Hi,
I'm wondering if it's possible to do a sequential file upload.
The situation is the following:
1. I make a simple file upload -
descriptor.dsc - to a HttpServlet - this works fine!
2. The
Servlet analyzes this file - it deals with a descriptor file which contains path infos of the LOCAL file system, belonging to the same project (also this works fine, the Servlet lists all files described in the uploaded descriptor file)
3. The user now has the possibility to choose which files (of the local file system) have to be uploaded now (realized with checkboxes)
4. That's my issue: I'm searching for a possibility to upload automatically all SELECTED files by the user.
To give an example, let's have a look at the local filesystem:
c:/project/descriptor.dsc
c:/project/unit1/image1.img
c:/project/unit1/image2.img
c:/project/unit2/image3.img
c:/project/unit2/image4.img
c:/project/unit3/image5.img
Due to the fact that most browser satisfy the security restritions, it's unlikely to get the file system infos (in our case: "c:/project") when I upload the file "descriptor.dsc" (which points to image1 ... image5).
Now it seems unpossible to tell to my routine something like "take the directory 'C:/project' and upload all files under unit1, unit2, etc.".
My Servlet thus only displays the relative file system, like
unit1/image1.img
unit1/image2.img
unit2/image3.img
unit2/image4.img
unit3/image5.img
In any case, if the user chooses for example "image1.img" and "image3.img", I would like to perform an automatic file upload, without having to choose such files manually by the html file input control. But I fear it's not possible, for security reasons, is it correct?
if there's a workaround, please let me know.
Without Flash, perhaps with Ajax oder even
Java applets.
Many thanks in advance.
