Distributing Java Application and files -


i have written java application talk blood machine. , posts data web server using oauth security , xml, , application works great.

but need distribute customers have these machines. program in .jar file , requires other .jar files in project/dist folder.

during execution uses little .png files displayed icons on screen, user can click etc.

i want how wrap of (including images) , distribute them either installer or can use web server.

what best way accomplish this, tried copy .jar , dist folder (as per instructions came out of netbeans) when run java -jar myfile.jar prints out text had ioexception because have not included .png files.

code png files: im using this:

try      {         databaseimage = imageio.read(new file("image/database.png"));         databasedisconnectedimage = imageio.read(new  file("image/database_delete.png"));      }      catch (ioexception ioe)     {         system.out.println("problem creating systray: "+ioe.getmessage()+" current working directory is: "+system.getproperty("user.dir"));     }

you have number of alternatives including following:

  • build installer installs relevant files on user's machine. can either write scratch or use commercial or open-source tool create installer. (installing on multiple operating system types gets complicated ...)

  • restructure application resources (e.g. images) fetched via classpath rather directly file system. create executable "uber-jar", exploding of dependent jars , resources, assembling files 1 tree, , jar-ing tree. (the jar made executable adding couple of entries manifest.)

  • create jnlp launcher application. works if end-user going able access website hosts application files, neatly solves problems of updating application, , ensuring user using up-to-date jvm.

which best? each alternative has pros , cons, , need work out best for you.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
