Hi to all,
I'm using the jbpm-starters-kit-3.1.3 and try to set and get variables from the
process instance, where all my variables are serializable objects that are instances of a
TaskRef class. No problem, but when i try to get the variable from the process instance, i
get the following error:

I solved this problem by putting the requested class visible to the jbpm in the lib
directory of the server. But after that a get another error:
