Yes. I try following that information, but got many errors.
It's not a step by step guide. Also, they don't go over the changes and where.
In addition, one can't make a new guess account, post anything, or email to anyone
there. I tried to email to Rafael, but got no answer.
The JForum team basically seems to have abandoned JForum 2.x (including the online help forums) and is concentrating on JForum 3. So I doubt you'll get any help in doing this, nor would I advocate it because the code base is obsolete. Maybe they'll let you in on the JForum 3 prerelease if you promise to make it work on Oracle.
