Hello hzhang_jn, thank for the answer. The class "ar.edu.unl.rectorado.ilitias.app.comitente.ControladorComitente" is in the war project.
There is a detail i omitted, the class which use reflection is in a library (.jar) included in the war project, when i debugged the code could see that only had access to the classes in that jar library. The question still is why in Galssfish 2.x the same code is working :(
I will try to deploy with the compatibility with version 2.
thanks again
