javabean 必须放在包中嘛?

我放在包中就不出错,
一不放包中就出错
tomcat5+jdk1.42
有规定说必须放包中没?
错误如下:
org.apache.jasper.JasperException: Unable to compile class for JSP

#1

你最好放在包中，好像JSP中引用的對象必須是有package的

#2

你把代码改一下, 不必都放在包里.

#3

应该放包里吧。
关注一下

#4

我改了,然后就出现上面得错误!
只要没放在包中就错,郁闷死了1

#5

是你代码的问题。可以不用打包

#6

最好是package一下，否则需要在页面中import该bean类

#7

楼主，我测试了，好像是这样的，但书上没这规定啊，谁来给个权威解释！
