本文介绍了一个简单的JSP页面与JavaBean交互的例子，包括如何通过表单提交数据到JSP，再由JSP传递给JavaBean进行处理，并最终展示处理结果。
index.jsp
------------------------------------------------------------
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<META NAME="Generator" CONTENT="EditPlus">

test.jsp
-------------------------------------------------------------
<%@ page contentType="text/html;charset=gb2312" import="test" %>
<jsp:useBean id="Test" scope="page" class="test">
<jsp:setProperty name="Test" property="*"/>
</jsp:useBean>
<html>
<body>
<%=Test.getContent()%>
<%=Test.getMessage()%>
</body>
</html>
<jsp:useBean id="Test" scope="page" class="test">
<jsp:setProperty name="Test" property="*"/>
</jsp:useBean>
<html>
<body>
<%=Test.getContent()%>
<%=Test.getMessage()%>
</body>
</html>
test.java
--------------------------------------------------------------
public class test
{
public String content;
public void setContent(String content)
{
this.content=content;
}
public String getContent()
{
return this.content;
}
public String getMessage()
{
return this.content;
}
}
{
public String content;
public void setContent(String content)
{
this.content=content;
}
public String getContent()
{
return this.content;
}
public String getMessage()
{
return this.content;
}
}
注意：如在JSP中使用property="*",则在javabean中使用的属性名应该与之前的"name"中的名字一样．
