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
