Two possible ways of doing this:

  1. edit your menu settings from within your DM settings menu, or
  2. within IcedTea control panel, check appriopriate box that triggers showing "Open with JDK" in context menus. In KDE it looks moreless like this:


none of the above works

Hi! If using Ubuntu then open the terminal and type:

locate java.desktop

It should find few entries under /usr/share/app-install/desktop/, these are the files used to generate the desktop entries. If you don't get results try to update the mlocate database through the command updatedb. If you get some results the one you need is:


So open the mimeapps.list file in your profile:

leafpad ~/.local/share/applications/mimeapps.list

And add this line:


The format is simple: mime-type = app.desktop. Then if the option does not appear, create a shortcut in ~/.local/share/applications/:

ln -s /usr/share/app-install/desktop/openjdk-7-jre\:openjdk-7-java.desktop ~/.local/share/applications/.

And then it should work. If this does not help then you have to manually create a .desktop file, these are the contents of mine:

[Desktop Entry]

Name=OpenJDK Java 7 Runtime
Comment=OpenJDK Java 7 Runtime
Exec=cautious-launcher %f /usr/bin/java -jar


Hope it helps, bye!

thank you , it worked after creating the shortcut in ~/.local/share/applications/
