[解决办法]
配置数据源:
一、配置环境变量:
softe version:tomcat5.0.12/mysql4.1.7/mysql_driver---mysql-connector-java-3.1.4-beta-bin.jar
mysql驱动程序可从www.mysql.com官方网站下载
路径:tomcat5在d:\myweb\tomcat5;mysql在C:\Program Files\MySQL\MySQL Server 4.1
Path(在原来的基础上加上):d:\myweb\tomcat5\bin;d:\myweb\jdk1.4;d:\myweb\jdk1.4\bin;
d:\myweb\tomcat5\common\lib\servlet-api.jar;C:\Program Files\MySQL\MySQL Server 4.1\bin
CLASSPATH:d:\myweb\tomcat5\common\lib\servlet-api.jar;d:\myweb\tomcat5\common\lib\jsp-api.jar
JAVA_HOME:d:\myweb\jdk1.4
CATALINA_HOME:d:\myweb\tomcat5
二、建立测试数据库
在mysql中建立一个forumdb数据库,同时创建一个表member如下:
create database forumdb;
create table member
(
id int,
name varchar(6)
);
然后插入两条测试数据如下:
insert into member values(1, "zhang ");
insert into member values(2, "wang ");
至此,数据库准备完毕。
三、配置server.xml
注:我的web在d:\myweb\myapps
首先要将mysql的驱动程序放到d:\myweb\tomcat5\common\lib下面,一定要放 ".jar "的文件,如是 ".zip "的文件直接改为.jar即可。
用文本编辑器打开D:\tomcat5\conf\server.xml,找到 </host> 结束标志,然后在之前加上如下语句:
<Context path= "/myapps " docBase= "d:\myweb\myapps " debug= "0 "
reloadable= "true " >
<Resource name= "jdbc/DBConnection "
auth= "Container "
type= "javax.sql.DataSource " />
<ResourceParams name= "jdbc/DBConnection ">
<parameter>
<name> factory </name>
<value> org.apache.commons.dbcp.BasicDataSourceFactory </value>
</parameter>
<!-- Maximum number of dB connections in pool. Make sure you
configure your mysqld max_connections large enough to handle
all of your db connections. Set to 0 for no limit.
-->
<parameter>
<name> maxActive </name>
<value> 10 </value>
</parameter>
<!-- Maximum number of idle dB connections to retain in pool.
Set to 0 for no limit.
-->
<parameter>
<name> maxIdle </name>
<value> 3 </value>
</parameter>
<!-- Maximum time to wait for a dB connection to become available
in ms, in this example 10 seconds. An Exception is thrown if
this timeout is exceeded. Set to -1 to wait indefinitely.
Maximum time to wait for a dB connection to become available
in ms, in this example 10 seconds. An Exception is thrown if
this timeout is exceeded. Set to -1 to wait indefinitely.
-->
<parameter>
<name> maxWait </name>
<value> 10000 </value>
</parameter>
<!-- MySQL dB username and password for dB connections -->
<parameter>
<name> username </name>
<value> root </value>
</parameter>
<parameter>
<name> password </name>
<value> 1234 </value>
</parameter>
<!-- Class name for mm.mysql JDBC driver -->
<parameter>
<name> driverClassName </name>
<value> com.mysql.jdbc.Driver </value>
</parameter>
<!-- The JDBC connection url for connecting to your MySQL dB.
The autoReconnect=true argument to the url makes sure that the
mm.mysql JDBC Driver will automatically reconnect if mysqld closed the
connection. mysqld by default closes idle connections after 8 hours.
-->
<parameter>
<name> url </name>
<value> jdbc:mysql://localhost:3306/forumdb?autoReconnect=true </value>
</parameter>
</ResourceParams>
</Context>
再次提醒:一定要放在 </host> 之前!
四、配置web.xml
web.xml位于d:\myweb\myapps\WEB-INF下,也即是你的WEB里的web.xml。
同样用文本编辑器打开web.xml,然后加入如下语句(在 <web-app> 与 </web-app> 之间)
<resource-ref>
<description> DB Connection </description>
<res-ref-name> jdbc/DBConnection </res-ref-name>
<res-type> javax.sql.DataSource </res-type>
<res-auth> Container </res-auth>
</resource-ref>
五、编写测试jsp page。
在d:\myweb\myapps\下编写一个dbtest.jsp,代码如下:
<%@ page import= "java.io.*,java.util.*,java.sql.*,javax.sql.*,javax.naming.* "%>
<%@ page contentType= "text/html;charset=GB2312 "%>
<html>
<head> <title> DataSourse Connection Test </title> </head>
<body>
<%
try{
java.sql.Connection con;
Statement stmt;
ResultSet rs;
Context ctx = new InitialContext();
DataSource ds=(DataSource)ctx.lookup( "java:comp/env/jdbc/DBConnection ");
con=ds.getConnection();
stmt=con.createStatement();
rs=stmt.executeQuery( "select * from member ");
while(rs.next()){
out.print(rs.getInt(1);
out.print(rs.getString(2));
}
rs.close();
stmt.close();
con.close();
}catch(Exception e){
out.print(e.getMessage());
}
%>
</body>
</html>
六、开始测试
运行tomcat.bat,打开IE在地址栏中输入:http://localhost:8080/myapps/dbtest.jsp
[解决办法]
配置TOMCAT5.5以上版本不带ADMIN这样配置(COMMON/LIB下有驱动)
修改%TOMCAT_HOME%/conf/server.xml文件,在 <GlobalNamingResources> </GlobalNamingResources> 之间
添加以下内容:
<Resource
name= "jdbc/****** "
type= "javax.sql.DataSource "
password= "123456 "
driverClassName= "com.microsoft.jdbc.sqlserver.SQLServerDriver "
maxIdle= "2 "
maxWait= "5000 "
username= "sa "
url= "jdbc:microsoft:sqlserver://localhost;DatabaseName=quickstart "
maxActive= "4 "/>
修改%TOMCAT_HOME%/webapps/yourweb/WEB-INF下的web.xml文件,在 <web-app> </web-app> 之间添加以下 <resource-ref>
<description> sqlserverDB Connection </description>
<res-ref-name> jdbc/****** </res-ref-name>
<res-type> javax.sql.DataSource </res-type>
<res-auth> Container </res-auth>
</resource-ref>
在%TOMCAT_HOME%/conf/Catalina/localhost下新建一个与你web文件夹同名的xml文件
<?xml version= "1.0 " encoding= "UTF-8 "?>
<Context>
<Resource
name= "jdbc/****** "
type= "javax.sql.DataSource "
password= "123456 "
driverClassName= "com.microsoft.jdbc.sqlserver.SQLServerDriver "
maxIdle= "2 "
maxWait= "5000 "
username= "sa "
url= "jdbc:microsoft:sqlserver://localhost;DatabaseName=quickstart "
maxActive= "4 "/>
</Context> 根据个人具体情况进行相应修改。
使用ADMIN配置的
在\conf\Catalina\localhost下你的工程名。XML中加入
<ResourceLink name= "jdbc/**** " global= "jdbc/**** " type= "javax.sql.DataSource "/>
基本就可以了。。。。
6.0我没用过
