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 -Vincent
Thank you, Giordano.

Isn't the problem that it should be
#if("$!request.evolver" == "1")
And not
#if("$!request.evolver" == 1)
I thought so too but I tested and it works. I checked the Velocity documentation [1] and the explanation is:
"In the last case (when objects are of different classes), the toString() method is called on each object and the resulting Strings are compared."
Thanks, Marius

Dear Vincent,
Tank you for your reply, I would try what you suggested in the
afternoon,
but regarding the "evolver=1 request param", I've set it equal to 1 together with POST command in order to make it always true ensuring that my component is started every time. My thoughts were wrong?
Giordano.
