Need to specify class name in environment or system property

[zhenxiuershibaxing]

运行程序出错：
javax.naming.NoInitialContextException: 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
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
请教一下是什么地方引起错误，如何改。（初学者）

容器抛出来的应该有更详细的错误吧。
