Problem creating a Post script file

[krishnan.1000]

Hi,

I have to create a Postscript for a project that I am working on. The file that I create can not be opened by any application. I would be grateful for any help that anyone can give.

Code:

public class PostScriptTest {
  
  public static void main(String[] args) throws IOException {
    
    File file = File.createTempFile("test", ".ps");
    OutputStream os = new FileOutputStream (file);
    os.write(createHeader().toString().getBytes());
    os.close();
  }
  
  private static String getTodaysDate() {
    Date now = new Date();
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
    return sdf.format(now);
  }
  
  private static StringBuffer createHeader() {
    StringBuffer sb = new StringBuffer();
    
    sb.append("%!PS-Adobe-2.0 EPSF-2.0\n"
            + "%%Creator: Page @VERSION@\n"
            + "%%Title: Page \n"
            + "%%CreationDate: "
            + getTodaysDate()
            + "\n"
            + "%%Origin: 0 0\n"
            + "%%BoundingBox: "
            + 0
            + " "
            + 0
            + " "
            + "\n"
            + "%%EndComments\n"
            + "%%BeginProlog\n"
            + "100 dict begin\n"
            + "/wordbreak ( ) def\n"
            + "/linebreak (\\n) def\n"
            + "/doLine {\n"
            + "% <line> <width> <height> <x> <y> doLine <width> <height> <x> <y>\n"
            + "2 copy moveto 5 -1 roll\n"

            + "          6 3 roll 2 index sub 2 copy moveto 6 3 roll\n"
            + "      } if\n"
            + "      show wordbreak show\n"
            + "  }{\n"
            + "      dup stringwidth pop currentpoint pop add 5 index 4 index " +
                  "add gt {\n"
            + "          3 1 roll 3 index sub 2 copy moveto 3 -1 roll\n"
            + "      } if\n" + "      show exit\n" + "  } ifelse\n"
