AW: [opencms-dev] Examples of news and navigation with jsp.

Mon Dec 1 09:13:01 CET 2003

Hi ,

Something like this (below) .... although here I am getting the news id
from a property. If you want to loop through all news items then get the
NewsChannelContentDefinition object. See the documentation for this
class, or search the mailing archive. Stuff has been posted on this
previously.

The other channels have nothing to do with the News modules and again,
if you search the archive ... Alex wrote some stuff on these.

There is currently no way to change the permissions on news channels.

All the best,

mark
