SAP R/3 - J2EE Application interface using XI

[Former Member]

Hi,

We have a Portal Application based on WebDynpro Java. The model being used is BAPI's written in SAP HR.

There is another Portal Application based on J2EE. (Non SAP) The requirement is to use the same BAPI's to pass the data to the J2EE screens.

SAP XI needs to be used to create the SAP R/3-J2EE interfaces. Could some one advise me how to proceed on this scenario? Which Adapter needs to be used in this case?

Thanks & Regards,

Hi,

one option can be:

<i>SAP XI needs to be used to create the SAP R/3-J2EE interfaces. Could some one advise me how to proceed on this scenario? Which Adapter needs to be used in this case?</i>

SAP R/3SAP XI-J2EE application

Here if you are using BAPI from R/3 then you can use RFC adapter between SAP R/3 and SAP XI.

For SAP XI and J2EE application you can use Java proxies.

Here is how you write your Java proxy:

If yout J2EE application isn't on SAP WAS you cannot use proxy.

I think in your case SAP XI is redundant. You can use Jco connector and call BAPI directly as WebDynpro. developing will be faster and cheaper.

Hi Shobhit

You can use soap adapter , exposing your interface as web service.

and than you can use that web service in your portal.

hi,

depends how your j2ee application can connect

you can expose the BAPI via web service (SOAP) on XI

and then you're application could consume this web service

for example

but first you need to find out if your j2ee app can use

web services...

Hi Michal,

Thanks for your advise. I just needed a lead and I'll follow yours!!! Will get in touch with you once I start the implementation. Right now I am doing the WebDynpro development.

Thanks mitesh, vijaya, and sergey.
