求救，我按照CSDN上的文档配置好了TOMCAT连接池，为什么不行

Question

补充TOMCAT用的是4.1.27，数据库是ORACLE9
SERVER.XML配置如下：
        <!-- Tomcat Root Context -->          <Context path="" docBase="E:\xyq\eiro\webapp" debug="0"> 
                     
          <Resource name="jdbc/OracleDB" auth="Container" type="javax.sql.DataSource"/> 
                             
          <ResourceParams name="jdbc/OracleDB">
                             
            <parameter>
                                    
  <name>factory</name>

          </Context>

Answer 1

你的应用 WEB-INF\web.xml要加上
<description> Mysql Test App </description>
  <resource-ref>
    <description> DB Connection</description>
    <res-ref-name>jdbc/OracleDB</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
  </resource-ref>
其实连接池都已经是j2ee的范畴了，都用jndi了

Answer 2

web.xml已经配置了啊报错如下：
java.sql.SQLException: Io 异常: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=153092352)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
