把这个deptReport.jasper文件复制到Web项目里的reports文件夹中

导入JasperReport的包，包可以从以下路径找到.

Ireport安装路径\iReport-3.7.6\ireport\modules\ext

把这里所有的包引到Web项目里，引入oracle的jdbc驱动，接下来进行编程，以Servlet为例

1，生成报表并且以HTML形式在网页上显示

Servlet的主要逻辑代码如下：

 request.setCharacterEncoding("utf-8");

         // 接收查询参数，将来这个参数就是我们在报表中定义的parDname

         String deptName = request.getParameter("dname");

         // 报表文件路径，我们用ireport做的jasper文件路径

         // JasperReport需要jasper文件的真实路径

         String reportPath = request.getSession().getServletContext()

                 .getRealPath("/reports/deptReport.jasper");

         // 报表参数，jasper文件可能不只一个参数

 // 在程序里，用一个Map对象，向jasper文件传递他需要的参数

         Map reportParameters = new HashMap();

         reportParameters.put("parDname", deptName);

         // 报表连数据库所用的数据连接

         // 因为报表直接以数据库为数据源，所以在这里需要给jasper文件一个jdbc连接

         Connection con = null;

         // 清空响应流

         response.reset();

         // 设置输出格式

         response.setContentType("application/html");

         // 创建JDBC连接

         Class.forName("oracle.jdbc.OracleDriver");

         con = DriverManager.getConnection(

                 "jdbc:oracle:thin:@oracle10:1521:oracle", "scott", "tiger");

         // JasperReport提供的类，用于生成一个HTML文件

         JasperRunManager.runReportToHtmlFile(reportPath, reportParameters, con);

         response.sendRedirect(request.getContextPath()

                 + "/reports/deptReport.html");

 /*

  * 如果要在网页上显示PDF文件，把前两句去掉，放开这段注释

          * ServletOutputStream out = response.getOutputStream();

          * //从jasper报表生成PDF字节

          * byte[] pdfBytes = JasperRunManager.runReportToPdf(reportPath, reportParameters, con);

          * //设置输出内容长度

 * response.setContentLength(pdfBytes.length); //将PDF写入报表

          * out.write(pdfBytes, 0, pdfBytes.length);

          * out.flush();

          * out.close();

          */

         // 关闭数据连接

     con.close();

这里只写出逻辑代码，实际用的时候，加上各种异常的处理。

2，导出PDF和Excel文件

Servlet的逻辑代码如下，还是没写异常处理，开发时加上

 // 接收查询参数

         request.setCharacterEncoding("utf-8");

         String deptName = request.getParameter("dname");

 // 在请求的时候多加一个参数，标识要生成文件的格式是xls还是pdf

         String format = request.getParameter("format");

         // 报表文件路径

         String reportPath = request.getSession().getServletContext()

                 .getRealPath("/reports/deptReport.jasper");

         // 报表参数

         Map reportParameters = new HashMap();

         reportParameters.put("parDname", deptName);

         // 报表查数据库的连接

         Connection con = null;

         // 清空响应流

         response.reset();

         // 设置输出格式

         String contentType = "pdf";

         if ("xls".equals(format.toLowerCase())) {

             contentType = "xls";

         }

         response.setContentType("application/" + contentType);

         // 设置输出文件名

         response.setHeader("Content-Disposition",

                 "attachment; filename=deptReport." + contentType);

         // 输出流，用于向浏览器传送pdf文件

         ServletOutputStream out = null;

         // 创建数据连接

         Class.forName("oracle.jdbc.OracleDriver");

         con = DriverManager.getConnection(

                 "jdbc:oracle:thin:@oracle10:1521:oracle", "scott", "tiger");

         // 取响应流

         out = response.getOutputStream();

         // 创建导出器,JasperReport提供的类

         // 这里以xls和pdf为例，如果需要生成其他格式的文件，用其他导出器就行

         JRAbstractExporter exporter = new JRRtfExporter();

         // PDF导出器

         if ("pdf".equals(format.toLowerCase())) {

             exporter = new JRPdfExporter();

         } else if ("xls".equals(format.toLowerCase())) { // excel导出器

             exporter = new JRXlsExporter();

             exporter.setParameter(

                     JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, false);

         }

         // 加载报表文件

         JasperReport report = (JasperReport) JRLoader.loadObject(reportPath);

         // 创建JasperPrint对象

         JasperPrint jasperPrint = JasperFillManager.fillReport(report,

                 reportParameters, con);

         // 设置要输出的jasper对象

         exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

         // 设置输出流

         exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, out);

         // 导出

         exporter.exportReport();

         out.flush();

         out.close();

     con.close();

到此为止，JasperReport + ireport 集成报表到Web程序的一般步骤就说完了，本说明中所提到的报表源文件及Web示例，随文档一起，可以参实际例子来学习Jasper 和 ireport
