JAR doesn't work with Absolute Layout
问题 I have developed a swing GUI for my program using the NetBeans form editor. I used the AbsoluteLayout so that I could click and drag components to wherever I needed them to go on the frame. The problem is that when I try to run the executable JAR file that I made for the program, I get the following error: java.lang.NoClassDefFoundError: org/netbeans/lib/awtextra/AbsoluteLayout ...Exception in thread "main" All of the GUI code was written for me by NetBeans so I'm not sure what the problem is
