Jeba, You have probably upgraded your jde since you last modified your key bindings. This means the jde-keybindings in your .emacs file has a reference to an old function that no longer exists.
Customizations in your .eamcs can refer to functions that don't exist, but when you then edit those and save them in customize it checks that they are all valid. Remove the customization of jde-keybindings from your .emacs file (noting what changes you had made) and re-add them manually in customize after restarting emacs.
