Abstract

A deployment server can include a profile data store, a generic application data store, and an optimizer. The profile data store can contain a plurality of attributes for devices and associate different optimization parameters or optimization routines to each of the stored attributes. The generic application data store can contain at least one generic application written in a device independent fashion. The optimizer can receive application requests from an assortment of different requesting devices and can dynamically generate device-specific applications responsive to received requests. For each requesting device, the optimizer can determine attributes of a requesting device, utilize the profile data store to identify optimization parameters or optimization routines for the requesting device, and generate a device-specific application based upon data from the profile data store and based upon a generic application retrieved from the generic application data store.

Claims

performing a first plurality of application optimizations;

following performance of the first plurality of application optimizations, receiving by the deployment server a request from a client for an application;

dynamically analyzing capabilities of a device upon which the client is hosted;

identifying a generic version of the requested application from a generic application data store that stores at least one generic application written in a device-independent fashion;

determining whether a client-optimized application exists for the identified generic version of the requested application and the device upon which the client is hosted;

upon determining that a client-optimized application does not exist for the identified generic version of the requested application and the device upon which the client is hosted, performing the following steps;

matching the client with at least one device profile stored in a profile data store in the deployment server, the matching being based at least in part upon the capabilities of the device upon which the client is hosted;

determining attributes specific to the client based upon the matching device profile; and

dynamically generating at runtime a client-optimized application based upon the determined attributes and the identified generic version of the requested application by building a plurality of scripts based upon the determined attributes, processing the plurality of scripts within an optimizer engine configured to remove unneeded classes, methods, and fields from the identified generic version of the requested application, and iteratively executing the plurality of scripts to perform a second plurality of application optimizations;

identifying at least one software routine that is to be bundled with the client-optimized application so that the client is able to execute the client-optimized application, and creating a bundle including the identified at least one software routine and the client-optimized application, the bundle adhering to any formatting restriction specified by the client; and

conveying the client-optimized application to the client via the bundle.

2. The method of claim 1, wherein the identified generic version of the requested application is a JAVA programming language application, and wherein the client-optimized application includes pre-verified bytecode executables constructed at link time.

3. The method of claim 1, wherein the bundle adheres to the JAVA ARCHIVE (JAR) format.

4. The method of claim 1, wherein the on-demand application deployment environment is part of an integrated development environment, and wherein the integrated development environment creates, tests, and deploys e-business applications to mobile and wireless devices.

5. The method of claim 1, wherein any formatting restriction specified by the client is determined by directly interrogating the client.

6. The method of claim 1, wherein any formatting restriction specified by the client is parsed from the request.

7. The method of claim 1, wherein any formatting restriction specified by the client is determined from profile data stored in the profile data store.

8. A computer program product including machine-readable storage having a set of instructions intended to cause a system having an information processing capability to perform an operation for optimizing applications within a deployment server in an on-demand application deployment environment, the operation comprising:

performing a first plurality of application optimizations;

following performance of the first plurality of application optimizations, receiving by the deployment server a request from a client for an application;

dynamically analyzing capabilities of a device upon which the client is hosted;

identifying a generic version of the requested application from a generic application data store that stores at least one generic application written in a device-independent fashion;

determining whether a client-optimized application exists for the identified generic version of the requested application and the device upon which the client is hosted;

upon determining that a client-optimized application does not exist for the identified generic version of the requested application and the device upon which the client is hosted, performing the following steps;

matching the client with at least one device profile stored in a profile data store in the deployment server, the matching being based at least in part upon the capabilities of the device upon which the client is hosted;

determining attributes specific to the client based upon the matching device profile; and

dynamically generating at runtime a client-optimized application based upon the determined attributes and the identified generic version of the requested application by building a plurality of scripts based upon the determined attributes, processing the plurality of scripts within an optimizer engine configured to remove unneeded classes, methods, and fields from the identified generic version of the requested application, and iteratively executing the plurality of scripts to perform a second plurality of application optimizations;

identifying at least one software routine that is to be bundled with the client-optimized application so that the client is able to execute the client-optimized application, and creating a bundle including the identified at least one software routine and the client-optimized application, the bundle adhering to any formatting restriction specified by the client; and
