Encryption bởi jasypt

Question

import org.jasypt.util.password.*; 
public class encrypt 
{ 
private static BasicPasswordEncryptor passenc; 
public encrypt() 
{ 
    passenc=new BasicPasswordEncryptor(); 
} 
public static void useradd() 
{ 
     System.out.println("IN Useradd"); 
} 

khi tôi gọi useradd() từ một tập tin JSF tôi nhận được lỗi sau

Hãy cho tôi biết tại sao điều này đang xảy ra.

Trông giống như vấn đề triển khai - bạn có thể chỉ cần tệp jar jasypt trong thư mục lib cho webapp của bạn.
