should we use main method in JCO

1/

Should we use main method in JCO.. Connections does not seem to be simple java programes... so why should we use them??? just for the sake of running the programme?

2/ And the below mentiond programme.. there is nothing called Connect1. Still the that class is created ..

do not you thik it has to be <b>TutorialConnect1</b> object and constructor,

import com.sap.mw.jco.*;

public class TutorialConnect1 extends Object {

JCO.Client mConnection;

public Connect1() {

try {

// Change the logon information to your own system/user

mConnection =

JCO.createClient("001", // SAP client

"<userid>", // userid

"****", // password

null, // language

"<hostname>", // application server host name

"00"); // system number

mConnection.connect();

System.out.println(mConnection.getAttributes());

mConnection.disconnect();

}

catch (Exception ex) {

ex.printStackTrace();

System.exit(1);

}

}

public static void main (String args[]) {

Connect1 app = new Connect1();

}

}
