我原来的项目就可以访问数据源，新建的这个确怎么都不行，请个路大侠帮忙分析一下！谢谢拉

Answer 3

Error creating bean with name 'dataSource' defined in ServletContext resource 这错误应该是
javax.naming.NamingException: Cannot create resource instance
不能建立 资源的实例
我认为是数据源的问题呀你试下在conf/Catalina/localhost下建立与你WEBAPP同名的***.xml
tomcat5.5 加入下面的内容 要是tomcat6.0的话 连Catalina和localhost这两个文件夹也自己建立
<Context path="/firsttest" reloadable="false" docBase="First" >
       <Resource 
        name="jdbc/orcl" 
        auth="Container" 
        type="javax.sql.DataSource" 
        factory="org.logicalcobwebs.proxool.ProxoolDataSource" 
        proxool.alias="orcl" 
        user="infocenter" 
        password="infocenter" 
        delegateProperties="foo=bar" 
        proxool.driver-url="jdbc:oracle:thin:@192.168.0.178:1521:XE" 
        proxool.driver-class="oracle.jdbc.driver.OracleDriver"
        proxool.house-keeping-sleep-time = "90000"
        proxool.maximum-new-connections = "20"
        proxool.prototype-count = "3"
        proxool.maximum-connection-count = "10"
        proxool.minimum-connection-count = "3"
        proxool.house-keeping-test-sql = "select CURRENT_DATE from dual"
        proxool.test-before-use = "true"
        /> 
</context>tomcat5.0的话
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="*****" path="/****" workDir="work\Catalina\localhost\******">
  <ResourceLink global="jdbc/orcl" name="jdbc/orcl"type="javax.sql.DataSourcer"/>
</Context>
 LZ根据自己情况修改那些****吧
