Abstract

Under the present invention a native application intended for a client device is packaged within an OSGi bundle along with corresponding dependency information that identifies any prerequisites the native application might have. The client device will then be polled to determine if it has the necessary prerequisites. If not, the prerequisites will be obtained and packaged within their own OSGi bundles (i.e., if they have not been previously packaged). Thereafter, the various OSGi bundles containing the native application and any needed prerequisites will be loaded on the client device.

Claims

1. A computer-implemented method for resolving prerequisites for native applications in an Open Service Gateway Initiative (OSGi) framework, comprising:

packaging a native application for a client device and corresponding dependency information within a first OSGi bundle on a server, wherein the corresponding dependency information specifies at least one prerequisite on which the native application depends for proper operation on the client device;

polling the client device to determine if the client device has the at least one other prerequisite;

obtaining the at least one prerequisite if the client device does not have the at least one prerequisite; and

loading the at least one prerequisite and the native application on the client device.

2. The method of claim 1, further comprising registering the packaged native application and first OSGi bundle after the packaging step, wherein the registering step comprises storing the corresponding dependency information.

3. The method of claim 1, wherein the polling step comprises:

identifying the at least one prerequisite to the client device; and

receiving a response from the client device, wherein the response indicates whether the client device has the at least one prerequisite.

4. The method of claim 1, further comprising:

determining the at least one prerequisite, prior to the packaging step; and

generating the corresponding dependency information based on the at least one prerequisite.

5. The method of claim 1, wherein the at least one prerequisite comprises another native application.

6. The method of claim 1, wherein the at least one prerequisite is packaged with corresponding dependency information within a second OSGi bundle, and wherein the obtaining step comprises obtaining the second OSGi bundle.

7. The method of claim 6, wherein loading step comprises:

installing the first OSGi bundle and the second OSGi bundle within an OSGi environment of the client device;

deploying the first OSGi bundle and the second OSGi bundle within a native environment of the client device; and

removing the native application from within the first OSGi bundle and the at least one prerequisite from within the second OSGi bundle.

8. The method of claim 1, wherein the method is performed recursively.

9. The method of claim 1, wherein the dependency information is expressed as a package import statement.

10. The method of claim 1, wherein a name and version of the native application is represented in a name and version of the OSGi bundle.

11. A computer-implemented method for resolving prerequisites for native applications in an Open Service Gateway Initiative (OSGi) framework, comprising:

packaging a native application for a client device and corresponding dependency information within a first OSGi bundle on a server, wherein the dependency information specifies at least one prerequisite on which the native application depends for proper operation on the client device;

polling the client device to determine if the client device has the at least one other prerequisite;

obtaining the at least one prerequisite if the client device does not have the at least one prerequisite, wherein the at least one prerequisite is packaged within a second OSGi bundle that is accessible to the server; and

installing the first OSGi bundle and the second OSGi bundle within an OSGi environment of the client device.

12. The method of claim 11, wherein the first OSGi bundle and the second OSGi bundle are registered on the server after being packaged with the first native application and the at least one prerequisite.

13. The method of claim 11, wherein the polling step comprises:

identifying the at least one prerequisite to the client device; and

receiving a response from the client device, wherein the response indicates whether the client device has the at least one prerequisite.

14. The method of claim 11, further comprising:

determining the at least one prerequisite, prior to the packaging step; and

generating the dependency information based on the at least one prerequisite.

15. The method of claim 11, wherein the at least one prerequisite comprises another native application.

16. The method of claim 11, further comprising:

deploying the first OSGi bundle and the second OSGi bundle within a native environment of the client device; and

removing the native application from within the first OSGi bundle and the at least one prerequisite from within the second OSGi bundle.

17. The method of claim 11, wherein the at least one prerequisite is packaged with corresponding dependency information within the second OSGi bundle.

18. The method of claim 11, wherein the method is performed recursively.

19. A computerized system for resolving prerequisites for native applications in an Open Service Gateway Initiative (OSGi) framework, comprising:

a packaging system for packaging a native application for a client device and corresponding dependency information within a first OSGi bundle on a server, wherein the dependency information specifies at least one prerequisite on which the native application depends for proper operation on the client device;

a communication system for polling the client device to determine if the client device has the at least one other prerequisite;
