System and method for dynamic generation and customization of web service client applications for terminals

1. A method for customizing an application template for an executable application in a mobile device, the method comprising:

receiving, in a computer processor, an application template assembled based on a plurality of interface element definitions, wherein the application template comprises at least one of a message template, a data template, a presentation template, and a workflow template, wherein the plurality of interface element definitions are generated from a parsed schema definition of a web service, wherein the plurality of interface element definitions include a message definition, a data definition, and a presentation definition; and a workflow element, wherein the workflow element specifies a behavior of the message definition, the data definition, and the presentation definition; and wherein the message template, the data template, the presentation template, and the workflow template are generated using the plurality of interface element definitions; and

adding, removing, or modifying, in a customization environment, relationships between the message definition, the data definition, and the presentation definition of the application template, wherein the customization environment includes at least one member selected from the group consisting of: a message designer, a data designer, and a screen designer.

2. The method according to claim 1 , wherein at least one of the message template, the data template, the presentation template, and the workflow template is expressed in a structured definition language.

3. The method according to claim 1 , further comprising including in the message template, a communication message definition of a communication message to be exchanged between the web service and the executable application.

4. The method according to claim 1 , further comprising including in the data template, a definition of a data structure to be used by the executable application.

5. The method according to claim 1 , further comprising including in the presentation template, a presentation and functionality presentation definition of a presentation and functionality of a presentation element for presentation on the mobile device.

6. The method according to claim 5 , further comprising including the presentation and functionality presentation definition mapped to one of message definitions in the presentation template.

7. The method according to claim 6 , further comprising linking a plurality of presentation templates to represent a workflow sequence of the web service.

8. A method for dynamically generating an executable application for accessing a web service, the method comprising:

obtaining, in a computer processor, a schema definition of the web service, wherein the web service responds to the executable application executed on a wireless device via a wireless network;

parsing the schema definition of the web service;

generating a plurality of interface element definitions for an application template from the parsed schema definition of the web service, wherein the plurality of interface element definitions include a message definition, a data definition, and a presentation definition; and a workflow element, and wherein the workflow element specifies a behavior of the message definition, the data definition, and the presentation definition;

assembling the application template based on the plurality of interface element definitions, wherein the application template comprises at least one of a message template, a data template, a presentation template, and a workflow template, and wherein the message template, the data template, the presentation template, and the workflow template are generated using the plurality of interface element definitions; and

generating the executable application using the assembled application template, wherein the assembled application template allows the executable application executed on the wireless device to access the web service.

9. The method according to claim 8 , wherein the workflow element is expressed in a script.

10. The method according to claim 8 , wherein the message template, the data template, the presentation template, and the workflow template are expressed in a structured definition language.

11. The method according to claim 8 , further comprising including in the message template, a communication message definition of a communication message to be exchanged between the web service and the executable application.

12. The method according to claim 8 , further comprising including in the data template, a definition of a data structure to be used by the executable application.
