linxu下报JasperRunManager cannot be resolved错误
最近在学jasperreport，运行了一个例子，在Windows下能跑，但是在Linux下出了问题，不解。jsp文件如下:
<%@ page contentType="text/html;charset=utf-8"%>
    <%@ page import="net.sf.jasperreports.engine.*"%>
    <%@ page import="java.util.*"%>
    <%@ page import="java.io.*" %>
    <%@ page import="java.sql.*" %>
    <%
    String ctxpath = request.getContextPath();

//    try{

Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://10.1.16.163:3306/esocc_0702?user=root&password=123");
//}catch(ClassNotFoundException e){
//System.out.println("Sorry,can't find the driver");
//e.printStackTrace();
//}catch(SQLException e1){
//System.out.println("Sorry,i don't know");
//e1.printStackTrace();
//}catch(Exception e2){
//System.out.println("It's wrong");
//}

File reportFile = new File(this.getServletContext().getRealPath("/test.jasper"));
Map para = new HashMap();
try{
JasperRunManager.runReportToHtmlFile(reportFile.getPath(),para,conn);
response.sendRedirect(ctxpath+"/test.html");
}catch(Exception e){
System.out.println(e.getMessage());
}
    %>

错误提示如下:

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 21 in the jsp file: /reportRun.jsp
JasperRunManager cannot be resolved
18: File reportFile = new File(this.getServletContext().getRealPath("/test.jasper"));
19: Map para = new HashMap();
20: try{
21: JasperRunManager.runReportToHtmlFile(reportFile.getPath(),para,conn);
22: response.sendRedirect(ctxpath+"/test.html");
23: }catch(Exception e){
24: System.out.println(e.getMessage());

不知道是什么原因，我的jar包是直接把windows下的包(windows下正常运行)复制到Linux下的，不知道问题在哪，是不是少导入了包？导致不能解析JasperRunManager类？求大神指点迷津，谢谢 linxu上报JasperRunManager cannot be resolved异常
[解决办法]
"/test.jasper"换成 "\test.jasper"，是不是因为windows和Linux下的路径差异导致的，或者是目录结构
