"java.lang.NullPointerException"

Hi,
I'm writting you because I need some help with a problem.
I'm trying to integrate RapidMiner with BizAgi Studio using a Web Service, and when this one wants to run a Process I have a java.lang.NullPointerException.
I don't know why is this happening because when I run the process by itself in RapidMiner I don't have any problem (using the same files).
Here it's the XML log:
