The manual reads:

1.6.2 Selecting a Completion Method

The JDEE’s generic completion command, ‘jdee-complete’ delegates
completion to one of several specific completion commands supplied by
the JDEE or to a custom completion method that you supply. This allows
you to customize jdee-complete to use the completion method that you
prefer.

To specify your preferred completion method:

1. Type M-x jdee-complete-function RET

2. Select the completion command that implements the completion method
   you prefer.

3. If you selected Custom as your preferred completion function, enter
   the name of the custom completion function in the adjacent edit
   field, replacing the existing contents (ignore by default.).

4. Save your selection in your .emacs or project file.

Notice:

When I type M-x jdee-complete-function RET I am told by the mini buffer that there is "[No Match]" the function was removed or changed at one point and the manual was not updated.
