Opening a file in JSP

Question

hi there,
How can i open a file, for example, a text file in JSP? Although i can do this if i place the file in a certain folder, i want to be able to open the file at any directory. Is it possible to do this?

yeep.. since Jsp is essentially a servlet and running on the server you can open anything you want...
in your <%page%> tag you'll have to add import="java.io.*" and then use a FileInputStream or your favorite method of reading the file in and use out.print to display the text of it... kinda similar to:
<%page import="java.io.*" content-type="text/plain"%>
<%
   FileInputStream tis=new FileInputStream("c:\windows\comsetup.log");
   byte[] da=new byte[8192];
   int len=tis.read(da);
   while(len!=-1) {
      out.write(da,0,len);
      out.flush();
      len=tis.read(da);
%>that'd do it.... you can change how the browser "reacts" by changing the content-type at the top...
