ABAP Webdynpro as callable object to connect MDM Server

Hi All
if we want create MDM workflows in portal thru GP then we need to create the callable object initially which will integrate the MDM system thru MDM Apis
suppose if we choose the option of taking the ABAP webdynpro as callable object then what is the development efforts/Steps to involve for creating the callable objects.
i hope that we can use the ABAP wendynpro thru MDM ABAP APIs where we can integrate MDM data in ABAP webdynpro application.
can you please list out what is the Aims from enduser level and development level.
Please more details on this??

Theme in WebDynpro java callable object

Hi Experts,
I have created a portal theme and deployed on the server.
Now i want to use this portal theme in my WebDynpro java callable object.
I know how to use themes in WebDynpro application, set the theme in Exit plug of component interface view.
However in WebDynpro java callable object how do i achieve this?
here should i use WebDynproCOInterfaceView to set the desired theme to the callable object ?
or should i set the theme in my Componet's interface view?
i tried in both but its not working, i can still see the default theme.
Am i missing anything here?
Ashish

Hi Guys,
Any idea on this one?
Has anyone done this? are there any SAP Note for this?

What is the best approach to connect MDM server.

Hi Experts,
There are sevaral ways to connect MDM server from EP
1) Using JNDI look up
2) Throgh SystemAlias
Which one is best among performance wise, and can any body explain advantages and disadvantages
of all three.
Regards,
Sandeep.

Hi Sandeep,
Kindly go through the link below for information on

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/40ac1b5b-d33e-2b10-5892-b29c890eaa01
This article uses the method of System Alias.

http://help.sap.com/saphelp_nw04/helpdata/en/38/3e5a4201301453e10000000a155106/frameset.htm
I have done the EP integration with MDMusing System ALias. However I hav'nt done it using JNDI Lookup.
Hence it will be difficult to compare the performance of both the process. However, while working with System Alias, the performance was quite good as easily you can connect to the repository in a MDM server and then perform the User mapping. The fiurther process can be understood in the article mentioned above.
Hope it helps.

Moderator Message: There is a separate forum for Webdypro for ABAP. Please post your question there.

Hi
Few links to check:
External debugging is not working
Re: Debugging Abap webdynpro appln
Re: Unable to Debug WD ABAP application
Dedug is not working in Production Server.
a) Check on number of R/3 sessions opened at a time.
b) Check that user ID configured in portal using System Mapping Under 'Delegate User Administration' is the same user for which you are setting external breakpoint in backend system.

Need sample code to connect MDM using JCA

hi friends,
I want to connect MDM server using JCA
can you please provide me the sample code for that.

Hello Venki,
why do you want to use JCo for connecting to MDM? MDM has its own specific Java API for this task. There's no need for using JCo at all.

Unable to craete ABAP Webdynpro callable object

Hi all,
I am not able to create a callable object for a ABAP Webdynpro application.
The SAP system has been configured properly in Endpoint Aliases and the Test Connection is successfull.
The problem is that whenever I search any ABAP WebDynpro application it says "Application with this name not found". There are many ABAP Webdynpro applications on the SAP server and even if I search for * it gives me the same message.
Please help.
Thanks,
Vivek

Hi,
Is your EAR having gp/api in tis dependency. It should be added with dependency at runtime and deploy time. It should also have run time,deploy time dependencies towards your DC having the java class(Background object).
Hope it helps.

Callable objects using ABAP API

hi,
Is it possible to develop Callable objects for MDM using ABAP APIs?
Regards
Nisha

Hi Nisha,
As far as I know, itu2019s not possible. You can use just RFC/BAPI as external services CO or ABAP Web Dynpro (this CO is limited regarding output parameters).
MDM offers two APIS for Java development:
1) MDM4J API, which is an old API and will be discontinued from MDM 7.1
2) MDM Java API that is recommended
With this API you can create Java Libraries or/and Web Services to re use into your CO.

Error while connecting to MDM server from Webdynpro

Hi ,
   I am trying to connect to MDM server (5.5 SP04 no patches) through a webdynpro application . The following is the piece of code that I am using as a test .
CatalogData CatalogData = new CatalogData();
    int resultLogin = 0;
    try {
          resultLogin = CatalogData.Login("USNOC01AQ05",2005,"Admin","Erico1234","English [US]");
    }catch(Exception e){
          wdContext.currentContextElement().setValueattr("Not Connected");
         //System.out.println("Error while establishing connection");
    if (resultLogin != RC.RC_OK){
          wdContext.currentContextElement().setValueattr("Not Connected");
         //System.out.println("Error logging to the SDM server");
         //System.exit(-1);
     wdContext.currentContextElement().setValueattr("Connected");
    //System.out.println("MDM server connected");
The import statements are as follows
import a2i.common.CatalogData;
import a2i.generated.RC;
I have put the following jar files in the java build path
MDM4J
mdm-admin
mdm-common
mdm-core
mdm-data
mdm-protocol
When I deploy my application I get the following error
java.lang.NoClassDefFoundError: a2i/common/CatalogData
It can't be determined from the exception chain, which class loader failed to load the above class. But at least the class loader of the current application does not contain a resource with name 'a2i/common/CatalogData'.
What do you guys think is the problem ?
Regards
DeepaK Singh

Hi ,
   I found a document which says that MDM4J is the legacy API and is considered deprecated .The MDM Java API is the new one .I have both of them in the java build path . I am not sure if this is that cause of the problem .
Now I had a look at the javadoc for the new API but I am not able to locate the class to obtain a connection to the MDM server from a custom application being built in Netweaver Developer Studio . Can someone help me out with the same ?What would be the code to obtain the connection to the MDM server with the new JAVA API ?
Regards
