hyxdx

大家好：
    有谁成功配置 sun one webServer 6.1 JDBC 连接池技术的？
    我的配置如下：
    server.xml
      .......
    <RESOURCES>;
      <JDBCCONNECTIONPOOL name="poolitdb" datasourceclassname="oracle.jdbc.pool.OracleDataSource" st
eadypoolsize="8" maxpoolsize="32" poolresizequantity="2" idletimeout="300" maxwaittime="60000" conne
ctionvalidationrequired="off" connectionvalidationmethod="auto-commit" validationtablename="" failal
lconnections="off" transactionisolationlevel="read-uncommitted" isolationlevelguaranteed="off">;
        <ROPERTY name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>;
        <ROPERTY name="URL" value="jdbcracle:thin127.0.0.1:6633:itdb"/>;
        <ROPERTY name="User" value="itdb"/>;
        <ROPERTY name="assword" value="windows"/>;
      </JDBCCONNECTIONPOOL>;
      <JDBCRESOURCE jndiname="jdbc/itdb" poolname="poolitdb" enabled="on"/>;
    </RESOURCES>;

      ........

delault-web.xml

............
<resource-ref>;
        <description>;JNDI JDBC DataSource</description>;
        <res-ref-name>;jdbc/itdb</res-ref-name>;
        <res-type>;javax.sql.DataSource</res-type>;
        <res-auth>;Application</res-auth>;
    </resource-ref>;
..........


jsp 调用：
<%@page import="java.sql.*"%>;
<%@ page import="javax.sql.*" %>;
<%@ page import="javax.naming.*" %>;
<%@page contentType="text/html;charset=gb2312"%>;
<%
    try {
        Context initContext = new InitialContext();
        //Context envContext  = (Context)initContext.lookup("java:/comp/env";
        DataSource ds = (DataSource)initContext.lookup("java:/comp/env/jdbc/itdb";
        Connection conn = ds.getConnection();
                                                                              
        if(!conn.isClosed())
            out.println("資料庫連線測試成功！";
        conn.close();
    }
    catch(SQLException e) {
        out.println(e.toString());
    }
%>;


出错误信息：javax.naming.NamingException: Cannot create resource instance

请指点！！！！！！
