New to Java

i'm developing one project using the file operations implementations. I'm displaying the contents of the file in my jsp page. The first column i've putted a checkbox option and at last i've created the button. If i clicked that particular checkbox and then if i press the delete button then it should be able to delete the all check marked files from the directories.
Could anyone tell me how to do this in jsp. Is there any need for javascript or it can be done only through the jsp codings.
in advance thanks....
