刚学JSP,有关javabean的问题(50分)

我使用Tomcat做为运行环境，我不想使用tomcat默认的目录，自己建了一个目录，并已经配好了
虚拟目录。如果我想把javabean也放在这个虚拟目录里请问要做如何设置？？？？？？？？

放到WEB-INF/classes目录下面就可以。注意包路径

还是没有成功，我说详细点。
tomcat安装目录　d:/tomcat
自己建站的虚拟目录 d:/jsp在此目录中建立了一个　WEB-INF/classes　目录
我把bean放在WEB-INF/classes目录中
但是执行结果出错，情况如下：
HTTP Status 500 -

用Tomcat管理器就是可建自己的虚拟目录。
步骤如下：
1）http://hostort进入Tomcat管理器
2）点击Tomcat Administration，输入用
户和密码
3）点击Service，右边下拉列表框选择
Create New defaultcontext按要求填写
就可以。

你在web-inf/classes下自己建一个文件夹取名叫num应该就可以了吧，根据你jsp的编译错好像是这个问题

多人接受答案了。
