embedding policy file in a jar file

I wish to deploy an applet on a web browser through a html code. The applet requires a policy file to deployed successfully. Currently, I can deploy the applet through the command line as following:

java -J-Djava.security.policy= mypolicy.policy AppletDeployment.html

how can I add the policy file in a jar file and thereafter how do I deploy the applet?

That's not possible. That would amount to the applet setting its own security policy - not something that's allowed. The alternative is to sign the applet; see HowCanAnAppletReadFilesOnTheLocalFileSystem for details.

Thank you so much for the reply. I have already gone through the link you have provided but it hardly helped. I am new to signing applets and so could not decipher many of the things. As far as the inclusion of policy file in the jar file is concerned, can please clarify your point elaborately. I found a link :policy file in a jar which does throw light on it but not elaborately.

There's nothing to elaborate - it doesn't work, whatever that page you linked to may say (the approach described on that page is not applicable to applets).

If you have specific questions about signing, tell us what, exactly, you did or did not understand, and we'll try to help you get going.
