java - Error in crawler JMeter -

i have problem crawler test (spidering) in jmeter, have native code in java not work because need send parameter in post called javax.faces.viewstate

i need circumvent parameter, leave code in java , based on opinion more feasible crawler (spidering).

enter image description here image error in jmeter

public static void main(string[] args) {      try {          connection.response loginform = jsoup.connect("http://appware-sst.com/elegancia-ejecutiva")         .method(connection.method.post)                 .useragent("mozilla/5.0 (macintosh; intel mac os x 10_9_2) applewebkit/537.36 (khtml, gecko) chrome/33.0.1750.152 safari/537.36")          .execute();          document document = jsoup.connect("http://appware-sst.com/elegancia-ejecutiva/php/inicio_admin.php")         .data("user", "admin")         .data("password", "12345")                                    .cookies(loginform.cookies())         .post();              system.out.println(document);       } catch (exception e) {         system.out.println(e);     }  } 

looking regular expression don't think need ! in it.

also depending on server response may in multi lined, having other tag in between name , value, etc. recommend getting value using xpath extractor instead, relevant configuration be:

• reference name: meaningful, i.e. viewstate
• xpath query: //input[@name='javax.faces.viewstate']/@value

jmeter should fit better supports cookies, headers, cache, reporting. out of box, can use http(s) test script recorder building test skeleton.

you may find how spider site jmeter - tutorial useful can build crawler using html link parser test element only.
