1.安装jdk(版本6u7);

2.配置jdk环境变量(安装目录:D:\tools\java\jdk1.6.0_07):

1). JAVA_HOME = D:\tools\java\jdk1.6.0_07;

2). Path的最前面追加"D:\tools\java\jdk1.6.0_07\bin;D:\tools\java\jre1.6.0_07\bin";

3). CLASSPATH = D:\tools\java\jdk1.6.0_07\lib;D:\tools\java\jdk1.6.0_07\lib\tools.jar;

3.安装 tomcat(版本6.0.20)

4.配置tomcat环境变量（安装目录:D:\tools\tomcat6.0）

1).CATALINA_HOME=D:\tools\tomcat6.0;

2).CATALINA_BASE=D:\tools\tomcat6.0;

3).CLASSPATH后面追加"%CATALINA_HOME%\lib\servlet-api.jar;"

5.安装oracle数据库(版本10g)

数据库名：orcl

用户名：mydata

密码：oracle

6.配置tomcat与oracle的连接

1).D:\tools\tomcat6.0\conf\server.xml追加如下内容：

<Context path="/test" reloadable="true" docBase="D:\tools\tomcat6.0\webapps\test" debug="0" >

<Resource name="jdbc/oracle" auth="Container" type="javax.sql.DataSource"

maxActive="5" maxIdle="4" maxWait="10000"

username="mydata" password="oracle" driverClassName="oracle.jdbc.driver.OracleDriver"

url="jdbc:oracle:thin:@127.0.0.1:1521:ORCL"/>

</Context>

说明：①、path="/test"(/test为tomcat中webapps目录下的工程文件夹)

②、docBase="D:\tools\tomcat6.0\webapps\test"(path中工程文件夹所在的绝对路径)

③、username="mydata"(oracle数据库的用户名)

④、password="oracle"(oracle数据库的密码)

⑤、url="jdbc:oracle:thin:@127.0.0.1:1521:ORCL"/>(ORCL为oracle数据库名)

2).

在D:\tools\tomcat6.0\lib文件夹里放入oracle驱动文件ojdbc14.jar(此文件可在网上下载)

3).在webapps下新建工程文件夹test，在test文件夹下新建WEB-INF文件夹和test.jsp文件；

在WEB-INF文件夹下新建lib文件夹和web.xml文件；在lib文件夹下放入oracle驱动文件

ojdbc14.jar(此文件可在网上下载)

web.xml文件内容如下：

<xml version="1.0" encoding="ISO-8859-1">
