1.安裝jdk(版本6u7);
2.配置jdk環境變量(安裝目錄: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.安裝 tomcat(版本6.0.20)
4.配置tomcat環境變量（安裝目錄:D:/tools/tomcat6.0）
1).CATALINA_HOME=D:/tools/tomcat6.0;
2).CATALINA_BASE=D:/tools/tomcat6.0;
3).CLASSPATH後面追加"%CATALINA_HOME%/lib/servlet-api.jar;"
5.安裝oracle數據庫(版本10g)
數據庫名：orcl
用戶名：mydata
密碼：oracle
6.配置tomcat與oracle的連接
1).D:/tools/tomcat6.0/conf/server.xml追加如下內容：
<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>
說明：①、path="/test"(/test爲tomcat中webapps目錄下的工程文件夾)
②、docBase="D:/tools/tomcat6.0/webapps/test"(path中工程文件夾所在的絕對路徑)
③、username="mydata"(oracle數據庫的用戶名)
④、password="oracle"(oracle數據庫的密碼)
⑤、url="jdbc:oracle:thin:@127.0.0.1:1521:ORCL"/>(ORCL爲oracle數據庫名)
2).
在D:/tools/tomcat6.0/lib文件夾裏放入oracle驅動文件ojdbc14.jar(此文件可在網上下載)
3).在webapps下新建工程文件夾test，在test文件夾下新建WEB-INF文件夾和test.jsp文件；
在WEB-INF文件夾下新建lib文件夾和web.xml文件；在lib文件夾下放入oracle驅動文件
ojdbc14.jar(此文件可在網上下載)
web.xml文件內容如下：
<?xml version="1.0" encoding="ISO-8859-1"?>
