JSP导入类导致错误

这是我第一次尝试JSP。我正在使用TOMCAT8和Geany编写。我将应用程序文件夹放在/var/lib/tomcat8/webapps/Jproject和/var/lib/tomcat8/webapps/Jproject/WEB-INF/classes的类中。JSP导入类导致错误

我的课文件/var/lib/tomcat8/webapps/Jproject/WEB-INF/classes/test.class是;

public class test 
{ 
public static void PP() 
{ 
System.out.println("yoyo"); 
} 
}

和我的index.jsp (/var/lib/tomcat8/webapps/Jproject/index.jsp)是;

<%@ page import="Jproject.test.*" %> 
<DOCTYPE! html> 
<html> 
<head> 
<title>Project</title> 
</head> 
<body> 
<% String x = "java"; 
    out.println("Hello " + x + "Worlds"); 
test.PP(); %> 
</body> 
</html>

当我在浏览器上运行它http://localhost:8080/Jproject/我得到以下错误;

HTTP Status 500 - Unable to compile class for JSP: 

type Exception report 

message Unable to compile class for JSP: 

description The server encountered an internal error that prevented it from fulfilling this request.

我在做什么错了？谢谢你的帮助！

您必须在src文件夹下创建类不是WEB-INF文件夹和jsp文件创建在webapp文件夹下。

我没有使用eclipse。我正试图把它写在Geany上。有没有一个XML文件，我必须创建？ – bluepinto
