http://www.cjsdn.net/post/view?bid=7&id=95089&tpg=1&ppg=1&sty=1&age=0#95089

本人的环境是Eclipse2.1.2+tomcat5.0+lomboz+mysql

$tomcat_home$/comm/lib下加入jndi.jar,mysql+jdbc驱动。

在tomcat的Sever.xml中的〈/Engine>前加入以下内容：

factory

org.apache.commons.dbcp.BasicDataSourceFactory

url

jdbc:mysql://localhost:3306/shop

driverclassname

com.mysql.jdbc.Driver

username

root

password

root

maxWait

3000

maxIdle

10

maxActive

100

在Webapps的Web.xml中加入以下内容：

connectDB test

jdbc/hibernate

javax.sql.DataSource

Container

测试代码如下：

package com.yzs.test.hibernate;

import java.io.IOException;

import java.io.PrintWriter;

import javax.naming.*;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.sql.*;

import java.sql.*;

/**

*/

public class testservlet extends HttpServlet {

protected void doGet(

HttpServletRequest request,

HttpServletResponse response)

throws ServletException, IOException {

//TODO Method stub generated by Lomboz

Context initctx=null;

Context ctx=null;

DataSource ds=null;

Connection conn=null;

Statement stmt=null;

ResultSet rs=null;

response.setContentType("text/html");

PrintWriter out=response.getWriter();

try {

initctx=new InitialContext();

ctx= (Context) initctx.lookup("jdbc:comp/env");

ds=(DataSource)ctx.lookup("jdbc/hibernate");

if(ds==null) throw new NamingException("no database");

} catch (NamingException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

try {

conn=ds.getConnection();

stmt=conn.createStatement();

rs=stmt.executeQuery("select * from brand");

rs.next();

out.println("");

out.println("

out.println("

test jndi");

out.println("");

out.println("

");

out.println(rs.getString("name"));

} catch (SQLException e4) {

// TODO Auto-generated catch block

e4.printStackTrace();

}

}

}

出现了Name jdbc:comp is not bound in this Context的问题，请各位大侠

帮忙看一下问题出在哪里。
