| Abstract: |
| A method is proposed in this paper for resolving dynamic service evolving based on OSGi. First, use indirect method for updating service definition based-on OSGi. The method can make dynamic evolving transparent. Then, divide service definition into implementation and data, which makes fields in service instance consistent and evolvable. The adding/deleting service during evolving is also discussed. A project is implemented, which can direct how to design, execute and evolve updatable service. The methods mentioned in the paper may be helpful to evolving components, service and object-oriented software. |
