Hi,

Could you please check your R3 paremeters and try to see are you able to access the R3. i think the parameter details you have given for the R3 at the time for JCO configuration may be having problem.

Check this handy wiki on SDN:

http://wiki.sdn.sap.com/wiki/display/EP/TroubleshootingSAPJavaConnector%28JCo%29

(102) RFC_ERROR_COMMUNICATION -- probably you could check if an entry is added for the SAP System Messaging Service Port

in the services file of portal server (Refer above wiki).
