For RCP AUT's , a keyboard layout must be entered in the AUT configuration 3.7.2.4. Jubula installs German (DE) and English (US) as standard keyboard layouts.
If you require a different keyboard layout, you must create a mapping file for the new language -->Reference Manual and place it in the server/resources directory. You also have to put this mapping file into the RCP Remote Control plug-in of your AUT :
<RCPAUT>/plugins/org.eclipse.jubula.rc.rcp_<Version>/resources
