If there are many of these, I usually import them all in one go
(jde-import-all).

It would be really nice if there was a way to have a general
"quick-fix" mechanism in jdee.  Perhaps something where each quick fix
defined a regexp to match on the current compilation error line to
determine whether it should be active, plus an action to take if the
user opts for that quick fix.  Jdee would evaluate the set of active
quick fixes whenever the currently selected error changes (updating a
quick-fix menu).  We could add to the suite of quick-fixes over time,
and users could define their own.

E.g:
 add throws to current method
 add catch block to existing try
 add try-catch block to selected region

(Presumably the regexps would be dependent on whichever compiler the
user is currently using, so there may need to be different lists for
ecb vs javac vs jikes etc)


Actually, searching through the archives, it seems Kai Grossjohann had
started an initial version of this in 2004...


(/me fervently waits for when jdee gets moved to sourceforge so we can
make some progress on this)
