同学们，谁能告诉我，我下面的代码怎么错了，执行不对

<body>
   <h1>request内置对象</h1>
   <%
       request.setCharacterEncoding("utf-8");//解决中文乱码问题，无法解决URL传递中文乱码问题。
   %>
   用户名:<%=request.getParameter("username")%>
   密码:<%=request.getParameter("password") %>
   爱好:<%
       String[] favorites = request.getParameterValues("favorite");
       for(int i = 0;i <　favorites.length;i++){
           out.println(favorites[i]+"  ");
       }
   %>
</body>

三月 17, 2019 10:02:59 上午 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet [jsp] in context with path [/MyJspProject] threw exception [java.lang.ClassNotFoundException: org.apache.jsp.request_jsp] with root cause
java.lang.ClassNotFoundException: org.apache.jsp.request_jsp

Stacktrace:] with root cause
org.apache.jasper.JasperException: Unable to compile class for JSP:

18:            out.println(favorites[i]+"  ");
19:        }

我只要把这段代码替换成老师，就没有任何问题。
