i try converting jsoup , no luck. tried using headers, , using headers along pagenumber, scheduledrundate, etc. passed. both attempts return org.jsoup.httpstatusexception: http error fetching url. status=500. here code i'm attempting:

document pagedoc = jsoup.connect("mysite/campaign/list")                 .cookies(logincookies)                 //.header("cookie",cookielist)                 .useragent("mozilla/5.0")                 .referrer("mysite/campaign")                 //.data("username", username)                 //.data("password", password)                 //.followredirects(true)                 .header("accept","*/*")                 .header("accept-encoding","gzip, deflate")                 .header("accept-language","en-us,en;q=0.8")                 .header("connection","keep-alive")                 .header("content-type", "application/json;charset=utf-8")                 .header("host","mysite")                 .header("origin", "mysite")                 .header("referer","mysite/campaign")                 .header("user-agent","mozilla/5.0 (windows nt 6.1: wow64) applewebkit/537.36 (khtml, gecko) chrome/48.0.2564.97 safari/537.36")                 .header("x-requested-with", "xmlhttprequest")                 .header("__requestverificationtoken", pagetoken)                 .header("content-length", "165") //not sure if needed. if is, no idea how                 .data("pagenumber","2")                 .data("sortcolumn", "scheduledrundate")                 .data("sortascending", "false")                 .data("pagesize", "20")                 .data("collectionsize", "308")                 .data("selectedaccountid", "1")                 .data("searchterm", "")                 .data("showinactive", "true")                                .ignorecontenttype(true)                 .post(); 

i can confirm tokens correct. when comment out .header("x-requested-with", "xmlhttprequest") receive general error page (this expected) know i'm connecting, when leave in 500. can confirm "mysite" links correct, have remove them per company. i'm not sure if , how need add pagenumber, sortcolumn, sortascending etc. jsoup blindly added them data parameters shown above.

try remove header("content-length", "165") , .header("content-type", "application/json;charset=utf-8"). jsoup can add them you.

try use formelement also. see formelement example.
