you're there, few minor things:

you see login form data need send other username , password (e.g. __viewstate, __eventvalidation , more)? need retrieved dynamically. believe unique values sent when first go login form page.

so need is, instead of posting fixed values, need parse them first loginform received, set cookies first login form.

for more details i've written comprehensive tutorial on how login websites using jsoup here, believe lot.
