To perform file I/O on the local machine, the applet needs to be signed (see HowCanAnAppletReadFilesOnTheLocalFileSystem). The file in question needs to be accessible to the applet, so it must be in the applet jar, or some other publicly accessible directory on the web server.

The policy file can't be changed programmatically; you need to do it manually.

Dear Sir,


Is there any other option to give permission to applet.

The only other way is to sign it, as that page explains.
