错误：

  

net.sf.jasperreports.engine.JRException：无法加载对象   位置：C：\ Users \ Juan Ortega \ Documents \ NetBeansProjects \Selección   de Aspirantes \ src \ Formularios \ Subreporte 1.jasper

保存所有内容的文件夹是C：\ Users \ Juan Ortega \ Documents \ NetBeansProjects \SeleccióndeAspirantes。里面的子文件夹和文件是：

  • 构建
  • DIST
  • nbproject文件
  • SRC
    • BD
      • ConexionMySQL.java
    • Formularios
      • Administrador.form
      • Administrador.java
      • Aspirantes.form
      • Aspirantes.java
      • Avisos.form
      • Avisos.java
      • ClaseiReport.java
      • Conexion.java
      • Principal.form
      • Principal.java
      • Reporte.jaasper
      • Reporte.jrxml
      • Subreporte 1.jasper
      • Subreporte 1.jrxml
      • Subreporte 2.jasper
      • Subreporte 2.jrxml
  • 的build.xml
  • MANIFEST.MF
  • MySQL Connector.jar

我清理并构建项目，以便其他用户可以使用它。当他们从控制台运行生成的Java可执行文件时，他们从上面得到错误。类ClaseiReport.java中的代码如下：

public class ClaseiReport {
private Conexion con = new Conexion();

public void reporte() {
    JasperReport reporte;
    JasperPrint reporte_view;
    try {
        URL  in = this.getClass().getResource("Reporte.jasper");
        reporte = (JasperReport) JRLoader.loadObject(in);
        reporte_view = JasperFillManager.fillReport(reporte, new HashMap(), con.getConnection());
        JasperViewer.viewReport(reporte_view,false);
        con.desconectar();
    }
    catch (JRException e){
        e.printStackTrace();
    }
}
}

我认为错误与文件Reporte.jrxml上的完整路径有关：

<defaultValueExpression><![CDATA["C:\\Users\\Juan
Ortega\\Documents\\NetBeansProjects\\Selección de Aspirantes\\src\\Formularios\\"]]></defaultValueExpression>

我不知道如何确保.jar在另一台计算机上使用它时找到子报告。我在论坛上看到了很多关于此错误的问题，但我无法弄清楚如何修复它。

下一个代码块包含在主报表（Reporte.jrxml）中。我应该在<defaultValueExpression>变量上更改什么？
