JasperReport有如下幾個主要的Manager：

對于上述對象的詳細(xì)說明請參閱JasperReport的文檔。

例程：

public static void main(String[] args) {

    try {

      Class.forName("org.gjt.mm.mysql.Driver");

      Connection con = DriverManager.getConnection(

          "jdbc:mysql://wes:3306/umpdb?useUnicode=true&characterEncoding=GBK", "root", "elite");

      File f1 = new File("Account.jrxml");

      File f2 = new File("Contact.jrxml");

      JasperReport main = JasperCompileManager.compileReport(f1

          .getAbsolutePath());

      JasperReport report = JasperCompileManager.compileReport(f2

          .getAbsolutePath());

      Map props = new HashMap();

      props.put("subreport", report);

      JasperPrint print = JasperFillManager.fillReport(main, props,con);

      //JasperPrintManager.printReport(print,true);

      JasperExportManager.exportReportToPdfFile(print, "a.pdf");

      //JasperRunManager.runReportToPdfFile("Account.jasper", "a.pdf", props, con);

    } catch (ClassNotFoundException e) {

      // TODO 自動生成 catch 塊

      e.printStackTrace();

    } catch (SQLException e) {

      // TODO 自動生成 catch 塊

      e.printStackTrace();

    } catch (JRException e) {

      // TODO 自動生成 catch 塊

      e.printStackTrace();

    }
