问如何避免获取日志:org/apache/commons/java.lang.NoClassDefFoundError/LogFactory

EN

我有一个NetBeans项目，其中我想要设计贾斯珀报告，当我通过JasperFillManager.fillReport填充报告时，我发现了一个错误信息。

我该如何解决这个问题？

我使用过iReport 5.0.0和JasperReports库5.1.0。

我的代码描述如下

try {
    String reportName = "./rptJobList.jasper";
    InputStream is = new FileInputStream(reportName);
    Class.forName("com.mysql.jdbc.Driver");
    Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/js001?user=root&password=admin");
    JasperPrint jasperPrint = JasperFillManager.fillReport(is, null, con);
    JasperViewer jv = new JasperViewer(jasperPrint);
    jv.setVisible(true);
} catch (Exception ex) {
}

例外情况是：
