Significance of the "JCO RFC Provider" service

[Former Member]

Dear SDN Community,

Can you please tell me the signifacance of the "JCO RFC Provider" service in Visual Admin. How I can make use of this service to connect to R/3 in my Webdynpro application. My thought is, to connect to the backed, we create the JCo destination in the Webdynpro Content administrator using SLD connection and use them to import the models into the project. Can you please share your thoughts here.

Thanks!

Surya.

Hi There,

In Order to Connect to R3 from Web Dynpro first thing

you need to have is Technical System of type "AS ABAP" in the SLD.

Next, WebDynpro provides Wizard for Connecting to R3

through Create Model Dialog. (Adaptive RFC)

After that you need to go to WebDynpro Console and Configure the JCO

which are created during the Wizard.

Cheers !

Thank you all for your inputs. Can you please tell me for my Webdynpro(Java) application to call an RFC is the servive "JCO RFC Provider" plays any role ? Can I ignore configuring this service and still can connect to R/3 using a ABAP technical system defined in my SLD.

Thanks!

Surya.

Hi Surya ,

Once your ABAP Technical System is Defined in SLD , then

you can straight away start writing WebDynpro Applications using java.

No need to worry about JCO RFC Provider .

Hi Surya,

While creating a model you need to provide modeldata and metadata destination and thus it needs to be configured to connect to you backend and can't be ignored.

Hi Surya,

We create 2 destinations one for modeldata and another metadata. The metadata destination is used for the getting the metadata(data about the data) like structure of table, datatypes, etc. While modedata is used for getting the actual data stored from the backend.
