In addition, the path supplied by the browser is browser-dependent: some browsers provide the full path on the client, some only provide the filename.

No, the absolute path is not available and also completely irrelevant to
a web application because the absolute path as seen by the client who
uploaded the file may or may not be the same to another client who looks
at the uploaded data. Again, this is due to how file uploads via HTTP
work. The browser simply does not supply the information about the
absolute path, so the web application is unable to display this
information. The only way you would possibly get this kind of
information would be a java applet, but this is way off topic for this list.

OK, thanks for your response
if i understood well, there is no way to initialize the displayed path (the
problem is that the client want a default value, which must be display and
if the client make sumbmit i must make trt with it)
furthermore ,in the trt, i want the absolute path which i give as parameter
to other function
but in the formFile, i find only getFileName(), which gives only the name ,
not the absolute path
have you an idea how can i get the absolute path?

Hi,
short answer: This is not possible. This restriction is not imposed by
Struts but is instead due to a restriction of the <input type="file">
html tag, for which the value can not be prefilled or changed
programmatically. In our app we therefore have the pattern that when a
file is currently already uploaded, then we have a readonly display of
the file name and other statistics plus a link that reads "upload new
file" (or something similar). This link opens our upload page which the
user can then use to upload the file. Then the system goes back to the
original page with the new file's details.
HTH,

Hi,
A HTML input of type file can't have a default value. This is a security
issue.
