Jco Error after sso

HI all,

We have configured sso between portal  , the jco's were working fine. After configuring sso between  a new EREC system  and the existing portal sytem, the jco's keep failing.

Service and host entries are maintained in both servers,

Connection parameters are maintained properly.

but the following error occurs: the jco's point to the existing HR system,

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connection parameters: TYPE=B DEST=<Java Rfc client> MSHOST=smcides R3NAME=DEV GROUP=SPACE PCS=1 LOCATION    CPIC (TCP/IP) on local host with Unicode ERROR       partner '127.0.0.1:SAPGW00' not reached TIME        Mon Jun 02 02:24:47 2014 RELEASE     721 COMPONENT   NI (network interface) VERSION     40 RC          -10 MODULE      nixxi.cpp LINE        3285 DETAIL      NiPConnect2: 127.0.0.1:3300 SYSTEM CALL connect ERRNO       10061 ERRNO TEXT  WSAECONNREFUSED: Connection refused COUNTER     11
