This took some time (OK, it took me day and it was painful), so here are some hints :
- If you have uploaded the updatesite-runtime.nsf from openntf.org, you MUST sign all the plugins (Actions/Sign all).
- In order for the Web preview to work, you will need to manually copy the plugin and feature files found respectively in
C:\Program Files (x86)\IBM\Notes\Data\workspace\applications\eclipse
to
C:\Program Files (x86)\IBM\Notes\Data\domino\workspace\applications\eclipse\features - finally, when you read ‘restart http’ the command you want is
Restart Task HTTPnot
Tell HTTP Restart
And here are the most useful articles and ressources I found on the interwebs:
