image - Change System tray Icon in java -

i want change system tray icon image application. did 2 things -

just changed url in default program -

final trayicon trayicon = new trayicon(createimage("images/graph.png", "tray icon")); 

second try -

image img = toolkit.getdefaulttoolkit().getimage("images/graph.png"); final trayicon trayicon = new trayicon(img, "application name", popup); 

the application launches in both cases no image shown. blank placeholder. doing wrong ?

images/graph.png not valid url image located in jar. hence, guess img null on second try.

i suggest way :

//get url method class.getresource("/path/to/image.png") url url = system.class.getresource("/images/graph.png");  //use image image img = toolkit.getdefaulttoolkit().getimage(url);  final trayicon trayicon = new trayicon(img, "application name", popup); 

you shall ensure images/ in classpath.
