it seems you gave parameters like you do in Java gui but for JCo it should be like this in java code,

public CallFunction() {

try {

// Logon info

mConnection = JCO.createClient("500", // SAP client

"username", // userid

"password", // password

null, // language

"server name", // application server host name

"00"); // system number

mConnection.connect();

mRepository = new JCO.Repository("ARAsoft", mConnection);

} catch (Exception ex) {

ex.printStackTrace();

System.exit(1);

}

so change your configuration file with respect to code.
