How to Login in a JSF page using java -

-

i'm trying login in .jsf intranet page, here part of it:

     <form method="post" action="j_security_check" name="loginform" id="loginform">                 <input name="j_username" type="text" class="textbox" maxlength="30"/>                 <input name="j_password" type="password" class="textbox" maxlength="30"/>                 <input type=submit value="enter" class="button">                 <input type=submit value="exit" class="button">     </form>

i've searched , tryied @ java, didn't worked, same page result:

            httppost post = new httppost("http://xxxx/login.jsf");                 list <namevaluepair> parameters = new arraylist <namevaluepair>();                parameters.add(new basicnamevaluepair("j_username", "92232776"));                parameters.add(new basicnamevaluepair("j_password", "(7110oi14)"));               urlencodedformentity sendentity;              sendentity = new urlencodedformentity(parameters, http.utf_8);              post.setentity(sendentity);                 httpclient client = new defaulthttpclient();                httpresponse response = client.execute(post, httpcontext);                 system.out.print(convertinputstreamtostring(response.getentity().getcontent()));

(i'm using httpcomponents-client-4.2)

what need login in page? there need code button "send"?

thank guys.

the login information stored in session. session backed cookies. need maintain cookies across requests. basically, need pass retrieved set-cookie response header on every subsequent http request in same session long cookie valid.

in httpclient, need prepare cookiestore set in httpcontext in turn pass on every httpclient#execute() call.

httpclient httpclient = new defaulthttpclient(); cookiestore cookiestore = new basiccookiestore(); httpcontext httpcontext = new basichttpcontext(); httpcontext.setattribute(clientcontext.cookie_store, cookiestore); // ...  httpresponse response1 = httpclient.execute(method1, httpcontext); // ...  httpresponse response2 = httpclient.execute(method2, httpcontext); // ...

please note j_security_check login step not related jsf, applies every other java servlet based login form well. once intend submit real jsf form created <h:form>, you'd need take lot more account. head more detailed answer then: how can programmatically upload file website? whilst treats uploading of file programmatically through jsf form, basic principles submitting jsf form same (certain hidden input fields have taken account , on).

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
