Java - Open a PDF file from within the JAR in a Java window (JPanel, JFrame)

Question

I have a Java desktop application (a jar that will be used in a Mac OS .app and a Windows .exe). This Jar will contain a PDF file and I need to show this file in a Java Swing window. How is this possible? Can be done without any additional library, like ICEPdf?

Answer 1

使用此功能，您将使用操作系统已安装的默认PDF查看器

Desktop.getDesktop().open(new File(*path to PDF*));
