Java APIs

Hi,

Hope this is the right forum for the question.

I’m able to successfully upload a file via a website. Now I want to automate this process by using a HttpClient to send a MultiPart post request. The problem is that the requests kept getting rejected by the server due to "corrupt form data” and that’s all the info I can get from the server.

That leaves me to compare the requests sent from the web browser (good) and from my Eclipse (bad). I see some differences but can’t tell what might be causing the issue. Hopefully the experts in this forum can offer some help. Thanks.

Here’s the request sent from Eclipse (rejected):

Header part:

Here’s the request sent from the browser (accepted)

Any suggestions would be greatly appreciated. One thing I noticed is that the browser sent the lines below in the beginning of the body and HttpClient sent them as part of the header. Could that be a problem? If yes, how should I fix the behavior?
