I want to be able to open a file chooser dialog, from which I will be able to choose more than one file from the same dircetory. Similarly to the behavior that 'add attachment to gmail' provides.
Only I don't need to upload the files immediately through Ajax. the files that I chosed can be uploaded later when pressing on the submit button of that dialog.
The technologies that are available are:
html, javascript,, JQuery (only if needed) JSP, java
From previous research (and a quick Google search now), it appears that you can't do that solely with HTML/Javascript with one input selection. However, there are lots of Flash uploaders that will let you do this. But, since Flash is not one of your technologies listed, I'm not sure if you want to go that route...
