Regarding RFC Communication from SAP R/3 to SAP J2EE Engine 6.40

[Former Member]

Hello,

We have an application deployed in SAP J2EE engine 6.20. From SAP R3 (SAP R/3 version is 6.4C), We are communicating to the application deployed in SAP J2EE Engine 6.20 using RFC protocol. EJB module (Deployed in SAP J2EE Engine 6.20) which is being invoked from a Function Module using RFC protocol has the same name as the Function Module name. We were able to communicate to SAP J2EE Engine 6.20 this way.

Currently, I have deployed the same application in SAP J2EE Engine 6.40. I have followed the same procedure which i have used while depolying and working with SAP J2EE Engine 6.20. But, it is not working, and i was not able to communicate to SAP J2EE 6.40, the same way i did in SAP J2EE Engine 6.20.

Please let me know whether the procedure for communicating to SAP J2EE Engine 6.40 has changed in comparison with SAP J2EE Engine 6.20.

Also,Any pointers regarding RFC and JCO implementation in SAP J2EE Engine 6.40 willl be helpful.

Thank you.

Regards,

Hi Gerhard,

If you go to SM59 and try the test connection option for the RFC connection to J2EE Engine what error you are getting ?

Also Please let me know whether is there any Operating Differences between WAS 6.20 and WAS 6.40, for JCO/RFC based Communication( ie Comunicating with WAS 6.40 from SAP r/3 using RFC Protocol). Any materials and Information on how to work on SAP J2EE Engine 6.4 will also be very helpful.

Thank you.
