Doing a form-based FILE-UPLOAD from inside a servlet

[DiscoStu]

Hello Everyone,

I have two tomcat servers, one running on the client machine and
one running on the server machine. I needed offline support for my
application, thats why I need tomcat on the client machine. Well, I
want to upload my reports to the server and I was thinking the HTML
form based upload would be nice, but I dont want the user to have to
select the file thats going to be uploaded. Is there any way to have
it upload a specific file rather then letting the user select a file?

Thanks (Maybe this question is better suited to an HTML newsgroup, but
java makes me happy)

Peace be unto you

Try value

type=file
Creates a file select control.
User agents may use the value of
the value attribute as the initial file name.

8. Security Considerations

It is important that a user agent not send any file that the user has
not explicitly asked to be sent. Thus, HTML interpreting agents are
expected to confirm any default file names that might be suggested
with <INPUT TYPE=file VALUE="yyyy">. Never have any hidden fields be
able to specify any file.

Note: Never have any hidden fields be able to specify any file.
However, I guess user agents might not deter the usage of the javascript submit() function
or the setting of the css visibility property of the containing element to invisible.


Have a good day.
