Hi.
Here is a weird problem I'm encountering :
[EMAIL PROTECTED]:~/TvShowsOrchestration$ tomcat.sh stop
... bla bla bla ...

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)

Ouch ... it seems that my XSL stylesheet does not work ... BUT ...
let's redeploy the process :
[EMAIL PROTECTED]:~/TvShowsOrchestration$ ant deploy
Buildfile: build.xml
compile:

And now, let's invoke again :

So : MY STYLESHEET works ! Let's restart tomcat :
[EMAIL PROTECTED]:~/TvShowsOrchestration$ tomcat.sh restart
[EMAIL PROTECTED]:~/TvShowsOrchestration$ invoke.sh
http://localhost:8080/ode/processes/TvShowsOrchestrations/process
And ... null pointer exception again ...
Any ideas ? Processes are deployed with 'in-memory' set to 'true', but
it does not change anything to change it to 'false'.
