Hi Greg, in eclipse 3.4.x you can enable a warning on missing annotations, etc, under: Preferences / Java / Compiler / Errors / Warnings , Annotations and select what is ignored by default , but for the full workspace, without assigning it to a specific project.
Then a full rebuild is needed. Note that these warnings are not shown in the source, but i see them in the problems list ... but could be another eclipse settings. Bye
