JCo connection problem

18 Views

Hi everybody,

I am trying to establish an Jco connection to R/3 server.

I have configured SLD and tested it.

Though i successfully created a new Jco connection "SAP_R3_HumanResources" for the ESS BP,

I encountered the following error when testing the Jco connection:

"com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=A ASHOST=ctsgvcsap3 SYSNR=03 GWHOST=ctsgvcsap3 GWSERV=sapgw03 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR service '?' unknown TIME Thu Dec 22 19:00:12 2005 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1"

please note: We have added ECC 5.0 components when creating the connection in SAPGUI

Thanks in advance,

Vivekanandan.V
