Как избежать получения java.lang.noclassdeffounderror: org/apache/commons/журнал/logfactory ⇐ JAVA

[Anonymous]

У меня есть проект netbeans , в котором я хочу спроектировать отчет Jasper, когда я заполняю отчет через

Код: Выделить всё

JasperFillManager.fillReport

затем я нашел сообщение об ошибке. < /p>

Как я могу это решить?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) {
}
< /code>
