Aim at the possible execution failure of composite component service because of source dis.

Based on the idea of autonomic computing,XManager takes RuleML as the definition mode for rule expression to form a rule base and includes a service component architecture(SCA) model to support data analyzing and business execution.

On the basis of analyzing SOA and its relative technologies,introduced three methods of adopting SOA to integrate service: using web service and enterprise service bus(ESB),using service component architecture(SCA),using business process executive language(BPEL) along with SCA and service data object(SDO),implementing the application integration from the service layer and the data layer.

Research on Architecture of Application Integration Based on SCA Model;

This dissertation starts from two norms——Service Component Architecture (SCA) and Java Business Integration(JBI),on the basis of summarizing traditional application integration technology and application integration of Web Services-based,the integration of Service-oriented architecture integration(SOI) is expounded.

As a programming model for building the service-oriented applications and systems, Service Component Architecture (SCA) simplifies the processes of development, assembly, and deployment for business components, and enhances the system\'s portability, reusability, and flexibility.

As for the problem of state loss in the process of evolution,this paper separates the data from the service component to resolve this problem under the support of the service-oriented component model in OSGi Release 4.

Along with the development of Service Computing,it become the hotspot to construct the application with the service component distributed on the grid environment.
