Architecture Question & Recommendations.

[Former Member]

We have a need for a Java web based application that calls into BAPIs and custom SAP function modules.

We would like to deploy the Java app on a standalone WAS 6.4 server running only the J2EE engine. Can we deploy in this way and have it make calls to our SAP ABAP applications environment running on a separate WAS 6.2 platform?

Will this work and/or can anyone suggest better alternatives? Web services eposed on the 6.2 side perhaps?

Thanks for any help or ideas.

Yep, this is possible. To allow for quick development I would advise to use Web Dynpro's as this technology has helped us to quickly and reliably create and maintain several applications already!

After some initial getting-used-to the way these Web Dynpro applications are constructed we are now able to build RFC or Web Service calling Java applications in days instead of weeks!!

Apart from the SAP-specific features, you can also do all the 'traditional' Java development you could want

Kind regards, Jurjen.

Hello Scott,

I see no handicaps using the WebAS 6.40 Java to call the SAP ABAP on WebAS 6.20. You can use Webservices also because all RFC enabled Function Modules are avaliable as a Webservice on 6.20.
