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

Hi users,
Thanks for your answers, anyway it wasn't a String problem, and also change
to GET doesn't produce anything. Maybe I've found my problem, when I start
my component, the very first thing to do is to parse an XML file thus my
script service provide a "parseBPXML()" method. The problem is where can i
store this file in order to make accessible by my component, I've already
Injected the Environment component but I can't understand where to put my
file (i.e. which is the "permanent directory") and how to access it.
Check your xwiki.properties file and search for permanentDirectory.
Thanks
