include external jar into your own exported jar

One problem that almost java guys have is create jar with external jar include. In eclipse it has export function to export project but there's no way to add external jar with this method. Today I found one solution, the project Fat Jar Eclipse Plug-In can take care this problem.
Installation is just unzip it to eclipse folder then restart eclipse in shell or command line with this command "eclipse -clean". Now your eclipse already have fatjar plugin. To use it export the project, from your package explorer, right click on your project and select "Export...". You will get "Export Dialog"[see pic], choose Other->Fat Jar Exporter. From here you will know what to do next.:)
