Question

根据我的说法，一切都很好，但我仍然得到一个例外，因为“org.apache.jasper.JasperException：无法为JSP编译类：”

请查看

RootDircetory： - CallActionJsp
RootDircetory / action.jsp
RootDircetory / index.html中
RootDircetory / META-INF
RootDircetory / WEB-INF /类/富/ Person.class
RootDircetory / web-inf / web.xml

=============================================== =========================

Index.html

<html>
<head>
<title>Index Page</title>
</head>
<body>

<form action="action.jsp" method="get">
<p align="left">Password: <input type="text" name="Password" /></p>
<BR>
<br>
<center><input type="SUBMIT" name="SUBMIT" /></center>
</form>
</body>
</html

Person.java

package foo;
public class Person
{
String name ;
    public void setName(String name)
    {
        this.name = name;
    }
    public String getName()
    {
        return name;
    }
}

action.jsp

<%@ page import="foo.*,java.util.Date"%>
<html>
<head>
<title>Action JSP</title>
</head>
<body>
<h1 align="center">Standard Actions are used Here.</h1>
<br>
<%
    Person p = new Person();
    Date date = new Date();
    out.print(date);
    String param = request.getParameter("Password");
    out.print("<br>"+param);
%>

<a href="CallActionJsp">Call Again </a>

</body>
</html>

的web.xml

        <url-pattern>/CallActionJsp</url-pattern>

</web-app>

快速猜测 - 由于Person中的小写web-inf，找不到RootDircetory/web-inf/classes/foo/Person.class？

WEB-INF必须是大写名称，您可以尝试重命名吗？
