javabean的使用问题

[javacountry]

我做了几个javabean,然后用jsp调用, 其它几个javabean都没有什么,总是报classnotfoundexception,何故?
我的javabean都是在jbuilder中编写调试, 最后再用javac进行编译的,我怎么找都找不出问题之所在,请大侠帮忙.

你jsp的useBean里面是否写了“mybeans.className”,还有你的bean放在那个目录下，是否加上了package（mybeans）的目录结构？

[wes109]

自己找一下吧，可能是笔误。好好看一下你的jsp文件

[Hikaru]

总的来说就是你bean没放对地方，jsp找不到。
可以通过设classpath的方法来指定。
或则把bean放到指定的bean目录下面。

我的bean应该是放对了地方呀,因为我是有几个javabean,都放在一个目录下面,其它的都能够找到的

另外我把javabean 的源码附在下面,请诸位高手指点
