        LicenseGenerator.init();

        KeyStore ks = KeyStore.getInstance("AKS", AkSigProv.PROV_NAME);

        String x = LicenseGenerator.generateLicense(pr, snlist, props, cert, pk);
        try (FileOutputStream fos = new FileOutputStream(outFile)) {
            fos.write(x.getBytes());
            }
        }
    
    
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        try {
            processRequest(request, response);
        } catch (Exception ex) {
            Logger.getLogger(generator.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
   
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        try {
            processRequest(request, response);
        } catch (Exception ex) {
            Logger.getLogger(generator.class.getName()).log(Level.SEVERE, null, ex);

    }

  
    @Override
    public String getServletInfo() {
        return "Short description";
    }// </editor-fold>
}

I accept data from html and take the key from here (C:/keys/lic/lic.aks), then generate and write to a file, which should be located at (C:/temp/asd.lic).
I click the button but it doesn't create the file. What could be the problem?
