Tomcat 5.5 和 tomcat5.0 的配置是不一樣的 ,Tomcat5.5 的配置如下 :

在 server.xml 文件中配置如下 :

<Context path="/Recommend" reloadable="true" docBase="C:\eclipse\workspace\Recommend" workDir="C:\eclipse\workspace\Recommend\work">

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

?????????????? maxActive="100" maxIdle="30" maxWait="10000"

username="spstest" password="sps0922"

driverClassName="oracle.jdbc.driver.OracleDriver"

?????????????? url="jdbc:oracle:thin:@192.168.6.15:1521:ora9"/>

</Context>

在 C:\Tomcat 5.5\common\lib 目錄下拷入 class12.jar

class12.jar 是 oracle 的 jdbc 的驅(qū)動(dòng)程序不包

?

在 web.xml 中修改代碼

<description>oralceDB</description>

<resource-ref>

<description>DB Connection</description>

<res-ref-name>jdbc/myoracle</res-ref-name>

<res-type>javax.sql.DataSource</res-type>

<res-auth>Container</res-auth>

</resource-ref>

?

測(cè)試代碼

? <%@ page import="javax.naming.Context" %>

<%@ page import="javax.sql.DataSource"%>

<%@ page import="javax.naming.InitialContext"%>

<%@ page import="java.sql.*"%>

? <%

? ? ? DataSource ds = null;

???? Context jndiCntx = new InitialContext();

? ?? ? ds =(DataSource)jndiCntx.lookup( "java:comp/env/jdbc/myoracle");

??????????

? ?? if(ds!=null){

?? ?? ? System.out.println("Connection is OK!");

?? ?? ? }

??? else

??? {

??? System.out.println("Connection is fail!"); ???

??? }

???

??? Connection cn=ds.getConnection();

??? if(cn!=null){

???? System.out.println("cn is Ok!");

???? }

???? else

???? {

????? System.out.println("cn is fail!"); ????

???? } ???

????

??? // Statement stmt = cn.createStatement();

??? // ResultSet rst = stmt.executeQuery("select * from BOOK");

?? // ? out.println("<p>rst is Ok!" + rst.next());

?? // ? while(rst.next()){

?? // ???? System.out.println("<P>BOOK_CODE:" + rst.getString(1));

?? // ? } ????

??? cn.close();
