我创建了一个将使用JasperReports API的 Java 项目。我已经在NetBeans内部和外部（同一台机器）进行了测试，它工作正常。但是当我尝试在另一台机器上运行它时，报告不会加载。
我的代码是：
package reportmonitory;
import java.sql.*;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.swing.JRViewer;
import javax.swing.*;
public class monthlyreport extends JFrame {
Connection con;
Statement stmt;
ResultSet rs;
void showReport() {
try {
String host = "jdbc:mysql://192.168.10.11/rmcdb";
String uName = "root";
String uPass = "";
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection(host, uName, uPass);
stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
String reportName = "reports/finalreport.jasper";
java.io.InputStream is = this.getClass().getClassLoader().getResourceAsStream(reportName);
JasperPrint print = JasperFillManager.fillReport(is, null, con);
JRViewer viewer = new JRViewer(print);
viewer.setOpaque(true);
viewer.setVisible(true);
this.add(viewer);
this.setSize(1000, 1000);
this.setVisible(true);
this.setDefaultCloseOperation(HIDE_ON_CLOSE);
} catch (Exception ex) {
System.out.println("CAUSE: " + ex.getCause());
System.out.println("MESSAGE" + ex.getMessage());
System.out.println("LOCAL MESSAGE" + ex.getLocalizedMessage());
ex.printStackTrace();
}
}
public static void main(String args[]) {
new monthlyreport().showReport();
}
}
