Re: [xwiki-users] Not able to read attachments from server thread

2014-11-13 Thread Thomas Mortagne 
That's probably because you don't properly initialize your thread
(initialize an ExecutionContext and stuff like this). You can use
org.xwiki.context.concurrent.ExecutionContextRunnable to help with
this. Also to get a proper XWikiContext it's usually better to use
ProviderXWikiContext (either by injecting it or by using
XWikiContext#TYPE_PROVIDER as role type).

 Hi,
 I created a Macro in xwiki.
 In this macro a server process is started that tries to read attachments.

 This is the code:

Re: [xwiki-users] Not able to read attachments from server thread

2014-11-12 Thread Marius Dumitru Florea 
Btw, you should take a look at the Job Module
http://extensions.xwiki.org/xwiki/bin/view/Extension/Job+Module which
provides a clean way to perform, in a background thread, tasks that
access the XWiki model.

Hope this helps,
Marius
