三层客户端的错误

[zdb1203]

本人用的是JB+Weblogic8.12,刚学!
现在我做的三层客户端都出现了错误,而且是同一个错误,如下:
-------------------------------------------------------------------------------------
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(NamingManager.java:640)

at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:243)

at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:280)

at javax.naming.InitialContext.lookup(InitialContext.java:347)

at HelloTestClient1.main(HelloTestClient1.java:165)

Exception in thread "main"
------------------------------------------------------------------------------
不知道如何解决(正在郁闷当中),请高手指点!
