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

17:01:30,829 INFO [DeploymentPoller] Deployment of artifact TvShowsOrchestrations successful: [

And now, let's invoke again :

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 ...
