This paper presents an architecture for accessing distributed services with embedded systems using message oriented middleware. For the service discovery a recommendation system using case-based reasoning methods is utilized. The main idea is to take the context of each user into consideration in order to suggest appropriate services. We define our context and discuss how its attributes are compared. The presented prototype was implemented for Ricoh & Sun Devel- oper Challenge. Thus the client software was restricted to Ricoh's Multi Functional Product as an embedded system. The similarity functions were designed and tested using myCBR, and the service recommender application is based on the jCOLIBRI CBR framework.
