JCO Connection Error

[Former Member]

Hi,

We created a JCo connection for ECC server. We are getting the following exception when we try pinging or when we press Test.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=hsdnt24s15 GROUP=PUBLIC R3NAME=C5R MSSERV=sapmsC5R PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR service 'sapmsC5R' unknown TIME Tue Feb 24 14:54:54 2009 RELEASE 711 COMPONENT NI (network interface) VERSION 39 RC -3 MODULE nixxhsl.cpp LINE 643 DETAIL NiHsLGetServNo: service name cached as unknown COUNTER 4

Hi Sudhir,

You have to make an entry in services file.

Go to C:\WINDOWS\system32\drivers\etc open services with notepad

In the last line make this entry

sapmsC5R msgserverport/tcp (e.g. 3600/tcp)

Save and close it.

Now test in WD content manager.

Regards,

Siva
