As far as we are, there is no trouble. Nos, let's try to invoke the process (each process
using xsl stylesheet has the same weird behaviour) (invoke.sh is basically a 'curl | xmllint
--format -' script)

mosser@asmodeus:~/TvShowsOrchestration$ invoke.sh http://localhost:8080/ode/processes/TvShowsOrchestrations/process

Ouch ... it seems that my XSL stylesheet does not work ... BUT ...
let's redeploy the process :

mosser@asmodeus:~/TvShowsOrchestration$ ant deploy
Buildfile: build.xml
compile:

deploy:
     [copy] Copying 1 file to /opt/tomcat/webapps/ode/WEB-INF/processes/TvShowsOrchestrations
     [copy] Copying /Users/mosser/workspaces/seduite/TvShowsOrchestration/OnTvTonight.cbp
to /opt/tomcat/webapps/ode/WEB-INF/processes/TvShowsOrchestrations/OnTvTonight.cbp

reload:
   [delete] Deleting /opt/tomcat/webapps/ode/WEB-INF/processes/TvShowsOrchestrations.deployed

BUILD SUCCESSFUL
Total time: 2 seconds

Tomcat logs :
17:01:30,054 INFO  [BpelServerImpl] Unregistered process {http://rainbow.i3s.unice.fr/mosser/jSeduite/orchestrations/tv}OnTvTonight-10.

[{http://rainbow.i3s.unice.fr/mosser/jSeduite/orchestrations/tv}OnTvTonight-11]

And now, let's invoke again :
mosser@asmodeus:~/TvShowsOrchestration$ invoke.sh http://localhost:8080/ode/processes/TvShowsOrchestrations/process
 % Total    % Received % Xferd  Average Speed   Time    Time     Time Current

      <tns:showTitle/>
    </tns:show>
    <!-- others french tv shows goes here ... -->
  </tns:shows>
</axis2ns7:OnTvTonightResponse>

So : MY STYLESHEET works ! Let's restart tomcat :
mosser@asmodeus:~/TvShowsOrchestration$ tomcat.sh restart
mosser@asmodeus:~/TvShowsOrchestration$ invoke.sh http://localhost:8080/ode/processes/TvShowsOrchestrations/process

And ... null pointer exception again ...
