Reading File from outside the WEBROOT

[sk mehrotra]

Hi,
I am trying to open a text file from jsp page.
when the file is in the web root, then the file is open, but when i copy the file to some other directory like D drive, then its showing error: "The requested URL /servlets/oracle.jsp.JspServlet was not found on this server". This error shows that its not finding the file.

The Code i am using :
<%@page contentType="text/html" import="java.io.*" %>
<%
String path="E://REPORT//test.txt";
out.println(path);
response.setContentType("text");
response.setHeader("content-disposition","inline;filename="+path);
String temp=request.getRealPath(path);
//out.println(temp);
FileInputStream fin;
try
{
fin = new FileInputStream (temp);
out.println( new DataInputStream(fin).readLine() );
fin.close();
}
catch (IOException e)
{
out.println ("Unable to read from file" +e);
System.exit(-1);
}
%>

Thanks for your Help

Regards

There are quite a few things that are sort of wrong in that code. Please study some resources on how to handle exceptions, servlet/jsp environment, MVC architecture etc..

Anyhow -
Is the second slash after REPORT ('//') a mistake?
Do not use System.exit() in a JSP running in a servlet container!!!
At the very least, wrap the IOException in a RuntimeException and throw it again. At least, that will show you why it is failing.

You should not use request.getRealPath() with absolute path (E://REPORT//test.txt) because it is already real full path.
You use request.getRealPath only if you have file relative to your web application folder. By the way, this method is deprecates and you should use ServletContext.getRealPath() or application.getRealPath() from your JSP.
