Hi I have created a Self Signed Applet , but not able to access local files system .What have i to do ?
A:
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.

A:
// The below code is show for Adding a Bouncy Castle Jar , same way you can use it for acessing the file . AccessController java api is used and shown below ...
AccessController.doPrivileged(new PrivilegedAction() {
public Object run() {
try{
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); // Here you can write the code for File Accesss
}catch (Exception e) {
return "";
}
return "";
}
});
