java - Making handleFileupload with parameter to share the methode -


i'm using fileuplod primefaces. have 3 buttons. every button responsible uploading file. first steep use 3 methods on bean upload every file. there way make same method types? every file has own directory.

<h:form enctype="multipart/form-data"  style="height:125px;width:75px;">                     <p:fileupload  auto="true"                     fileuploadlistener="#{composantbean.handlefileupload(???,1)}"                    sizelimit="2097152"                    label="choose"                    allowtypes="/(\.|\/)(pdf)$/"                    description="images"/>                 </h:form>

on managed bean, i'm thinking of solution:

  public void handlefileupload(fileuploadevent event,int i) {         string lienpdn =destination+"pdn\\"+filenameutils.getname(event.getfile().getfilename());         file result = new file(lienpdn);          try {                fileoutputstream fileoutputstream = new fileoutputstream(result);                byte[] buffer = new byte[buffer_size];                int bulk;                inputstream inputstream = event.getfile().getinputstream();                 while (true) {                    bulk = inputstream.read(buffer);                    if (bulk < 0) {                        break;                        }               fileoutputstream.write(buffer, 0, bulk);              fileoutputstream.flush();              }            fileoutputstream.close();           inputstream.close();           facesmessage msg = new facesmessage("succesful", event.getfile().getfilename()+ " uploaded.");           facescontext.getcurrentinstance().addmessage(null, msg);           selcetitem.setlienpdn(lienpdn);           } catch (ioexception e) {                          e.printstacktrace();                         facesmessage error = new facesmessage(facesmessage.severity_error,"the files not uploaded!", "");                         facescontext.getcurrentinstance().addmessage(null, error);                         }                }

i think better way might implements 3 handlefileupload() methods. each can handle unique code (e.g. passing right filepath). there can call private void wrapupupload(string path, (...)).

most of keeps code readable. if prevents need changing default implementation of handlefileupload().

e.g.: make sure replace 1, 2, 3 meaningful

void handlefileupload1(fileuploadevent event) {      string path = "/uploads/1/";     wrapupupload(path); }  void handlefileupload2(fileuploadevent event) {      string path = "/uploads/2/";     wrapupupload(path); }  void handlefileupload3(fileuploadevent event) {      string path = "/uploads/3/";     wrapupupload(path); }  private void wrapupupload(string path, (...)) {     // upload file }

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

java - Are there any classes that implement javax.persistence.Parameter<T>? -

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
