火狐控制台报如题的错,请问如何解决:
原文件,百度富文本编辑器controller.jsp

 <%@ page language="java" contentType="text/html; charset=UTF-8"
    import="com.baidu.ueditor.ActionEnter"
    pageEncoding="UTF-8"%>
<%@ page trimDirectiveWhitespaces="true" %>
<%

    request.setCharacterEncoding( "utf-8" );
    response.setHeader("Content-Type" , "text/html");

    String rootPath = application.getRealPath( "/" );

    out.write( new ActionEnter( request, rootPath ).exec() );
