Hi Giordano,
You’ve chopped off the root error in the stack trace below so it’s hard to help you with
your velocity error.
Thanks

Hi Vincent,
I've solved the "save files" problem with absolute paths and it works,
however I've another problem, this time with the Velocity macro inside a wiki page.
This is the exception that I've got:
org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for

You can find in the attachments the Tree structure of my wiki, pages inside "BSS
Rome" space are all terminal pages.
Thank you for your help,
Giordano.

Thanks Vincent,
I found everything I need but I got a nullpointer exeptioneverytime I use the
environment.getTemporaryDirectory() method in my code.
I thought it could be the component manager, so I've tried to inizialize it but I got
an error every time I call the method "initialize()", as suggested in [1] and
[2].
If you’re deploying your component inside an XWiki you don’t need to initialize the CM,
this is done for you by XWiki.
A NPE means you’re missing an @Inject and thus the Environment instance is null.
Could you show us your code?
Thanks
-Vincent
Any ideas why it is not working?
Thanks,
Giordano
