Hai guys,

I need your help,I am trying to execute a program which is in the local system from an applet using run = Runtime.getRuntime(), pp=run.exec("c:\program files\...\*.exe) .

But i am getting an exception from the JVM as

"java.security.AccessControlException: access denied (java.io.FilePermission C:\Programexecute)"

I had modified the java policy file as

permission java.io.FilePermission "C:/Program Files/GX/Scanner/Abby Testing.exe" ,"execute";
permission java.io.FilePermission "*" ,"execute";

Its really urgent ma enitre project is blocked.

It will be very very helpful, if some one can help me to sort this.

Solution 1

You can override the default security policy file used by the SecurityManager:

1) Create a text file (eg. applet.policy)

2) Grant all permissions to the applet by adding this to the file:

grant {
 permission java.security.AllPermission;
};

3) Run the applet with

-J-Djava.security.policy=applet.policy
