    public static final string logout_icon = system.getproperty("user.dir") + "/resource/com/talan/launcher/ui/icon/logout_icon.png"; } 

as u can see listener :

 public void initactions(){     bt_connexion.addactionlistener(new loginactionlistener()); }  private class loginactionlistener implements actionlistener {      @override     public void actionperformed(actionevent e) {         //system.out.println("***"+e.getactioncommand());         // displays same event           controller.checklogincreditsredirect(txt_user_name.gettext(),txt_password.gettext());      }  } 

and class maincontroller within class alfrescologinframe @autowired :

  @component     public class maincontroller {     @autowired      private isessionrepo sessionrepo;     @autowired     private wrongalfrescocreditsdialog wrongalfrescocredistdiag;        public maincontroller() {         }      public void checklogincreditsredirect(string login, string password){             checklogincredits(login, password);            if(sessionrepo.isvalid()){                //this sop executes twice                system.out.println("logged in !");             }else{              //also sop executes twice                system.out.println("not logged in : wrond credit !");                wrongalfrescocredistdiag.risewrongcreditspanel(alfresco_loginframe);            }        } } 

so checklogincreditsredirect(string login, string password) method called twice. think it's spring issue, appreciated guys?

you call initactions() twice yourself. once constructor , once halfway initcomponents method

next time have problem this: try debugging adding new exception().printstacktrace(); in method accidentally gets called twice
