of NWDS. After completion of all steps while generating project code i am getting an error called "AbstractStringBuffer not reachable"
Can any body help me in solving this issue.
Thanks in advance

Hi Raju,
it seems like you have a version problem, try to use jdk 1.4 or higher and try.
Or go to
Prefrences --> Java --> Installed JRE's here change the Jdk to the latest,compatable version
Sometimes reinstallation also solves such problems.
Award pts if help full

Hi Chandan,
Can you do person.getRelatedModelObjects() and get the contact object, to check whether it is null, also check in the CAF DB whether the data you entered is present.
I am not sure the code is actually adding the contact model object to person.
Go thru this SDN Blog on usage of the CMI API's, there is a link for CMI documentation in it which might help you get the right code for adding the contact object.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/cef4f43e-0d01-0010-db84-ede25c874115.

Hi Ritu,
The problem is due to the version of NWDS you are working on. If its an older version like 7.0.0 please try to upgrade it to 7.0.9. With this the problem would be solved.
You can try by deleting only the .metadata folder in the following path
D:\Documents and Settings\user\Documents\SAP\workspace
If still the problem exists the only thing you can do is reinstalling the IDE. before reinstalling it be sure that you completely delete all the workspace, .dtr and .dtc folders.
All the best...award if useful

Access to Entity Service from Portal Application

Hi Experts,
I have a hybrid application which will be making use of both Web Dynpro and Portal Applications. I decided to use Entity Services to store my back-end data and can access it fine from the Web Dynpro project. I have included the public part of my CAF project into the Used DCs of my Portal project and while I am able to call the methods of the Entity Service at compile time, at runtime I receive an error message on the page:
An exception occurred while processing a request
I know in order to get this to work for Web Dynpro I had to include sap.com/tccolapi.sap.com/cafruntimeuicouplingapilib as a Library Reference and a few Used DCs, but while I have added the Used DCs to the Portal project, I am unsure of how to add the Library Reference. I assume this has to be added to portalapp.xml, but I don't know the syntax.
Could somehow please reply with how to do this and whether this is all that is required in order to call Entity Service methods from Portal applications?
Thanks,
JP

Hi Smith,
Write click on the Project then goto the Properties=>Webdynpro References=>Library references
add
caf/eu/gp/api
sap.com/cafruntimeuicouplingapilib
And add the following DC in your project.
1> External in caf/eu/gp/api (CAF domain)
2> caf/eu/gp/api/wd (CAF domain)
3> com.sap.security.api.sda (SAP-JEE)
portalapp.xml
<?xml version="1.0" encoding="utf-8"?>
<application>
<application-config>
<property name="SharingReference" value="usermanagement, knowledgemanagement, landscape, htmlb, exportalJCOclient, exportal, SAPJ2EE::library:cafeugp~api"/>
</application-config>

Error calling web service from Viusal Composer

Hello:
I'm accessing entity services methods published as web services from a composite application from Visual Composer. I'm using version 7.0 SR3 SP15.
Iu2019m able to access create and read methods from entities services. But from same getAll() methods Iu2019m getting access error. When I execute the same getAll() method from u201CWeb Service Navigatoru201D it works ok. But from Visual Composer itu2019s not working. That happens only for same entities for others itu2019s working ok.
From VC Iu2019m able to select the WDSL and use I in the iViews. The other methods of the iView works ok except for the getAll.
I have already set the options of VC to not keep a cache of web services definition and review and recreate the system in portal landsacape and teh related alias to access the web services. I have laso checked te user and password in the mapping.
Thabk you in advance for your help.
Regards.

Hello:
Using the infprmation in the link that you pass me I was able to look into the log files and see what the problem is.
The getAll service as it is geerated by NWDS receive an input paramter:
queryFilter (test.types.p1.GetAllQueryFilter)
In VC when I drop the getAll method from the corresponding service data into the working area. That input parameters doesn't apper aonly the output parameter.
Then when I execute or test that service. The portal is giving an error:
Full Message Text
com.sap.engine.services.webservices.additions.soaphttp.exceptions.ProcessException: Cannot find the required parameter [queryFilter] in request message
But that parameters was never recognized by VC.
Thank you in advance for your help again.

Entity Services: readByCustomKeys operation mapped to External Service

Hello *,
in my CAF application I'd like to read a product from SAP PLM. Within my Entity Service materialNumber is my custom key and therefore a corresponding operation exists: readByCustomKeys.
I map this operation to my External Service (Web service provided by XI).
As I can't test this operation directly with the Service Browser (deosn't appear there), I wrap my Entity Service with an Application Service where I use the readByCustomKeys operation from Entity Service.
Now when I test the Application Service operation I get the following error message in Service Browser:
ERROR. Invalid type value :
In XI I can see that there was no error and I got well defined XML data as response. So the problem must occur anywhere in the mapping back from External Service data to Entity Service attributes.
Wrong data type mapping can be excluded as I already tested this possibility.
Does anyone know what could be the reason?
Thanks for your answers and best regards
Joschi

Hello Joachim,
I dont have a lot of experience with readByCustomKeys (one experience which failed) but uou can also use read itself. If you have defined materialNumber as a key in your entity service, then this field can be used in read operations as well (I have a lot of positve experiences with this approach). You will find materialNumber while mapping read with your external service and you need not map the key field generated by Entity Service.
For testing entity services, we have had several positive experiences with the config browser, specially for a findBy, read and even update operation. It was very easy to have a prototype UI to check the entity services.
I know this isnt the answer to your question, but just sharing my experiences.
All the best!!!

Parag.

Table Name Issue of CAF Entity Service

Hi All
I have a problem in the following scenario :--
I have created a CAF project named xflit_01 in local development. Another CAF project xflit_02 is created in local development of another machine's NWDS but both the project has a same entity service name,'Flight'. But one interesting observation from persistency tab of the entity service'Flight' is that for tables generated for both the entity services are same name, 'XAP_XFL_FLIGHT0001' where "XAP_XFL_" is namespace and "FLIGHT0001" is names. Both entity services are mapped with same external service.
Next I have deployed that two projects such as xflit_01 and xflit_02 in same central WAS from different machine's NWDS one by one. but how two tables with same name, 'XAP_XFL_FLIGHT0001' would be handle by WAS? But after the deployment we need to configure external service. So in External Service configuration window we are getting error when the link Service Registry is clicked.
Any idea will highly be appreciated.
Thanks
Chandan

Solved by myself. Reason is for same db and CAF table naming convention
