NotSerializableException during serialization of JFrame. Make `JFileChooser` transient to serialization

Question

I wanted to serialize my JFrame but unfortunately I get NotSerializableException . I thought that the JFileChoosers are the reason so I added transient modifier to them: transient JFileChooser fc = new JFileChooser(".");

And they are because removing them removes the problem but I need use JFileChooser how to make it really transient to serialization?
