??????? Properties prop = new Properties();
??????? File file = new File(System.getProperty("user.dir")
???????????????????????????????? + "/EMweb/WEB-INF/admininfo.properties");
??????? prop.setProperty("userName", String.valueOf(cUserName));
??????? prop.setProperty("userPassWord", String.valueOf(cUserPassWord));
??????? try {
??????????? OutputStream fos = new FileOutputStream(file);
??????????? prop.store(fos, "admininfo.properties");
??????????? fos.close();
??????? } catch (FileNotFoundException ex) {
??????????? ex.printStackTrace();
??????? } catch (IOException ex) {
??????????? ex.printStackTrace();
??????? }
