RFC_ERROR_COMMUNICATION

Hi Experts,

We are using WAS 7.00 SP11. When ever we deploy an application with out RFC function calling our application was running successfully. But I have to call BAPI in my application, for that I have created JCO Connection . After creating the JCO Connection, message displayed as ..........

<i>JCo destination 'WD_F4Model_MODELDATA_DEST' was successfully created in SLD</i>

After teting the JCO connection message displayed as ....

<i>com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=server2 GROUP=PUBLIC R3NAME=PRO MSSERV=sapmsPRO PCS=1 ERROR Group PUBLIC not found TIME Mon May 14 15:53:10 2007 RELEASE 700 COMPONENT LG VERSION 5 RC -6 MODULE lgxx.c LINE 4288 DETAIL LgIGroupX COUNTER 1 </i>

I have searched for SDN and got a response.

<i><b>I think your logon group in the backend called SPACE is pointing to localhost. So, the load balancer is telling the portal to go to localhost port 3305.</b></i>

But how where to check this logon group information, how to set this to my WAS.

My WAS is on one machine and message server ( R/3) is on another machine.

Any body help me how to solve this error..
