我正在尝试使用Tomcat和eclipse运行hibernate JNDI示例应用程序。当我尝试运行该程序时，我收到以下错误。我也是JNDI的新手。

我一直试图找到问题的答案但是，我找不到合适的答案。我在eclipse和Mysql中使用Tomcat服务器，数据库名称为＃34; webapp＆＃34;。
另外 - 如何让index.html连接到＆＃34; GetEmployeeByID.java＆＃34; servlet的。我是否需要在web.xml中编写servlet映射。？
答案 0 :(得分：0)
正如Seelenvirtuose在评论中所说，
的hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>

<强>＆LT; property name =＆＃34; hibernate.connection.datasource＆＃34; ＆GT;的java：comp / env的/ JDBC / WEBAPPLICATION＆LT; / property＆gt;

<强>＆LT; res-ref-name＆gt; java：comp / env / jdbc / webapp＆lt; / res-ref-name＆gt;
指向不同的地方，它们必须是相同的。
<强>＆LT; property name =＆＃34; hibernate.connection.datasource＆＃34; ＆GT;的java：comp / env的/ JDBC / WEBAPPLICATION＆LT; / property＆gt;
这个必须在你的情况下：
<强>＆LT; property name =＆＃34; hibernate.connection.datasource＆＃34; ＆GT;的java：comp / env的/ JDBC / web应用＆LT; / property＆gt;
