Next, the form must be 

printed

 or 

saved

 into a file so that the tagged values remain. For the Postscript 

example, a generic Postscript printer driver is used. Such driver is best obtained from Adobe (

Adobe 

Universal Postscript Windows Driver

). The driver is available for several languages. The direct link for 

an English driver is:

When you have created a form that is used in printing, print the form 

into a file

 using the installed Universal 

Postscript driver. The file should be placed in the same directory as your application's JSP files are. 

Sometimes the tags that are inserted in the Postscript file are 

not

 intact, so you may have to edit the 

Postscript file by hand afterwards. 

9.3.2  Streaming a Postscript form from a www server 

The easiest way is to insert live data into the Postscript form is to create a JSP file that does this. Followed 

is a JSP listing of such procedure. The listing also streams the resulting Postscript file back to the client. 

<% 

  response.reset(); 

  response.setContentType("application/postscript"); 

  response.setHeader("Content Disposition","inline; file=form.ps"); 

/* Read the PostScript file into a buffer */ 

  java.io.FileReader _reader = new 

java.io.FileReader(application.getRealPath("form.ps")); 

  java.io.BufferedReader reader = new java.io.BufferedReader(_reader); 

  java.lang.StringBuffer buffer = new java.lang.StringBuffer(); 

  int c = 0; 

  while((c = reader.read()) !=  1) { 

   buffer.append((char)c); 

  } 

/* Get the current date in a simple format. */ 

  java.text.DateFormat format = java.text.DateFormat.getDateInstance(); 

  String today = format.format(new java.util.Date(System.currentTimeMillis())); 

/* Use an utility function to insert the live values */ 

xfij.util.FormUtil.formatPS(buffer, 

   new String[] { "LABTEST", "NAME OF THE TEST", 

"INUSE","DATE","PERSON","LENGTH",  TODAY }, 

   new String[] { laboratoriotutkimusBean.getAbbreviation(), 

laboratoriotutkimusBean.getName() 

    , laboratoriotutkimusBean.getInuse(), laboratoriotutkimusBean.getDate() 

    , laboratoriotutkimusBean.getPerson(), laboratoriotutkimusBean.getLength(), 

today}); 

/* Stream the response to client browser */ 

  java.io.OutputStreamWriter writer = new 

java.io.OutputStreamWriter(response.getOutputStream()); 

  writer.write(buffer.toString()); 

  writer.flush(); 

  writer.close(); 

  reader.close(); 

  response.flushBuffer();
