Une des objet de ta ligne 42 est null.
Si les ligne que tu connes respecte la mise en page de ta classe c'est celle-ci

Code :

engine = factory.createReportEngine(config);

donc factory ou config est null.
surement factory mais des trace pour vérifier et si c'est bien ça regarde pourquoi ta factory peut-être null
