Hi all,
I tried several time to create a RFC WebDynpro aaplication. But when I try to connect to the R/3 system via JCo I always get an error!
I created an ABAP System within the SLD. I created a JCo accessing the R/3 application server directly - This connection is working fine.
Then I created a JCo connection for reading out the meta-data. This JCo looks up the message server of the R/3. This connection does not work! I always get following error when testing the connection the first time after creating:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=mcgee GROUP=PUBLIC R3NAME=DH1 MSSERV=sapmsDH1 PCS=1 ERROR service 'sapmsDH1' unknown TIME Fri Sep 08 11:42:56 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 MODULE ninti.c LINE 505 DETAIL NiPGetServByName2: service 'sapmsDH1' not found SYSTEM CALL getservbyname_r COUNTER 1
When I test the connection after that I get following error:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=mcgee GROUP=PUBLIC R3NAME=DH1 MSSERV=sapmsDH1 PCS=1 ERROR service '?' unknown TIME Fri Sep 08 11:44:33 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1
I specified the server and the service in my etc/hosts and etc/services files
I posted the problem already within thread:
But I got no helpful answer yet!
Can someone help me
regards
René
