we would like the user to be able to pick a file from native file system and drag & drop it to our application icon and have it uploaded to server

We have an existing java desktop application which starts, when user click on our application icon (placed on desktop) OR double click on executable(.exe). It opens the frame which allows user to select the file from native file system and uploads it to the server.

Now we would like to facilitate user, that he can pick a file from windows explorer and drag it to the "shortcut / Application icon" & drop it on the "shortcut / Application icon" on the desktop. This would start the uploading of that file on the server.

we need to capture the action of "drop" and launch on shortcut.. which may be completely not related to java, it can be very generic to any application.

We are using JSmooth to build an executable from jar and NSIS for installer purpose. I would like to know..

How we can launch the application if user drops local file onto the system icon ? How we get the absolute path of file name which has been dropped onto the开发者_如何学运维 executable ?

Dragging and dropping a file onto a executable (or a shortcut to an executable) will result in Windows passing the file name along to the executable as the first command line parameter. If the file name contains spaces, then the file name will be quoted.

You can then retrieve this file name from the args parameter passed to your main method and do what you need to do from there.

I suspect that Linux and OS X will behave in a similar fashion.
