Logon Group JCO Connection

Hi all,

I've a similar post to it, but none have solved my problem.

I've installed the ABAP 7.0 and i've a NetWeaver 2004S SP9.

I've created a Technical System to my ABAP server, when i test my JCo Connection i'm getting the following message :

-


com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=toddy GROUP=PUBLIC R3NAME=NSP MSSERV=sapmsNSP PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR Group PUBLIC not found TIME Tue Nov 27 08:00:51 2007 RELEASE 700 COMPONENT LG VERSION 5 RC -6 MODULE lgxx.c LINE 4288 DETAIL LgIGroupX COUNTER 3

Its says that group PUBLIC doesn't exists, but if i call the SMLG Transaction, i've get

Logon Group Instance Status

PUBLIC toddy_NSP_00 green

SPACE toddy_NSP_00 green

At Change Assignment :

Assignment-dependent

PUBLIC

toddy_NSP_00

IP address : 127.0.0.1 (I'm local)

Group Dependent

PUBLIC

Ext. RFC-enabled (Checked)

Instance-dependent

toddy_NSP_00

Response Time 60 ms

User 1

If i click on Test i'm getting the following error :

Internal error (SIMULATION:INACTIVE_SERVER)

Could it be the cause of my JCO don't found the LOGON GROUP?

To Application Data i can use the option to Single Server, but it isn't possible to Dicitionary Meta Data.

I've saw ate this forum about the transaction RZ70, it has some information that can be useful to identify the problem?

best regards
