*.java = svn:keywords=Author Date Id Revision;svn:eol-style=native
Complete list of keywords: Author, Date, Header, Id, Log, Locker, Name, RCSFile, Revision, Source, State.
Of course, you need to add a line for every file type you want to configure for a fine grained control over that. Otherwise use *.
This works for all files committed from now on. If you already have files in the repository, you need to tell SVN to add them too:
# Make sure that everything is up to date
> svn up
# Add keywords and commit
> svn propset svn:keywords "Author Date Id Rev" file_name
> svn commit -m "Adding Id and Rev property to all files"
