Launcher icons are stored in /usr/share/applications
. Go to your terminal and type: sudo nautilus /usr/share/applications
, then right click the application you want, select Properties and click the icon on the properties window. Now you can set it to any icon you want.
*edits
*here is an example .desktop file.
[Desktop Entry]
Name=Give me a name!
Comment=Explain me here!
Icon=/home/t32/t32.png
Exec=/home/t32/bin/pc_linux/t32marm -c /home/t32/config_usb.t32
Terminal=false
Type=Application
Categories=This is important, select a category that is present
StartupNotify=true
*use one of the following as category: Accessibility, Customization, Education, Games,
Internet, Office, System, Accessories, Developer, Graphics, Media, Other
. Exec is the command to run, Icon is an absolute path to where the icon lives. Usually you wouldn't need to alter anything else. You may keep this as a scratch and reuse.
*copy this to a whatever-you-name.desktop
file, edit as needed and put the file in the /usr/share/applications
directory. If paths are true, it will pop up in the gnome menu. I don't know if lucid had Unity
or gnome3
, but if it has, when you search it by the name you gave it, it will be visible in the unity lens
, gnome activities
thing. If you have gnome2
, it would be grouped under the corresponding category in the applications menu.
*And this kind of launcher are so cute that they are valid in GNOME, KDE and (probably) all others.

From your comment, it turns out that there is no icon defined in the
.desktop
file. You can use an icon "of your choice", and edit the line:to:
You will possibly have to log out and back in to make the change appear.
Note1
If you found your
.desktop
file in/usr/share/applications
, it is good practice to first copy it to~/.local/share/applications
and edit the local copy. After log out / in, the local version will "overrule" the one in/usr/share/applications
.Both Dash and the Unity Launcher will then use the local one.
Note2
You might want to look inside the application's directory (which seems to be
/opt/sqldeveloper
) if there is not already an appropriate icon to use./opt
is a typical directory where self-contained "all in one" applications can be located.
