java-获取用户选择上传文件的完整路径

Question

I am trying to create a simple screen where the file selected for upload by the user is assigned to a file variable.

Google Data APIs have a class "MediaFileSource" which uses "File" to store a file. Given below is code to assign an image file to a MediaFileSource object.

MediaFileSource myMedia = new MediaFileSource(new File("/home/liz/puppies.jpg"), "image/jpeg");

What I want to do is, ask the user to specify an image for upload, and then assign that image(chosen by the user using my web app) to the MediaFileSource variable. I just need the full path to that image (which was chosen by the end user) to assign it to a MediaFileSource variable.

What is the best way to do this? I plan to create the above functionality in a java web application on Google App Engine.

You can't get the full path on the user machine, only the file name.
It's for security reason and its not related to Google App Engine.
