Hi All, We are getting the following error , when we connected the JCO connection.
Can any body guess it what is the cause of this error
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=eimkopdvs1 GROUP=PRD R3NAME=EIT MSSERV=sapmsEIT PCS=1 ERROR service '?' unknown TIME Wed Oct 18 16:10:35 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1
On the server, if you haven't done so, you need to change the services file.
Under C:\WINDOWS\system32\drivers\etc
Make an entry for the system you are trying to connect to.
For example, if the SID is ABC and the message port is 01, then the entry should look like this.
sapms<b>ABC</b> 36<b>01</b>/tcp
After you add the entry, be sure to re-boot the server and try your jCo connection again.
Regards,
Rich Heilman
