JCo Destination test failed

Dear experts,

I am trying to integrate the java webdynpro applications in the portal. After creating the JCO , I tried to test it but I was getting the following error:

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=dqr3imcom5702 GROUP=PUBLIC R3NAME=DR3 MSSERV=sapmsDR3 PCS=1 ERROR hostname 'dqr3imcom5702' unknown TIME Fri Jun 3 04:43:29 2011 RELEASE 700 COMPONENT NI (network interface) VERSION 38 RC -2 MODULE niuxi.c LINE 1529 DETAIL NiPGetHostByName2: hostname 'dqr3imcom5702' not found SYSTEM CALL gethostbyname_r COUNTER 2

I have created the corresponding entries in the host and services file for the hostname :" dqr3imcom5702" and message server: "sapmsDR3".

Is there any thing else which is to be done?

Also the following error can be seen when running the webdynpro application:

Caused by: com.sap.dictionary.runtime.DdException: failed to create provider: Connect to message server host failed
