Hello developers,
I've been experimenting a little bit into running things in the background on our
xwiki 3.5: as part of a velocity delivered page, I am calling groovy code. That code
launches a thread in the background which runs for 1000 seconds checking if it can:
- use the context's toString
- call context.getContext()
- use the xwiki object that was passed around
My current conclusion is that context.getContext() fails (with an NPE trying to check
programming rights) but others work.
Is this the intended behavior?
Is there a way for me to get another context to run in the background?
You need to set up the correct environment in your thread as otherwise all bets are off
:)
We do that in lots of places; just to name a few:
* The main Servlet thread
* Stats
* Lucene Updater and Rebuilder
* Linkchecker
* IRCBot thread
In the future I'd like to have common initialization code that can be easily reused.
We have a bit of this already with AbstractXWikiRunnable which are extended by Lucene
Updater and Rebuilder threads for example.
