I am trying to write a method to do a file copy command on WindowsNT,
using the following code:

  public static void copyAfile( String src_path, String dsn_path )
  {
    String copyCmd[] = {"copy",src_path,dsn_path };      
    Process copyProcess = null;      
    try {           
          copyProcess = Runtime.getRuntime().exec( copyCmd
);                      
          if ( copyProcess == null ) { 
               System.out.println("copyAfile FAILED: "+src_path+" to
"+dsn_path);            
             }          
        }        
    catch ( Exception e ) {             
             System.out.println("Error Msg: "+e);          
    }  
  }

I get an Error No.2 when this executes, What is Error No.2 and How do I
find doc's on runtime errors?  Thanks in Advance  Matt
