Hi Juan,

Go to <Localdrive>:/windows/system32/drivers/etc/services.

Open the services notepad and add the message server name <b>sapms<SID> 3600/tcp</b> in the notepad.

Give this as i have given.Replace the SID with yours.

Try restarting the cluster. This will solve ur problem.

Hope it helps,

Nagarajan,

Thanks for your help. I changed the message service as you tell me, however I have other mistake :

I am attaching the JAVA source code, the message error and the line that I chance in the service. I try with 3600 first and then I change to 3300.

• Source Code *******

public static final String SAP_CLIENT = "150";

public static final String USER_ID = "CORGXXX";

public static final String PSWD = "XXXXXX";

public static final String LANGUAGE = "ES";

public static final String APP_SERVER_HOST = "192.168.1.132";

public static final String SAP_ROUTER = "200.106.139.84";

public static final String SYS_NUMBER = "00";

public void conexion3() {

String IP = "/H/" + SAP_ROUTER + "/W/sapprracc/H/" + APP_SERVER_HOST;

try {

JCO.Client conn = JCO.createClient(SAP_CLIENT,USER_ID,PSWD,LANGUAGE,IP,SYS_NUMBER);

System.out.println("gonna connect ...");

conn.connect();

System.out.println("successfully connected:\n" + conn.getAttributes());

conn.disconnect();

} catch (Throwable e) {

System.out.println(e.getMessage());;

System.exit(1);

}

}

*error compiling the source**

Hi Juan,

Welcome to SDN!!

"ERROR timeout occured" indicates that your logon request didnt make it to the SAP server..

Can u skip the router and connect directly to the server?? Try whether that works..

If yes,

then the problem is with routing..

Is your request routed to the server is to checked..

These are network issues and nothin pertaining to your code..
