Question

我正在使用Hibernate开发一个JSF webapp。我测试了一个主类，我可以插入数据库，但我不能将我的webapp部署到Glassfish。它总是出现HTTP 500错误。这是我的代码：

faces-config：

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"

 </managed-bean>
 <navigation-rule>
  <from-view-id>/EditTimesheet.jsp</from-view-id>

</faces-config>

web.xml：

EditTimesheet.jsp：

        <h:inputHidden id="id" value="#{timesheetBean.currentTimesheet.id}" />
        <h:panelGrid columns="2" border="1">
            <h:inputText value="#{timesheetBean.currentTimesheet.action}">
            </h:inputText>
            <h:outputText value="heure:" />
            <h:inputText value="#{timesheetBean.currentTimesheet.heure}">

            <h:outputText value="date:" />
            <h:inputText value="#{timesheetBean.currentTimesheet.date}">
            </h:inputText>

</h:panelGrid>
        <h:commandButton value="Save" action="listeDepartements" actionListener="#{timesheetBean.saveTimesheet}" />
        <h:commandButton value="Annuler" action="listeTimesheet"/>
    </h:form>
    </f:view>
</body>
</html>

该例外是：

javax.servlet.ServletException: net/sf/hibernate/HibernateException

 root cause: java.lang.NoClassDefFoundError: net/sf/hibernate/HibernateException

这是如何引起的？如何解决？

Answer 1

看来您正在使用Hibernate，但没有内置于战争中的Hibernate jar和依赖项。确保所需的所有依赖项都构建在战争中的WEB-INF / lib目录中。

此过程取决于您构建Web应用程序的方式。

java.lang.NoClassDefFoundError：net / sf / hibernate / HibernateException
