I found the solution.... I am using the spring_module for jbpm3.1. with jbpm3.2.1 The problem is in the LocalJbpmConfigurationFactoryBean of the module. This class instanciate the jbpmConfiguration but the problem is that it uses only a new JbpmConfiguration(ObjectFactory) to instanciate my configuration. This methode doesn't put this instanciation on the jbpmConfiguration's ObjectFactory. The JobExecutor use this ObjectFactory to get the JbpmConfiguration ... Then if you don't modify this module sources it won't work .... I changed this : View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4103248#...
