Research And Implement Of Inter-Region Components' Transaction

As a support software reuse infrastructure, Component Library provides a description, classification, storage and retrieval functions for the software component. It has been researched as a hot spots and focus by domestic and foreign academic research for more than 10 years.As lots of information isolated islands, with the development of computer network and technology in software reuse, much 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, establish one common platform for sharing, It can help users publish, retrieve and buy the target components from various repositories in the platform 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. In order to make sure of the convenience of the transaction, it implemented the publicsh information module for region and integration platform.2. It researched and implemented Inter-Region Transaction system Based on JMS, and the JMS is used to process the order forms and the communication among regions while the components are being downloaded..3. It researched and implemented SSO (Single Sign-On), to make the user to access the Inter-Region Platform without repeatedly logging on, it can improve the service for component transaction.4. It researched the security of JMS and gave a model of JMS to resolve the problems how to ensure the security in the process of components transaction.
