Answer 1

找不到相应的类文件
当你编译源文件 以后都会生成一些类文件：***.class
执行时要用java(main所在的类)
如果找不到相应的类，执行就会出现NoClassDefFoundError的异常

如果不是你写的程序..那么就是网站的问题.和你机器无关!

Answer 2

没找到相关类文件，

com.ctint.app.singlecustomer.CustomerFacade.(CustomerFacade.java:34)

Answer 3

PageContextImpl.java:69

Answer 4

没有找到你调用的Class，一般情况是相关的包没有导入

Answer 5

请问下,这个是在什么情况下出现的问题?
