    1)啟動Tomcat服務器，打開瀏覽器，輸入http://localhost:8080/admin（其中localhost是名稱服務器或稱為主機），
    
進入管理界面的登陸頁面，這時候請輸入原來安裝時要求輸入的用戶名和密碼，登陸到管理界面，
    

    2)選擇Resources－Data sources進入配置數據源界面，選擇
    
 Data Source Actions －>選擇Create New Data Source,進入配置詳細信息界面
    
主要內容例如下：
    
JNDI Name:   ->jdbc/mysql
    
Data Source URL  ->jdbc:mysql://localhost:3306/test
    
JDBC Driver Class-> org.gjt.mm.mysql.Driver
    
3)修改\conf\Catalina\localhost目錄下建立一個xml文件,名稱為你所發布的web應用的名稱．xml,(如testpool.xml)打開添加內容如下:
    
<?xml version="1.0" encoding="UTF-8"?>
    
<Context>
    
 <Resource
    
      name="jdbc/mysql"
    
      type="javax.sql.DataSource"
    
      password="123456"
    
      driverClassName="org.gjt.mm.mysql.Driver"
    
      maxIdle="2"
    
      maxWait="50"
    
      username="root"
    
      url="jdbc:mysql://localhost:3306/test"
    
      maxActive="4"/>
    

    </Context>
    
內容同conf/server.xml中<GlobalNamingResources>
    
 <Resource
    
      name="jdbc/mysql"
    
      type="javax.sql.DataSource"
    
      password="123456"
    
      driverClassName="org.gjt.mm.mysql.Driver"
    
      maxIdle="2"
    
      maxWait="50"
    
      username="root"
    
      url="jdbc:mysql://localhost:3306/test"
    
      maxActive="4"/>
    
  </GlobalNamingResources>
    

    
少了這一步會報錯：Cannot create JDBC driver of class '' for connect URL 'null'
    
4)修改web.xml
    

    打開%TOMCAT_HOME%\conf\web.xml或yourwebapp/web-inf/web.xml,添加以下內容：
    
    <resource-ref>
    
    <description>DB Connection</description>
    
    <res-ref-name>jdbc/mysql</res-ref-name>
    
    <res-type>javax.sql.DataSource</res-type>
    
    <res-auth>Container</res-auth>
    
    </resource-ref>
    
    注意res-ref-name填寫的內容要與在上文提到的JNDI Name名稱一致。 
    
 到這里，配置工作就基本完成了!
    

    5)引用JNDI時用"java:comp/env/jdbc/mysql";
    
建立文件測試 test.jsp：
    
<%@page contentType="text/html;charset=utf-8" %>
    
<%@page import="java.sql.*" %>
    
<%@page import="javax.sql.*" %>
    
<%@page import="javax.naming.*" %>
    
<html>
    
<head>
    
<title>Tomcat連接池測試</title>
    
</head>
    
<body>
    
<%
    
  Context ctx=new InitialContext();
    
  Connection conn=null;
    
  DataSource ds=(DataSource)ctx.lookup("java:comp/env/jdbc/mysql");
    
  conn=ds.getConnection();
    
  Statement stmt=conn.createStatement(ResultSet.CONCUR_READ_ONLY,ResultSet.CONCUR_UPDATABLE);
    
  ResultSet rs=stmt.executeQuery("select * from testexample");
    
  while(rs.next()){
    
  out.println(rs.getInt(1));
    
  out.println(rs.getString(2));
    
  out.println(rs.getString(3));
    
  }
    
  out.println("數據庫操作成功！");
    
  rs.close();
    
  stmt.close();
    
  conn.close();
    
    
    
 %>
    
</body>
    
</html>

    請再檢查一下你的Tomcat版本，并確定你是否按照我的這個步驟配置的？把你的錯誤日志發給我，我幫你看一下。

    你那方法還是不行啊，我只要登錄的話，tomcat 馬上就出錯,錯誤日志如下：

    麻煩老兄看下啊，還有你“JNDI Name:   ->jdbc/mysql”這個地方一定是這樣嗎？可不可以是“JNDI Name:   ->jdbc/mydb”啊，謝謝！

    @w2j3z3j2h1

    java.lang.NullPointerException 說明你引用了一個null值，再看一下UserManager.findUserById方法，建議你直接寫一個簡單的程序測一下。

    jndi名稱可以是jdbc/mydb的，但是在使用的時候要ctx.lookup("java:comp/env/jdbc/mydb");

    其實只需要在\conf\Catalina\localhost下建個和web應用名一樣的xml就可以了，conf下的server.xml根本不用修改也好使 ，我試過了

    

    \conf\Catalina\localhost下 應用名.xml是這個應用所私有的，別的項目不能使用。而server.xml則是公有的

    我設置的在修改\conf\Catalina\localhost目錄下建立一個xml文件,我做了一個留言板的測試，在上面的目錄下建了叫guestbook.xml的文件，內容入下：

    <?xml version="1.0" encoding="UTF-8"?>
