Sandro Martini commented on PIVOT-917:
--------------------------------------
Hi, I just committed an updated sample that works, but sorry for Groovy
Scripting (in the usual pivot-stuff-common-groovy project). The trick was to
define all methods required by Pivot in a class (for simplicity defined inside
the script) implementing Application (and with the right signature, not too
dynamically oriented, I know).
Then add a step to call the Groovy Compiler (and add the output class folder in
the classpath).
So probably for Pivot 2.1 we have only something to improve (already in
development, mainly related to classloaders), and not things to fix (I hope)
:-) .
Could you try to do the same in your samples (Jython) and tell something to us
(maybe add here in attach an updated version) ? Thank you very much.
