Self Signed Applet Can it access Local File Systems
Hi I have created a Self Signed Applet , but not able to access local files 开发者_JS百科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.
The below code is use to Add a Bouncy Castle Jar, the same way you can use it for accessing the file. AccessController java api is used.
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 "";
}
});
