javaagent sa da stiahnut na githube(aj ako binarka). Ak napriklad spustim jdownloader, WM_CLASS property hlavneho okna je podla vypisu programu `xprop’ takato:  WM_CLASS(STRING) = “sun-awt-X11-XFramePeer”, “jd-Main”. Avsak, ked spustim jdownloader spolu s javaagentom, WM_CLASS sa zmeni na toto:  WM_CLASS(STRING) = “sun-awt-X11-XFramePeer”, “JDownloader”. Teraz uz panel nevytvori novu ikonku programu, ale spravne sparuje okno aplikacie so spustacom. Jdownloader staci spustit takto:

java -javaagent:<path_to_agent.jar>/agent.jar=JDownloader -jar /home/<user>/.jd/JDownloader.jar

Takto teda vyzera upraveny .desktop subor v ~/.local/share/applications/:

[Desktop Entry]
Name=JDownloader
GenericName=Download Manager
Comment=Java based download manager, that also handles one-click-hosters
Exec=java -javaagent:/home/cinan/system/misc/agent.jar=JDownloader -jar /home/cinan/.jd/JDownloader.jar
StartupNotify=true
Icon=jdownloader
Type=Application
Categories=Network;

Podobne som vyriesil aj problem s netbeans, aj ked riesenie je ovela menej elegantne. Spustil som netbeans z terminalu, vo vypise `ps aux’ som nasiel kompletny prikaz, ktorym sa spustil netbeans, skopiroval ho, upravil (vlozil donho javaagent prepinac) a ulozil ako novy .desktop subor. Takto to vyzera:

Tento spustac ignoruje nastavenia v /usr/share/netbeans/etc/netbeans.conf.

Uprava .desktop suboru

Panel Docky som musel naucit, ze spustac prehliadaca chromium a jeho otvorene okno je ten isty program, a teda aby nevytvaral novu ikonu beziaceho okna. Povodne bola WM_CLASS property takato: WM_CLASS(STRING) = “chrome”, “chromium-browser”. Upravil som teda .desktop subor, presnejsie som pridal zvyrazneny riadok:

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Comment=Browse the World Wide Web with Chromium
Name=Chromium
Categories=Application;Network;
Exec=chromium-browser %U
Icon=product_logo_48.png
StartupNotification=false
StartupWMClass=Chrome
Terminal=false
TryExec=chromium-browser
Type=Application
X-MultipleArgs=false

Teraz je po spusteni WM_CLASS nasledovna: WM_CLASS(STRING) = “chrome”, “Chrome”, a panel sa sprava tak, ako sa od neho ocakava.

Dost podstatne je aj to, aby panel vedel, ze ma pouzivat ten spravny .desktop subor. Ak sa ulozi do adresara ~/.local/share/applications/, tak gnome-shell v zozname aplikacii uprednostni prave subory ulozene v tom adresari. Spustace v Docky som rucne upravoval cez gconf-editor v /apps/docky-2/Docky/Interface/DockPreferences/Dock1.
