Error in JCo Connection creation

Question

Hi All,
When I create a JCo connection on my local J2EE it fails with the error enclosed as below:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM  TYPE=B MSHOST=frces4066 GROUP=PUBLIC R3NAME=AM1 MSSERV=sapmsAM1 PCS=1 ERROR       partner not reached (host frces4066, service sapmsAM1) TIME        Mon Apr 03 18:44:33 2006 RELEASE     640 COMPONENT   NI (network interface) VERSION     37 RC          -10 MODULE      nixxi_r.cpp LINE        8596 DETAIL      NiPConnect2 SYSTEM CALL SiPeekPendConn ERRNO       10061 ERRNO TEXT  WSAECONNREFUSED: Connection refused COUNTER     1 
When I try and ping the JCo the error is as enclosed below:
Failed to ping JCo destination WD_COMMITMENT_MODELDATA_DEST
I have maintained the enteries in hosts file as well as the services file and when I telnet the server on port 36XX where XX is the system number of the system I create the JCo for it connects successfully.
When I test the CIM test for the SLD that connects successfully.
Where and why is the JCo failing after creation?
Can someone throw some light on this error.
Thanks in advance for all your help.
Best regards,
Divya

Hi All,
Anyone can help? I got the same problem. It seems that the PUBLIC group in NSP ABAP system can't not be accessed.
Here is my system landscape:
- I have installed the Java and ABAP in the same host
- My ABAP system is NW2004sSneakPreviewABAP, Java is SAPNetWeaver04_SP16Preview
1) I set up SLD successfully (import CIM, run <b>RZ70</b>, the ABAP system shown up in the Technical Landscape in SLD
2) I created JCO destination with Load Balancing but it failed to ping and to test
3) I already define the group 'PUBLIC' in tx <b>SMLG</b> but from SAPGUI I can't add the group. I got the error message "<b>Message Sever could not find any group</b>".
4) The PUBLIC group does not show if I run the program <b>'lgtst'</b>.
Test lgtst:
===========
c:\usr\sap\NSP\SYS\exe\nuc\NTI386><b>lgtst.exe -H hpxp2 -S sapmsNSP</b>using trcfile: dev_lg
list of reachable application servers
<b>[hpxp2_NSP_00] [hpxp2] [10.10.0.10] [sapdp00] [3200] [DIA UPD ENQ BTC SPO ICM ]</b>
c:\usr\sap\NSP\SYS\exe\nuc\NTI386>lgtst.exe -H hpxp2 -S 3600
using trcfile: dev_lg
list of reachable application servers
[hpxp2_NSP_00] [hpxp2] [10.10.0.10] [sapdp00] [3200] [DIA UPD ENQ BTC SPO ICM ]
