Answer 1

Within your <jre location>\lib\security\java.policy try adding:

grant { permission java.security.AllPermission; };

And see if it allows you. If so, you will have to add more granular permissions.

See:

Java 8 Documentation for java.policy files

and

Answer 2

Just document it here on Windows you need to escape the \ character:

"e:\\directory\\-"

Answer 3

Although it is not recommended, but if you really want to let your web application access a folder outside its deployment directory. You need to add following permission in java.policy file (path is as in the reply of Petey B)

permission java.io.FilePermission "your folder path", "write"

In your case it would be

permission java.io.FilePermission "S:/PDSPopulatingProgram/-", "write"

Here /- means any files or sub-folders inside this folder.

Warning: But by doing this, you are inviting some security risk.
