Hello Vadim...
If you might explain the upload functionality ...
1. Form with multipart data is submitted to upload.xsp
2. The form parameters have to be processed. I changed the form
variable
name from uploaded_file to files and still it works.
3. If I have to do additional processing like throw error if the file
exists or the file needs to be stored in a specific pattern say
$upload_directory/date/user/filename_uniqueId. How can I
customize
it.
Look into the source. Start with CocoonServlet:
HttpServletRequest request =
RequestFactory.getRequestFactory(requestFactoryClass).getServletRequest(
req,
CocoonServlet.SAVE_UPLOADED_FILES_TO_DISK,
this.uploadDir,
CocoonServlet.ALLOW_OVERWRITE,
CocoonServlet.SILENTLY_RENAME,
this.maxUploadSize);
4. If there are additional form elements, how do I process them.
5. Where is the upload functionality being invoked.. Its kind a vague
(for my intellect).
From the servlet, see line(s) above.
Vadim
Thanks in Advance,
Chiths

RE: Vadim : RE: XSP Upload example - I do not understand
Thanks a million
I understand it now...
Let me try to clarify
1. Upload directory is read from init parameter. Hence it is kinda fixed
.
2. We do not get the control of uploaded files.
As soon as the Cocoon gets a request. The request is processed
for Multipart request processing. Is this how it has to be processed ?
The only way to change this is to provide my own version of multi-part
request processing factory. However, the problem is that you can have
utmost one kind of behaviour.
3. In my implementation, I need to store the files in different
directories, depending upon the type of files uploaded. How do you
suggest I go ant it...
Thanks in advance,
