这个找回密码的getPassword.jsp出现500错误了，帮忙看一下。

这个是什么原因？应该在哪里修改什么东西？网上查了挺多资料，无从下手。
本人新手，各位路过的帮忙指点一下，0.0001也大于0呀！

The value for the useBean class attribute com.ntt.ozone.Email is invalid.
是不是包问题
这是phone文件夹下的getpassword.jsp出现的问题，根目录下也有个findpassword.jsp就没问题。包问题的话怎么看？
org.apache.jasper.JasperException:   页面解析错误。。应该是你的JSP页面语法的问题，把代码上上来

com.ntt.ozone.Email 这个javabean里的各个属性名字是否与jsp一致呢请核对！
java bean 里不是好多private 啥的属性么
你再看看你jsp里用到是不是与它一致呢
你懂javabean 的功能吧？javabean是干嘛的？
usebean这句是干嘛的？你要是理解这两个问题你就明白了
org.apache.jasper.JasperException: /imode/getPassword.jsp (line: 6, column: 0) The value for the useBean class attribute com.ntt.ozone.Email is invalid.这句话的意思是你的javabean com.ntt.ozone.Email没有定义
<jsp:useBean id="jmail" class="com.ntt.ozone.Email" scope="session" />
这行代码没用到，删除后网站就正常了。
