Direct Known Subclasses:

WebDAVServlet

public class FileServlet

extends javax.servlet.http.HttpServlet

This servlet serves files from the filesystem.

It accepts initial parameter named "defaultPages", which must be a comma-separated list of file names, for example "index.jsp,index.html". A default page is a page which is served if no particular file from the directory has been requested by the end user.

This servlet supports also directory indexes if the "dirIndex" initial parameter is set to true. Directory index is a HTML page with a list of subdirectories and files within the given directory. It is displayed only if no default page can be found for the given directory. If the "/icons/file.gif" file exists within the web application's root directory, the servlet will generate the index pages with the images found in the "/icons/" directory. Currently, only these image file names are recognized:

• /icons/file.gif - regular file
• /icons/foldero.gif - active folder
• /icons/folderc.gif - inactive folder

This servlet overrides the superclass' getLastModified method to check for the last modification time of the requested files.
