我创建了一个jDialog，其中包含一个表，3个jLabel和一个打印按钮。 当我单击那些按钮时，将打开一个jasper报告，该报告填充了一些mysql数据。它工作正常，但问题是我还想在没有mysql数据的jasper报告中显示3个jLabes数据。
我是CSE的学生，请帮我怎么可能？
这是我的打印按钮代码
// Report Display
this.dispose();
try {
//String report="F:\\My Practice\\Programming\\java\\DCM\\src\\dcm\\report.jrxml";
JasperDesign jd = JRXmlLoader.load("E:\\Java\\HBD-DHPM\\src\\Accounting\\cashBook.jrxml");
