当我检查预览并使用eclipse提供参数时它工作得很好但是当我尝试通过servlet传递它时它没有...我打算通过HTML接受来自用户的输入并将其传递给的Servlet
额外信息：查询在jrxml文件中定义，并且也提供了连接
不重复：Where to place a .txt file so that a java servlet can read it during runtime
第一次堆栈跟踪后的更多信息
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
代码我关注
HashMap map = new HashMap();
JasperPrint jasperPrint = null;
Connection connection = null;
map.put("uLimit","2");
try {
jasperPrint = JasperFillManager.fillReport("Ticket.jrxml",map,connection);
} catch (JRException e) {
e.printStackTrace();
}
}
