According to
http://sourceforge.net/project/showfiles.php?group_id=126011
the last release was 2006 so, I don't think that it's actively maintained anymore.
Too bad that veloedit doesn't work.
Ok, I tried it again and now it worked. Must have something to do with my installation.
So for me veloedit is the way to go :)
Next Edit:
On the next day, I got Eclipse exceptions again, when I started to use the veloedit editor. Now I'm just using a regular html/jsp editor to have at least some kind oh html syntax highlighting...
