Thanks for the prompt reply!

Actually I'm not using multi-part formposts. Just a regular POST with one
form and three fields with data.

I might be confused here then as to the diff between regular posts and
multi.

> You mean if you fill in the data with a browser and press submit? Are you

Yes, I have an .html with a form inside and then I press submit. No, it's
not a multi-part form as far I can see. It's just this:

<form method="POST"
action="http://anibaltest1/SeriesMover/SeriesMover.SeriesMoverServlet">
<INPUT type="hidden" name="action" value="getSeries"">

<INPUT TYPE="submit">
</form>

I'm sending only one field of the form here and I get it ok from the
servlet. When I try curl I don't get it at all.

Yes, my mistake. I cut/paste code from the function returning post and
assigning it to postData. So, yes I use the correct pointer.

Well, the output from Perl is that it gets the fields and their values. With
curl is says that it didn't receive anything.

It's just at the very beginning when I get the values out of the request. If
I hit the servlet with the HTML POST from the HTML web page it just shows
the fields and their values. With curl it says that there are no
fields/values.

Not sure if I'm using multipart formpost here. I can post the whole code if
you want. I'm getting desperate to get this fixed. Any help will be greatly
appreciated. I could put the servlet up on the Internet as well, so that you
can hit it with curl if you want.

Allright, well let me know otherwise.

Thanks, looking forward to getting to the bottom of this one,

I take it you mean multi-part formposts then. This is not the same as a
regular post.

You mean if you fill in the data with a browser and press submit? Are you
making that form a multi-part one then?

It is possible that curl issues the posts somewhat differently. I can't tell
for sure.

I guess you meant 'post' and not 'postData' in the latest line here,
otherwise I can see why this doesn't work...

Well, if you make this test again using one post with curl and then one with
lynx that you say works, you can compare the perl outputs and check for
differences.

Can't you make your servlet let you know exactly when in the flow it stops
understanding the input?

Not that I know of. Others have used the multipart formpost feature
successfully. I have too. I have test cases for it in the test suite proving
that it works at least partly.

> I can post the servlet code if you're interested.

Personally, I'm a java cluebie and so I wouldn't really know what to do with
it.
