Save a file and then open it using javafx -

-

i have file stored in project directory. make few changes , save using filechooser saved dialog box. after saving want file automatically opened in system. succeeded in saving file not getting how open automatically without user choosing open dialog box. code saving file written below.

string input = "";             try {                 outputstream outstream = null;                 ipfile = thread.currentthread().getcontextclassloader().getresourceasstream("upgradeworkbench/resources/ip_template.sh");                 stage stage = new stage();                 stage.settitle("save");                 byte[] buffer = null;                  buffer = new byte[ipfile.available()];                 ipfile.read(buffer);                 filechooser filechooser = new filechooser();                 filechooser.setinitialfilename("ip_template");                 filechooser.getextensionfilters().addall(                         new filechooser.extensionfilter("development file", "*.sh")                 );                 filechooser.settitle("save file");                 file file = filechooser.showsavedialog(stage);                 if (file != null) {                     outstream = new fileoutputstream(file);                     outstream.write(buffer);                     bufferedreader reader = new bufferedreader(new filereader(file));                     while ((line = reader.readline()) != null) {                         input += line + system.lineseparator();                     }                     input = input.replace("logpath=$logpath", "logpath=");                     input = input.replace("procfilename=$procfilename", "procfilename=");                     input = input.replace("binfilename=$binfilename", "binfilename=");                     input = input.replace("reportfilename=$repfilename", "reportfilename=");                     input = input.replace("formfilename=$formfilename", "formfilename=");                     input = input.replace("custom entries made java code here", "file created");                     bufferedwriter writer = new bufferedwriter(new filewriter(file));                     writer.write(input);                     writer.flush();                     writer.close();                     reader.close();                 }             } catch (ioexception ex) {                 system.out.println(ex.getmessage());             }

please me how can open file saved in local drive.

p.s: don't want use filechooser.showopendialog(stage) open dialog box , choose open file. want open automatically.

for javafx solution, use hostservices:

// gethostservices() application method. may // need call in application subclass , expose // rest of application somehow, depending on // application structure: hostservices hostservices = gethostservices() ;  hostservices.showdocument(file.touri().tostring());

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana
