Java休眠错误

Question

我想插入到我的postgresql数据库使用休眠，我挺或还没有弄清楚为什么我不断收到这个错误，我想要做的是让我的休眠创建我的数据库表和列并插入到创建的表中。所以我的第一个错误是关于失踪的jar文件，这是我已经加入到我的Hibernate库的SLF4J，但是经过我再次运行应用程序新的错误弹出所以这是我的错误：

90 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons 

Annotations 3.2.0.Final 
100 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.6.10.Final 
100 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found 
100 [main] INFO org.hibernate.cfg.Environment - Bytecode provider name : javassist 
100 [main] INFO org.hibernate.cfg.Environment - using JDK 1.4 java.sql.Timestamp handling 
150 [main] INFO org.hibernate.cfg.Configuration - configuring from resource: /hibernate.cfg.xml 
150 [main] INFO org.hibernate.cfg.Configuration - Configuration resource: /hibernate.cfg.xml 
Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found 
    at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:170) 
    at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:2176)

    at org.hibernate.cfg.Configuration.configure(Configuration.java:2137) 
    at org.hibernate_main.HibernateMain.main(HibernateMain.java:13) 

这是我的JAR文件（INT Hibernate库）：

hibernate3.jar 
antlr-2.7.6.jar 
commons-collections-3.1.jar 
dom4j-1.6.1.jar 
javassist-3.12.0.GA.jar 
jta-1.1.jar 
slf4j-api-1.6.1.jar 
hibernate-jpa-2.0-api-1.0.1.Final.jar 
postgresql-9.1-902.jdbc4 

而且我的代码： 配置（XML）

} 

我的主类：

package org.hibernate_main; 
import org.hibernate.Session;

import org.hibernate.cfg.Configuration; 
import org.user_detail.dto.UserDetail; 

public class HibernateMain { 
    public static void main(String[] args){ 
     UserDetail user = new UserDetail(); 
     user.setUserId(1); 
     user.setUserName("Jerome"); 

     SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 
     Session session = sessionFactory.openSession(); 
     session.beginTransaction(); 
     session.save(user); 
     session.getTransaction().commit(); 
    } 
} 

家伙你能告诉我这是什么错误是，如何解决这些问题，以及如何测试，如果在XML数据库连接是成功还是失败。多谢你们。

我觉得

/hibernate.cfg.xml not found 

是非常明显的。

确保它在CLASSPATH中。

您还可以指定它：

return new Configuration().configure("/path/to/hibernate.cfg.xml").buildSessionFactory(); 

在你的代码上述
