从jdk安装到jsp连接oracle数据库的相关配置

来源:网络时间:2011-04-26

  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"?>

  Context initCtx = new InitialContext();

  Context envCtx = (Context) initCtx.lookup("java:comp/env");

  DataSource ds = (DataSource) envCtx.lookup("jdbc/oracle");

  Connection conn = ds.getConnection();

  Statement stmt = conn.createStatement();

  ResultSet rst = stmt.executeQuery("select stuAge from students");

  while (rst.next()) {

  out.println(rst.getInt(1));

  }

  conn.close();

  } catch (Exception e) {

  e.printStackTrace();

  }
