Abstract

A method, apparatus, and article of manufacture provide a component-based computing system having both publicly accessible and privately-only accessible computing components within multiple applications for providing component addressing/identification and naming spaces. A requested processing component is initiated by a calling component within a local computing system having one or more applications. The identity of the requested processing component, including an identity of a class ID and an identity of a partition from a request to activate a component initiated by a calling component, is obtained using configuration data for the requested component. The configuration data provides an indication of public-private status for the requested component. An instance of the requested component can be activated based on the public-private status.

Claims

1. A computer implemented method of activating a requested processing component initiated by a calling component within a local computing system having one or more applications, the method comprising:

activating an instance of an application associated with one or more processing components;

receiving a request from a calling component to activate one of the processing components associated with the application;

determining an identity of the requested processing component, including an identity of a class ID from the request to activate the requested component initiated by the calling component;

obtaining configuration data for the requested component, the configuration data comprising an indication of public-private status for the requested component;

if the configuration data indicates that the requested component is a public component, activating an instance of the requested component;

if the configuration data indicates that the requested component is a private component, performing the following;

determining if the requested component is a member of the application that also includes the calling component as a member; and

if the requested component and the calling component are members of the same application, activating an instance of the requested component.

2. The method according to claim 1, wherein the identity of the calling component corresponds to an identity obtained from a central directory service.

3. The method according to claim 2, wherein the central directory service communicates with the local computer over a communications network.

4. The method according to claim 1, wherein the calling component is located on a remote computing system.

5. The method according to claim 4, wherein the calling component transmits the request to activate a component to the local computing system across a communications network.

6. The method according to claim 5, wherein the communications network is the Internet.

7. A computer implemented method of activating a requested processing component initiated by a calling component within a local computing system having one or more applications, the method comprising:

determining an identity of the requested processing component, including an identity of a class ID and an identity of an application from a request to activate a component initiated by a calling component;

activating an instance of an application associated with one or more processing components;

receiving a request from a calling component to activate one of the processing components associated with the application;

obtaining configuration data for the requested component, the configuration data comprising an indication of public-private status for the requested component;

if the configuration data indicates that the requested component is a public component, activating an instance of the requested component;

if the configuration data indicates that the requested component is a private component, performing the following;

determining if the requested component is a member of the application that also includes the calling component as a member; and

if the requested component and the calling component are members of the same application, activating an instance of the requested component;

wherein the identity of the calling component corresponds to an identity obtained from a central directory service; and

the calling component is located on a remote computing system that transmits the request to activate a component to the local computing system across a communications network.

8. A computer program data product containing computer readable medium encoding instructions for a method for activating a requested processing component initiated by a calling component within a local computing system having one or more applications, the method comprising:

activating an instance of an application associated with one or more processing components;

receiving a request from a calling component to activate one of the processing components associated with the application;

determining an identity of the requested processing component, including an identity of a class ID and an identity of a partition from the request to activate the requested component initiated by the calling component;

obtaining configuration data for the requested component, the configuration data comprising an indication of public-private status for the requested component;

if the configuration data indicates that the requested component is a public component, activating an instance of the requested component;

if the configuration data indicates that the requested component is a private component, performing the following;

determining if the requested component is a member of the application that also includes the calling component as a member; and

if the requested component and the calling component are members of the same application, activating an instance of the requested component.

9. The computer data product according to claim 8, wherein the identity of the calling component corresponds to an identity obtained from a central directory service.

10. The computer data product according to claim 9, wherein the central directory service communicates with the local computer over a communications network.

11. The computer data product according to claim 8, wherein the calling component is located on a remote computing system.

12. The computer data product according to claim 11, wherein the calling component transmits the request to activate a component to the local computing system across a communications network.

13. The computer data product according to claim 12, wherein the communications network is the Internet.

14. The computer data product according to claim 8, wherein the computer data product comprises a computer-readable medium having stored thereon a set of computer instructions.

15. The computer data product according to claim 8, wherein the computer data product comprises a computer data signal embodied in a carrier wave readable by a computing system and encoding a set of computer instructions.

16. A computing system for activating a requested processing component initiated by a calling component within a local computing system having one or more applications, the computing system comprising:

an activated application associated with one or more processing components;

an activation control module for receiving a request to activate one of the processing components associated with the application, the request being initiated by a calling component and activating an instance of the requested component;

an application identity module for determining an identity of one or more applications used to identify the requested processing component; and

a permit object activation module for determining whether an instance of the requested component can be activated, the permit object activation module using configuration data including a value of a public/private property to determine whether the request component can be activated, wherein the permit object activation module is programmed to;

if the configuration data indicates that the requested component is a public component, the permit object activation module allows activation of an instance of the requested component;

if the configuration data indicates that the requested component is a private component;

the permit object activation module determines if the requested component is a member of the application that also includes the calling component as a member; and

if the requested component and the calling component are members of the same application, the permit object activation module allows activation of an instance of the requested component.

17. The computing system according to claim 16, wherein the application identity module obtains the identity of the calling component from a central directory service.
