Невозможно построить сессионную фабрику в методе init для сервлета

Question

Я пытаюсь использовать спящий режим с сервлетом. поскольку SessionFactory потребовалось много времени для инициализации, я решил построить фабрику сеансов в методе init. ниже мой код сервлета.

public void init()throws ServletException 
{ 
    factory = new Configuration().configure().buildSessionFactory(); 

} 

, но я получаю ошибку следующим образом.

что это за исключение.

SEVERE: Servlet /school threw load() exception 
java.lang.SecurityException: Restricted class org.apache.catalina.servlets.CGIServlet 

Я изменил кот и попытался же я получил ниже за исключением

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). 
log4j:WARN Please initialize the log4j system properly. 

ниже мой файл hibernate.cfg.xml

<hibernate-configuration> 
<session-factory> 
<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property> 
<property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property> 
<property name="hibernate.connection.url">jdbc:oracle:thin:@ip:port:sid</property> 
<property name="hibernate.connection.username">uname</property>

<mapping resource="com/enext/edu/school/attendance/entity/EmployeeSignin.hbm.xml"/> 
</session-factory> 
</hibernate-configuration> 

, как я могу решить эту проблему?

Answer 1

кажется какой-то баночку missing..dom4j-1.5.2.jar, как получить у Caused by: java.lang.ClassNotFoundException: org.dom4j.DocumentException

Answer 2

Кажется, вам не хватает с dom4j баночки, пожалуйста, убедитесь, что у вас есть эти dependacy

<dependency> 
     <groupId>dom4j</groupId> 
     <artifactId>dom4j</artifactId> 
     <version><version></version> 
    </dependency>
