Hi I have created a Self Signed Applet , but not able to access local files system .What have i to do ?
you need to wrap your IO code inside PrivilegedAction.
Generally, you need to sign your applet with your test certificate, the user will see a warning and will have to accept the certificate when it loads the applet.
then you need to wrap your code inside a PriviligedAction. see this for some examples.
