Question

我正在制作一个项目，其中我使用servlet并通过它调用EJB。

包名称为kotisoft
bean名称是entrybean
接口名称entrybeanLocal

我的servlet代码是：

public class reportthis extends HttpServlet {

  protected void processRequest(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException {
    response.setContentType("text/html;charset=UTF-8");
    PrintWriter out = response.getWriter();
    try {
    // Context jndiContext = new javax.naming.InitialContext();
    // InitialContext ic=new InitialContext();
    // entrybean = (entrybean)ic.lookup("java:global/KotiSoft-ejb/entrybean");

    /* TODO output your page here. You may use following sample code. */

    String jindiName = entrybean.class.getName();
    InitialContext ctx = new InitialContext();
    entrybean entrybean;
    entrybean = (entrybean) ctx.lookup(jindiName);

    String name,emailid,model,problem;
    name=request.getParameter("Name");
    emailid=request.getParameter("Emailid");
    model=request.getParameter("Model");
    problem=request.getParameter("Problem");
    Ticket ticket=new Ticket(); 
    ticket.setEmailid(emailid);
    ticket.setModel(model);
    ticket.setName(name);
    ticket.setProblem(problem);
    ***entrybean.addTicket(ticket);***...

加星标的代码是抛出异常的地方。

Glassfish服务器日志是：

我已完成所有导入，我的EJB工作正常，服务器运行良好。我还将类文件夹添加到我的WAR中但没有用。

我明白了！

我添加了玻璃鱼部署描述符

并且我添加了ejb n给它一个jndi名称

我的servlet shud中的入口bean声明也是entrybeanLocal，而不仅仅是入口bean

java.lang.NoClassDefFoundError：kotisoft / entrybean
