B4J Question [SOLVED] ABMaterial problem on running with MasForm

I have a little problem with Mashform (and funny also)

I created a jar with b4j using ABMaterial with some MashForms on it, In my notebook runs perfect, both in debug and release mode, buth when I copy everything to the server and runs on it everything works ok except the MashForms, they throw the following error:
