Abstract: A method is provided for encapsulating and accessing components, comprising: configurating component warehouse and storing components acquired from the Internet into the component warehouse to form a component warehouse computer; configurating a component directory library on another computer to form a component directory library computer; fetching component from the component computer by a user computer, encapsulating the component to form a encapsulated component, and organizing and storing the encapsulated component in the component directory library computer; and performing unified access to component resources by a user computer based on the component encapsulation information in the component directory library computer. The method can implement unified description and efficient organization of the existing component resources, to thereby support efficient retrieval and unified access to the component resources by high level applications.
