The recent version of UML 2.0 (in year 2006) specifies activities and actions, which allow describing low level behavior of software system being modeled, in implementation independent fashion. This work analyzes suitability of UML 2.0 activities and actions for generating full program code (or as many as possible). It also proposes a method for generating program code from UML 2.0 activities and actions, which consists of a way to express UML activities with concurrently executing actions in a sequential execution scenario and a way to determine the exact code template (among the few possible) for UML activity elements based on identifying the particular context of element in question.
