Well, I've been looking through those 15 lines last two days.. I tried
Apache's HttpClient with same effect (I used FileEntity for body, not
multipart). I've seen many examples in Google which send post request.. My
code is just the same..
Hi.
I did some research, because I wanted to wrap up a number of recent
discussions on this forum.
Despite what you may wish and what you may have found in Google, I
believe that if you want to send a file, you have to do it with a
"multipart/form-data" content type. That is because it is the only way
to let the server know what kind of file your are sending, and how it is
encoded. The Apache HttpClient library will let you do that. I do that
in a couple of application, and I never had a problem with Tomcat 4 and
5. Have not tried it yet with Tomcat 6, but this is so basic that I
doubt there would be a problem.
Have a look here :
http://www.faqs.org/rfcs/rfc2616.html
Sections 9.5 (POST) and 9.6 (PUT) describe the two methods that allow
you to upload a file. But 9.6 is not applicable, since you are sending
this to a webapp, not directly to a URI.
There are also
http://www.faqs.org/rfcs/rfc2388.html
http://www.faqs.org/rfcs/rfc2046.html
http://www.faqs.org/rfcs/rfc2046.html
Then there is http://www.w3.org/TR/html401/interact/forms.html
which is the only document that I have found which describes a bit more
in detail how you should POST a file via HTTP.
Look at section
17.13.4 Form content types
Now, the funny part is that I don't find a corresponding
request-handling method on the server side for such a POST..
Not in the servlet specs, that is.
?
It seems that I need some more Googling myself.
