I have a Web Dynpro application (an Employee Lookup App) deployed on the EP 7 portal. I have created the relevant Jco Destinations and these show up as "green" in the WebDynPro Content Administrator. I hence assume these work.
However, when I run the app it gives the following error in the browser:
Error Snippet:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=socw3s1er15 GROUP=PUBLIC R3NAME=HFD MSSERV=sapmsHFD PCS=1 ERROR service 'sapmsHFD' unknown TIME Tue May 23 20:15:16 2006 RELEASE 700 COMPONENT NI (network interface) VERSION 38 RC -3 MODULE ninti.c LINE 530 DETAIL NiPGetServByName2: service 'sapmsHFD' not found SYSTEM CALL getservbyname_r COUNTER 1
Jco Destinations used are tested successfully in the Web Dynpro content administrator
(WD_EMPLOYEE_MODELDATA_DEST, WD_EMPLOYEE_METADATA_DEST)
Is there something else that needs to be configured? The error indicates that the app is unable to connect to the backend system(socw3s1er15).
I would really appreciate it if you could take a look at error and suggest a possible resolution.
