我正在运行一个带有hibernate的Web应用程序,并且遇到了这个异常.有什么帮助吗？

抛出java.lang.ClassNotFoundException:org.hibernate.HibernateException在org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714)在org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1559)在com.forum.dao.TopicDAO.findAll(TopicDAO.java:43)在com.forum.servlets.Accueil.doGet(Accueil.java:23)在javax.servlet.http.HttpServlet.service(HttpServlet.java:621)在javax.servlet.http.HttpServlet.service(HttpServlet.java:728)在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:305)在org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain的.java:210)在org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:222)在org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:123)在org.apache.catalina. authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472)at org.apache.catalina.core.StandardHostValve.invoke(StandardHostVal)ve.java:171)在org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:99)在org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:953)在org.apache.catalina .core.StandardEngineValve.invoke(StandardEngineValve.java:118)在org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:408)在org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1008 )atg.apache.coyote.AbstractProtocol $ AbstractConnectionHandler.process(AbstractProtocol.java:589)位于java.util.concurrent的org.apache.tomcat.util.net.JIoEndpoint $ SocketProcessor.run(JIoEndpoint.java:312). java.lang.Thread.run上的java.util.concurrent.ThreadPoolExecutor $ Worker.run(未知来源)中的ThreadPoolExecutor.runWorker(未知来源)(未知来源)

这是TopicDAO.findALL()

public static List<Topic> findAll() {

    Session  s = HibernateUtils.getSession(); //TopicDAO.java:43
    Transaction tx = s.beginTransaction();
    List<Topic> objects = null;

    Query q = s.createQuery("from Topic");
    objects = q.list();
    tx.commit();

    return objects;
}

而且,这是我的servlet.doGet()

public void doGet( HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
    HttpSession session = request.getSession();

    TopicDAO td = new TopicDAO();
    List<Topic> listTopics = td.findAll();

    session.setAttribute( ATT_LIST_TOPICS, listTopics );

    this.getServletContext().getRequestDispatcher( ACCUEIL ).forward( request, …

如何使用Java将pdf文件转换为word文件？

而且,它看起来像它一样容易吗？

我收到了这个错误,有人可以帮帮我吗？
