大家看看我的数据源配置哪里有错误
我的项目目录
D:\DBTEST
      |---WEB-INF
      |           |--web.xml
      |--dbtest.jsp

1.在%tomcat_home%\common\lib下拷贝了oracle的数据包classes12.jar
2.安装了oracle10g,端口号1158,数据库名orcl
3.conf/server.xml配置如下:
<Context   path= "/test "       docBase= "D:\dbtest "  
    debug= "1 "   reloadable= "true "   crossContext= "true ">
<Resource   name= "jdbc/orcl "  
                    auth= "Container "  
                    type= "javax.sql.DataSource "/>
        <ResourceParams   name= "jdbc/orcl ">
        <parameter>
<name> factory </name>
<value> org.apache.commons.dbcp.BasicDataSourceFactory </value>
        </parameter>
      <parameter>
<name> driverClassName </name>
<value> oracle.jdbc.driver.OracleDriver </value>
      </parameter>
      <parameter>
<name> url </name>
<value> jdbc:oracle:thin:@localhost:1158:ORCL </value>
      </parameter>
      <parameter>
  <name> username </name>
  <value> teacher </value>
      </parameter>
      <parameter>
  <name> password </name>
<value> teacher </value>
        ..其他参数略..
      </ResourceParams>
</Context>
4.web.xml配置如下:
  <resource-ref>
    <description> 数据源 </description>
    <res-ref-name> jdbc/orcl </res-ref-name>
    <res-type> javax.sql.DataSource </res-type>
    <res-auth> Container </res-auth>
  </resource-ref>
5.dbtest.jsp代码如下:
<%@   page   language= "java "   contentType= "text/html;charset=gb2312 "%>
<%@   page   import= "javax.naming.* "   %>
<%@   page   import= "java.sql.* "   %>
<%@   page   import= "javax.sql.* "   %>
<html>
<head>
<meta   http-equiv= "Content-Type "   content= "text/html;   charset=ISO-8859-1 ">
<title> Insert   title   here </title>
</head>
<body>

try
{
  Context   initCtx   =   new   InitialContext();
  Context   envCtx   =   (Context)initCtx.lookup( "java:comp/env ");
  DataSource   ds   =   (DataSource)envCtx.lookup( "jdbc/orcl ");
  Connection   con   =   ds.getConnection();
  Statement   stat   =   con.createStatement();
  ResultSet   rs   =   stat.executeQuery( "select   *   from   student ");
