I know that this is to be expected as applets generally have no access
to resources outside of the browser. After digging for the possible
solutions I found (http://java.sun.com/developer/onlineTraining/
Programming/JDCBook/appA.html) that this may actually be possible by
granting such access in the policy file.
I edited java.policy.applet file - the one which is generated and sits
in the same location as CLASS files. The modified policy file looks as
follows:
grant {
permission java.security.AllPermission; // this was generated
permission java.lang.RuntimePermission "loadLibrary.*"; // this is
added by me
}
Unfortunately, I still have the same exception. Any idea what I am
missing? Wrong policy file perhaps?
It seems very unlikely that the browser plugin will look for
the policy in the same dir as your class file.
Is there another way of granting applet with access to local DLLs? I
think signed applet was another hint but could someone guide me how to
do this?
I think you will be better off switching to Java Web Start.
