File 'MOVE' Operation In ADF App.

Question

Hi All,
We have a requirement where using ADF App, we need to move a file from one location to another.
I tried using inputFile component and observed that using this I can copy file but cant delete the original file from source directory.
Do we have a component that does it?
I was also looking for a component like File Chooser of Java Swing so that I can do that in Java but cant find any such component as well.
How can I implement this in ADF app?
Thanks.

Mohammad is right.
Some more info about this might help you understand what is going on:
UploadedFile don't return a File but a wrapper class which give you access to the client file name and a stream object which contains the data send from the client. Depending on the size of the data send this stream resides in memory or is a file in the upload temp directory. The UploadedFile is only valid in the request you are working on, so saving the UploadedFile in a bean won't work as the stream is closed automatically. In this case you can only get the client file name but get null for the stream.
If you need the data longer then the request you are working on you need to copy the stream content into a temporary file or the DB and save the path and name to the file or PK to the db row for later access.
Now if you store the file temporarily you should delete the file if you don't need it any longer. This can be done using the code shown in the other thread. As you have saved the path and name to the temp file this should not be a problem.
