Question

以下是我的代码。我希望它将alreaady制作的jrxmlFile显示为pdf，但是我得到了一个execption

Connection con = null;

try {
    Class.forName("org.apache.derby.jdbc.ClientDriver");

    con = DriverManager.getConnection("jdbc:derby://localhost:1527/WPSJSP", "athif", "athif");//dbpassword

    String jrxmlFile = "E:/web/BirthdayPie.jrxml";
    InputStream input = new FileInputStream(new File(jrxmlFile));

    JasperReport jasperReport = JasperCompileManager.compileReport(jrxmlFile);
    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, con);

    OutputStream outStream = response.getOutputStream();
    JasperExportManager.exportReportToPdfStream(jasperPrint, outStream);

    response.getOutputStream().flush();
    response.getOutputStream().close();
} catch (Exception e) {
    e.printStackTrace();
} finally {
    if (con != null) {
        con.close();
    }
}

我做了很多研究，包括this，this and this等。请帮忙。

正如您在stacktrace中看到的那样：

[javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/joda/time/ReadablePartial]

您需要将joda-time.jar添加到类路径中。
