The error is self explanatory. It's just not finding the file. Post the code you are using to access the file.

public class GetPageServer extends HttpServlet
{
protected void doGet(HttpServletRequest req, HttpServletResponse res)throws ServletException, IOException
{
BufferedReader textreader = new BufferedReader(new FileReader(textfile));
FileOutputStream exstufile = new FileOutputStream(new File("STU.txt"));

Because a servlet app can be deployed from either a file system structure or a war file, there is no guarantee that your file will exist on the systems hard drive as a 'file'.

The ServletContext.getResource and ServletContext.getResourceAsStream methods are provided for just this reason. If you use one of these methods, you will be able to refer to your file, relative to the context root of the app.

"Ullas V M",

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!
