I have a Java GUI application from which another java GUI application is invoked using reflection and loading. It works fine the only problem faced is, on closing the JFrame of invoked application the Main GUI application frame also closes. How can I prevent the main application (frame) from closing??
I cannot change the defaultCloseOperation of the invoked application, However a change to the main application can be made. Does it have any thing to do with threads??
This is my applications code that executes a target application
