Process theProcess = null;

BufferedReader inStream = null;

System.out.println("CallHelloPgm.main() invoked");

// call the Hello class

try

{

theProcess = Runtime.getRuntime().exec("java com.ibm.as400.system.Hello");

}

catch(IOException e)

{

System.err.println("Error on exec() method");

e.printStackTrace();

}

// read from the called program's standard output stream

try

{

inStream = new BufferedReader(

new InputStreamReader( theProcess.getInputStream() ));

System.out.println(inStream.readLine());

}

Hi,

If you want to create object use as follows

public class Myjava{

static public void main(String args[])

{

Mytest test = new Mytest();

}

}
