tomcat 连接池的问题
tomcat5.0.28 连接池配置如下：
<?xml version= '1.0 ' encoding= 'utf-8 '?>
<Server>
<Listener className= "org.apache.catalina.mbeans.ServerLifecycleListener "/>

</Service>
</Server>
在程序中调用出现如下异常：Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
在jsp中调用出现如下异常：Name java:comp is not bound in this Context

已经困惑好多天了，请各位高手指教。在线等待！


[解决办法]
帮顶下
[解决办法]
<Resource name= "jdbc/wyl " type= "javax.sql.DataSource "/>
可能和在Java中调用的不一致

Tomcat 5.0好像需要另外建一个XML文件，放在Tomcat 5.0\conf\Catalina\localhost目录之下，
文件名为你发布的webapps下的目录名字.内容为
<Context path= "/manager " docBase= "你的目录名 ">
<ResourceLink name= "jdbc/wyl " global= "jdbc/wyl "
type= "javax.sql.DataSource "/>

</Context>
