I just uploaded my JApplet in my webserver. And accessed using IE browser, I have a text file in the server and while the applet is trying to read am getting below exception. After that I change the file permission to 777(all read write and execute) but still am getting the same exception. Please assist me. access denied ( al3.txt read)

If the file is on the server, then you can't use FileReader or FileInputStream to read it. Any of those classes will access the client-side file system, which is off limits to applets.

See the "Hello Server File" example in for how applets can read files on the server.
