HttpClient, CSS validation

[Erik]

I want to have a Java program do an online validation of a CSS file at
http://jigsaw.w3.org/css-validator/validator

In Firefox, I can do

http://jigsaw.w3.org/css-validator/validator?text=h2{margin-left:233px;}

and I get an HTML page back, saying all is OK.

Now, how can I find out how to build a request from Java, with
HttpClient from http://hc.apache.org/httpclient-3.x/ ?
I try to send the CSS file over, which seems to work, but I only get
an HTTP error 500 back.

I do this kind of thing all the time using
http://mindprod.com/products1.html#HTTP

for example look at the code in
http://mindprod.com/products1.html#SUBMITTER
http://mindprod.com/products1.html#FILETRANSFER

You will need Wireshark
http://mindprod.com/jgloss/wireshark.html

to snoop on the communications between your browser and the website.
You then know precisely what you have to emulate.

see http://mindprod.com/jgloss/http.html
for background

also see
http://mindprod.com/jgloss/screenscraping.html#WEB

If you find this overwhelming, I will write a class to your specs for
$20.

There is another approach. I think the W3C people will give you the
source code for their validator. You could then exec it. The catch
is, it is probably written in C, and would require a version for each
platform.

That general approach can be made to work. Post the code which embodies
your specific approach (and i do mean *the* code - please don't post
snippets or paraphrases), and we'll see if we can see what's wrong with
it.
