JCO COnnections - Problem

[Former Member]

Hi,

I am working on CE 711 EHp1 . i want to connect tocrm server , for that i have done the following config:

1 . Created a Technical System .

2 . Created a JCO destination .

when i try to test , i am getting the following exception

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 ERROR service 'sapmsC5R' unknown TIME Tue Feb 24 19:15:10 2009 RELEASE 711 COMPONENT NI (network interface) VERSION 39 RC -3 MODULE nixxhsl.cpp LINE 643 DETAIL NiHsLGetServNo: service name cached as unknown COUNTER 1

what are the other configurations , which i need to do :

what are the entries which i have make in the hast file?

is it mandatory to create a JCO destination to create adaptive RFC model in web dynpro?

Thanks and Regards

Hi,

Create an entry in the C:\WINDOWS\system32\drivers\etc\services file as follows on your server

Ex sapmsB11 3600/tcp

In your case it would be

sapmsC5R 3600/tcp

Hi,

Format is

<service name> <port number>/<protocol>

Following is details

<service name> Service name is ideally sapms<SID>

<port number> default is 3600

<protocol> tcp

Hope this helps to find it. If changes are not reflected try restarting your system.

Hi Ayyaparaj,

I followed ur article "Creating Technical System " . I have already created Technical System andd JCO . if there any other configurations should be done.

for using the RFC in web dynpro java , is it mandatory to create a JCO destination?

Hi Ayyaparaj,

Thanks for ur reply.

I have created the Techincal system and RFC destinations but when i ping , it is showing a Error message -- "Failed to ping Jco Destination " ? what could be the problem.

one more thing is when i import a RFC Model from web dynpro java, it shows me available model. for eg , i can find the filight model from the SAP Backend System.

but the problem is Jco Destination , it shows error , when i do the test and ping opertion.

In ur article , u have created SLDData Supplier and SLD Supplier, why it is created? what is use of this destinations ?

Thanks and regards
