Once you create a new Java (or any other file for that matter) under Eclipse it is quite convenient to add SVN header info upon comit automatically. This is done by adding a new file named "config" - e.g. in ~/.svn/settings/conf/. Then add the following information to the file:

enable-auto-props = yes

* = svn:keywords=Author Date Id Revision

Next, in Eclipse go to Windows > Preferences > Team > SVN and set the "Configuration location" to "Use directory", and simply browser to the configuration directory you just created (you select a dir, not a file!).
