Hi All,
I am developing FlightList Application.
I am getting the following exception. I think this is something related to Message Server Port.
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=ndcderp03 GROUP=SPACE R3NAME=DS8 MSSERV=sapmsDS8 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner '155.237.208.50:sapmsDS8' not reached TIME Thu Mar 22 12:05:18 2007 RELEASE 700 COMPONENT NI (network interface) VERSION 38 RC -10 MODULE nixxi.cpp LINE 2764 DETAIL NiPConnect2 SYSTEM CALL connect ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 2
Please let me know what should I do to resolve this.
Regards
Nikhil Bansal
Nikhil,
Try this also,
If you are on Windows go to C:\WINDOWS\system32\drivers\etc and edit the host file. Place a line in there that reads
xxx.xxx.xxx mycomputer mycomputer.domain.com
where xxx.xxx.xxx is the IP of your machine and mycomputer.domain.com is the FQDN of your machine.

Hi Nikhil,
Please Check the following:
1)From the server are u able to ping R/3 system?
2)Did u create the R/3 system in SLD?
3)Does an entry for this R/3 system exist in host file correctly?

Hi Nikhil Bansal,
If your OS is Windows, then make sure that the entry
sapms<R3 SID> 36<instance number>/TCP
is in your 'services' file
the 'services' file is located under:
c:\windows\system32\drivers\etc
I don't know the location of the file in OS other than Windows...

hi,
entry in service file should solve that , just wait for sometime or
Check out the logon group you have mentioned is it a PUBLIC?
Sometimes R/3 system runs on very protected server and they don't allow adding local J2ee server address in the service file on the server. Check out this too.

hi,
Once you created the Public group in R/3 system ideally it should work.
Try restarting your server once and check. Check for its status (green).
I guess you are using SPACE as group, and it does not exist, check this out using SMLG transaction in r/3. what information do u find over there?
regards,
abhijeet
