java - JavaFX WebView: Start Program, Input Data, Serve and Display Local HTML -> Refresh Data = Refresh WebView -


i need able open application, input data via textfields, send said data through freemarker , generate html, display in webview.

here i'm falling off.

i have working cannot, life of me, figure out how refresh webview display new current html doc after data input , rewrite.

it's overwriting file fine, if close , reopen, re click button, webview shows new data.

i'm sure issue i'm using getclass().getresource(string):

url link = getclass().getresource("emailsigtest.html"); engine = webview.getengine(); engine.load(link.tostring());

how can thing change dynamically, i.e:

1. input data 2. write file 3. refresh webview reflect new html doc

where need write , read file , make happen?

i have tried engine.reload(); reload webengine... nothing.

i have tried adding actionevent , .reload()... nothing.

full source below:

public class signaturegenfxmldoccontroller implements initializable {     private string firstname, lastname, directline, title, cellphone, lineone, linetwo;     boolean social = false;     @fxml private textfield txtfirstname, txtlastname, txtdirectline, txttitle, txtcellphone;     @fxml private checkbox chksocialicons;     @fxml button btngenerate;     @fxml webview webview;     @fxml webengine engine;      @fxml private void handlebuttonaction(actionevent event) throws interruptedexception {         system.out.println("you clicked me!");         firstname = txtfirstname.gettext();         lastname = txtlastname.gettext();         directline = txtdirectline.gettext();         title = txttitle.gettext();         cellphone = txtcellphone.gettext();          writehtml();         readhtml();     }      @override     public void initialize(url url, resourcebundle rb) {      }     private void writehtml(){         // configurae freemarker     configuration cfg = new configuration();     try {         // load template         template template = cfg.gettemplate("src/signaturegen/template.ftl");         map<string, object> data = new hashmap<string, object>();              data.put("fname", firstname);             data.put("lname", lastname);             data.put("title", title);             data.put("dline", directline);             data.put("social", social);              writer console = new outputstreamwriter(system.out);             template.process(data, console);             console.flush();             // file output             writer file = new filewriter (new file("build/classes/signaturegen/emailsigtest.html"));             template.process(data, file);             file.flush();             file.close();         } catch (ioexception e) {             e.printstacktrace();         } catch (templateexception e) {             e.printstacktrace();         }     }          private void readhtml(){         url link = getclass().getresource("emailsigtest.html");         engine = webview.getengine();         engine.load(link.tostring());     } }

as discussed in this question, reloading same url in webview not work.

what might want try delegating reload javascript in page itself. define function in page:

function reloadme() {   location.reload(); }

and call function java:

private void readhtml(){     url link = getclass().getresource("emailsigtest.html");     engine = webview.getengine();     engine.executescript("reloadme();");  }

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

ruby on rails - Seeing duplicate requests handled with Unicorn -

(6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
