Implementing Crawler4j with Selenium in Java doesn`t work -

-

i'm trying use crawler4j simultaneous selenium website testing. after webpage crawled, selenium should start simultaneous test parameters got crawler. url should open or id's of search fields example. if use crawler4j alone works fine , can extract information need. if start test selenium predefined parameters url , id's works should. when put same code selenium crawler code exception. guess it`s maybe threat problem? nice if give me hint or me:

exception in thread "crawler 1" java.lang.noclassdeffounderror: com/google/common/base/function     @ mypackage.com.selenium.init(selenium.java:21)     @ mypackage.com.mycrawler.visit(mycrawler.java:57)     @ edu.uci.ics.crawler4j.crawler.webcrawler.processpage(webcrawler.java:351)     @ edu.uci.ics.crawler4j.crawler.webcrawler.run(webcrawler.java:220)     @ java.lang.thread.run(thread.java:722) caused by: java.lang.classnotfoundexception: com.google.common.base.function     @ java.net.urlclassloader$1.run(urlclassloader.java:366)     @ java.net.urlclassloader$1.run(urlclassloader.java:355)     @ java.security.accesscontroller.doprivileged(native method)     @ java.net.urlclassloader.findclass(urlclassloader.java:354)     @ java.lang.classloader.loadclass(classloader.java:423)     @ sun.misc.launcher$appclassloader.loadclass(launcher.java:308)     @ java.lang.classloader.loadclass(classloader.java:356)     ... 5 more

here code crawler:

public class mycrawler extends webcrawler {       private final static pattern filters = pattern.compile(".*(\\.(css|js|bmp|gif|jpe?g" + "|png|tiff?|mid|mp2|mp3|mp4"             + "|wav|avi|mov|mpeg|ram|m4v|pdf" + "|rm|smil|wmv|swf|wma|zip|rar|gz))$");  /** * should implement function specify whether given url * should crawled or not (based on crawling logic). */     @override     public boolean shouldvisit(weburl url) {         string href = url.geturl().tolowercase();         return !filters.matcher(href).matches() && href.startswith("http://");                                             }        /**      * function called when page fetched , ready processed      * program.      */     @override     public void visit(page page) {             int docid = page.getweburl().getdocid();             string url = page.getweburl().geturl();             string domain = page.getweburl().getdomain();             string path = page.getweburl().getpath();             string subdomain = page.getweburl().getsubdomain();             string parenturl = page.getweburl().getparenturl();             string anchor = page.getweburl().getanchor();              system.out.println("docid: " + docid);             system.out.println("url: " + url);             system.out.println("domain: '" + domain + "'");             system.out.println("sub-domain: '" + subdomain + "'");             system.out.println("path: '" + path + "'");             system.out.println("parent page: " + parenturl);             system.out.println("anchor text: " + anchor);             // here webbrowser should open don`t work             webdriver driver = new firefoxdriver();        driver.get(url);                  if (page.getparsedata() instanceof htmlparsedata) {                     htmlparsedata htmlparsedata = (htmlparsedata) page.getparsedata();                     string text = htmlparsedata.gettext();                     string html = htmlparsedata.gethtml();                     list<weburl> links = htmlparsedata.getoutgoingurls();                      system.out.println("text length: " + text.length());                     system.out.println("html length: " + html.length());                     system.out.println("number of outgoing links: " + links.size());                 }                  header[] responseheaders = page.getfetchresponseheaders();             if (responseheaders != null) {                     system.out.println("response headers:");                     (header header : responseheaders) {                             system.out.println("\t" + header.getname() + ": " + header.getvalue());                     }             }              system.out.println("=============");      }

i used httpcore-4.2.2 , httpclient-4.2.3. there must have been problem using selenium. after updated them latest release worked should. lost 1 week finding this.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
