Research And Implement Of Components' Retrieval And Inter-Region Transaction

Lots of Component Repositories that established by various regions need to share their components' information nowadays. It needs to integrate the isolated and heterogeneous repositories through some collaboration mechanism to achieve better sharing of component information.. It can help users find the target components from various repositories through the public network easily.From the view of application, this research modified the System of the Jade Bird Component Repository and added the new functions for it to meet the new changed requirements. The study includes the following items:1. Analyzed the architecture of the Jade Bird Component Library's System and the Data Model of the Component Information Repository, and studied the principle of its component retrieval, improved the algorithm of the component retrieval to achieve better efficiency and to adapt the concurrent retrieval.2. Added the validation and filter function of the components for the components retrieval of the Region Component Repository Platform.3. Simplified the selection processes of the classifications by Ajax technology.4. Studied and implemented the SSO (Single Sign-On) to make the user to access the Inter-Region Platform.5. Studied and implemented the components transaction of the Region Component Repository Platform.6. Proposed a mechanism of transaction that based-on the JMS middleware and implements it in the environment of the Weblogic Server 7.0.7. Implemented the privilege management function of components download.8. Implemented the components download between Regions through SSO (Single Sign-On).
