昨天下了jasperreport的最新版本3.7.3看了下。弄了半天还是没能习惯他的报表制作方式。看了下他的打印是利用applet的来打印的。而且还需要客户端安装 十几MB的 jre 关于这个好坏，每个人都有自己的看法。今天我这里要说的是利用
jatoolsprinter控件来打印jasperreport的报表。控件大小只有100k左右 关于jasperreport的报表制作这里不做说明，我是在环境中跑了下jasperreport的demo运行界面如下
运行JSP Example 如下图
下面我们对demo中的html.jsp进行修改 用
jatoolsprinter来打印Jasperreport 的报表
蓝色部分为控件需要的内容

File reportFile = new File(application.getRealPath("/reports/WebappReport.jasper"));
if (!reportFile.exists())
throw new JRRuntimeException("File WebappReport.jasper not found. The report design must be compiled first.");
JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());
Map parameters = new HashMap();
parameters.put("ReportTitle", "Address Report");
parameters.put("BaseDir", reportFile.getParentFile());
JasperPrint jasperPrint =
JasperFillManager.fillReport(

new WebappDataSource()

JRHtmlExporter exporter = new JRHtmlExporter();
session.setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jasperPrint);
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);
exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "../servlets/image?image=");
exporter.exportReport();

因为
jatoolsprinter的打印是根据
