请各位帮帮小弟!!
我用的是TOMCAT5.0.28，在ECLIPSE下使用果JSP
我遇到的问题：
1.
我的useBean.class(在eclipse下建的JAVA文件)文件要放到org.apache.jsp目录下，
JSP页才可以调用。现在我想把javaBean文件放到WEB-INF的class目录里，要如何的
部署呢？如果(没有部署前)Bean文件在class,我又如何在JSP页里用import引用？
2.
现在我的Bean文件就在org\apache\jsp目录下,
三个文件的代码如下：
html文件：
<div align="center">
<p>Enter your greeting word:</p>
<form method="post" action="usebean.jsp">
<input type="text" name="word">
<p><input type="submit" name="submit" value="submit"></p>
</form>
</div>
jsp文件：
<%@page language = "java" %>
<jsp:useBean id="Hello" class="Greeting" scope="request" >
<jsp:setProperty name="Hello" property="word" />
</jsp:useBean>
<p align="center">
<%
out.print(Hello.getWord());
%>
javaBean文件(已编译成类)：
package org.apache.jsp;
public class Greeting
{ private String word;
public Greeting(){}
private void setWord(String word)
{
this.word = word;
}
public String getWord()
{
return this.word;
}
}
出现的错误提示：

请各位解决!!!
<jsp:useBean id="Hello" class="Greeting" scope="request" >
<jsp:setProperty name="Hello" property="word" />
</jsp:useBean>
<p align="center">
<%
out.print(Hello.getWord());
%>
改成下面的试试
<jsp:useBean id="Hello" class="Greeting" scope="request" >
</jsp:useBean>
<p align="center">
<%
Hello.setWord("hello");
out.print(Hello.getWord());
%>
<jsp:useBean id="Hello" class="Greeting" scope="request" >
<jsp:setProperty name="Hello" property="word" />
</jsp:useBean>
<p align="center">
<%
out.print(Hello.getWord());
%>
改成下面的代码：
<jsp:useBean id="Hello" class="Greeting" scope="request" />
<jsp:setProperty name="Hello" property="word" value="hello" />
<p align="center">
<%
out.print(Hello.getWord());
%>
这样看行不行？
