关于Hibernate出错的问题，请教高手……谢谢了
部分代码如下：
Cservlet.java

Java code

import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;import com.mmc.model.CBean;public class Cservlet extends HttpServlet {    public void doGet(HttpServletRequest request, HttpServletResponse response)            throws ServletException, IOException {                response.setContentType("text/html");        PrintWriter out = response.getWriter();                CBean c = new CBean();                System.out.println("在servelet中");        int id = Integer.parseInt(request.getParameter("id"));        String name = request.getParameter("name");        String title = request.getParameter("title");        c.setID(id);        c.setName(name);                Configuration cfg = new Configuration();        SessionFactory sf = cfg.configure().buildSessionFactory();        Session session = sf.openSession();        session.beginTransaction();                session.saveOrUpdate(c);        session.getTransaction().commit();        session.close();        sf.close();            }    public void doPost(HttpServletRequest request, HttpServletResponse response)            throws ServletException, IOException {        doGet(request, response);    }}

CBean.hbm.xml

Java code

……<hibernate-mapping package="com.mmc.model">    <class name="CBean" table="m">         <id name="ID" column="id"> </id>            <property name="name"></property>    </class></hibernate-mapping>

hibernate.cfg.xml

XML code

<session-factory>        <!-- Database connection settings -->        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>        <property name="connection.url">jdbc:mysql://localhost/a</property>        <property name="connection.username">root</property>        <property name="connection.password">123</property>        <!-- JDBC connection pool (use the built-in) -->        <property name="connection.pool_size">1</property>        <!-- SQL dialect -->        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>        <!-- Enable Hibernate's automatic session context management -->        <property name="current_session_context_class">thread</property>        <!-- Disable the second-level cache  -->        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>        <!-- Echo all executed SQL to stdout -->        <property name="show_sql">true</property>        <property name="format_sql">true</property>        <!-- Drop and re-create the database schema on startup -->        <property name="hbm2ddl.auto">update</property>         <mapping resource="com/mmc/model/CBean.hbm.xml"/>            <!--<mapping class="com.mmc.model.DBean"/> -->    </session-factory>

运行后，出现错误如下：

走到

Java code

SessionFactory sf = cfg.configure().buildSessionFactory();

这里出错的……

请教各位高手们了，，谢谢……

[解决办法]
路过帮顶
[解决办法]
是不是缺少包了...
[解决办法]
无法创建Session工厂，在javaProject里面好着，在web里面出问题，应该是jar包冲突了。把jsp-api.jar这个jar包删除了试试看、、、
[解决办法]
构建seseionFactroy出错了，
我记得构建这个Configuration你得设置一下文件的吧？？

Java code

Configuration configuration = new Configuration();configuration=configuration.configure("hibernate.cfg.xml");configuration=configuration.addProperties(extraProperties);sessionFactory=configuration.buildSessionFactory();
[解决办法]
org.hibernate.integrator.spi.Integrator: Provider org.hibernate.envers.event.EnversIntegrator 不能找到这个包：
