The development of distributed, reactive and collaborative services is quite challenging. Rapidly composing services for collaborative learning activities require some development methods and tools. This thesis presents an extension of the City Guide application, a platform that supports situated collaborative services developed by Surya Bahudar Kathayat his PhD thesis: On the Development of Situated Collaborative Services. The application was developed using the engineering method SPACE and its development tool Arctis. In the extension made, two new services instant messaging and group chat have be composed and integrated into the application. The two services have been identified as basic support services that are required for a true collaborative learning experience. Using the architecture of the application, the instant messaging and group chat services were developed as components that could be incorporated with other components within the application. The results show the instant messaging and group chat service as standalone functionalities that handle their own message routing within the application and hence did not require the use of any other messaging protocols. The results also show that by using this architecture with the necessary Arctis modifications, the City Guide application opens up for unexplored possibilities where new services can be rapidly developed and integrated.
