Message:

java getRunTime.exec( ) function

Posted by Jane on May 02, 2001 at 5:38 PM

Hi everyone,

I am trying to use java Runtime function to open vi editor, I used the
following program:

import java.io.*;

public class viTest
{
public static void main(String args[])
{
Process theProcess = null;
System.out.println("viTest.main() invoked");

try
{
theProcess = Runtime.getRuntime().exec("vi");
}
catch(IOException e)
{
System.err.println("Error on exec() method");
e.printStackTrace();
}
} // end method
} // end class

It doesn't work. But if I replace "vi" with "emacs", it works. Does
anyone knows what's the problem? Thanks
