Lisp filepath issues when running application directly from jar file

[Hamda Binte Ajmal]

Hi Mark,
I tried option one, using code
            File jarFile = new
File(codeSource.getLocation().toURI().getPath());
            String jarDir = jarFile.getParentFile().getPath();
            String pathname =  jarDir + "/JavaApplication17.jar!" +
"/aima/quicklisp/setup.lisp";
            JavaApplication17 d = new JavaApplication17();
            d.Setup();
            String str = "(load \"jar:file:/" + pathname + "\")";
            str = str.replace("\\", "/");
            d.execute(str);

It gives this error "Cant ensure directory"
