Help: deleting package roots in eclipse broke svn

I've a number of Java Eclipse projects organized in the usual fashion:

        workspace
                project1
                        src
                                edu
                                        virtualschool
                                                ...
                project2
                        src
                                edu
                                        virtualschool
                                                ...
Each project is checked into subversion in the usual fashion, as
separate directories.

Problem is, the edu and virtualschool package directories showed as
empty in eclipse so I deleted them in the package browser, not
thinking of the fact that subversion sees them as directories, not
java packages, and expects to find a .svn directory there. So
checkins fail with Working copy ...workspace/project1/src/edu not
locked errors.

How to recover from this self-inflicted wound?
