edited(adding jmenuitem in jpopupmenu)

table.addmouselistener(new mouseadapter() {         @override         public void mousereleased(mouseevent e) {             if (e.getbutton() == java.awt.event.mouseevent.button3) {                 system.out.println("right click");                 int r = table.rowatpoint(e.getpoint());                 if (r >= 0 && r < table.getrowcount()) {                     table.setrowselectioninterval(r, r);                  } else {                     table.clearselection();                 }                  int rowindex = table.getselectedrow();                 if (rowindex < 0)                     return;                 if (e.ispopuptrigger() && e.getcomponent() instanceof jtable ) {                     jpopupmenu popup = new jpopupmenu();                     jmenuitem item;                     popup.add(item = new jmenuitem("add"));                     item.sethorizontaltextposition(jmenuitem.right);                     item.addmouselistener(this);                     popup.add(item = new jmenuitem("delete"));                     item.sethorizontaltextposition(jmenuitem.right);;                     popup.setcomponentpopupmenu(popup);                     popup.show(e.getcomponent(), e.getx(), e.gety());                 }             }         } 

this jpanel not implement actionlistener...

have @ how write action listeners , how use menus , might become farmiluar how use actions

you can use jcomponent#setcomponentpopupmenu instead of using mouselistener , should making sure building uis within context of event dispatching thread, have @ initial threads more details

popup example

works fine me...

jtable table = new jtable(model);  jpopupmenu popupmenu = new jpopupmenu(); jmenuitem mi = popupmenu.add("boo!"); mi.addactionlistener(new actionlistener() {     @override     public void actionperformed(actionevent e) {         system.out.println("ah, ghost!");     } }); table.setcomponentpopupmenu(popupmenu);
