Read folder contents and upload

Question

The following is what I am trying to do. I have already done Items 4 and 5.
I really appreciate if you can help me to find out the examples or documents that can achieve the functionality specified in 1,2 and 3.
1.     We are scanning and storing the images (.tif) in our server (application server or some other network location)
2.     When user logins in, I would like to show the list of all the images that are available in the specified location.
3.     User should be able to select the desired image and should be able to view the image.
4.     User will assign unique identification to each image and save the image to the database.
5.     User should be able to review the saved image at any time.

Answer 1

Do you need help with 1, seems like this is outside of Oracle entirely.
Assuming you figure out number 1 you have probably two options for 2 and 3. One is to embed a java file picker object like the one they use in the facebook photo albums application.

Another option is to make the directory used in 1 available to the database as a directory object. Then you can use the techniques presented here to display the file names.

You could allow the user to pick the file and then load it from file use the DBMS_LOB.LOADFROMFILE procedure to get it into the database as a blob. This could bypass your need for number 4. In fact you could just load the files into BLOBS at will for the user and never really store them in the database.
Hope this gives you a little direction. I think the main issue here is access to those files, the direction you take depends on if it is something the user will need to do through the OS or the database will need to do through a directory object.
