A method, system and apparatus for interleaving XForms with JSF request processing can be provided. The system can include an XForms definition generated for a form configured for rendering in a Web application. Specifically, the XForms definition can specify a data model for data to be processed within the form. The system further can include a JSF code generation module programmed to process the forms model to produce a form bean, a faces configuration, and a JSF page for each navigable view defined in the XForms definition.

No: 15/853935 Application Filed: December 25, 2017 Assignees: International Business Machines Corporation (Armonk, NY, US) Claim: 1. A data processing system for interleaving XForms with Java server faces (JSF) request processing, the system comprising: a computer with memory and at least one processor; an XForms definition stored in the memory and generated for a form configured for rendering in a Web application, said XForms definition specifying a data model for data to be processed within said form; a JSF code generation module registered as a validator for any control in said form which has been bound to data for said form, the module being programmed to process said forms model to produce a form bean, a faces configuration, and a JSF page for each navigable view defined in said XForms definition, the form bean comprising getter and setter methods for every binding element, arbitrary data, control properties, event handler and submission in the form, the module executing in the memory of the computer; and, a lifecycle phase listener for forms processor integration, the listener dispatching every event which generates JSF request processing to a forms processing engine through the form bean in response to detecting the event. Claim: 2. The data processing system of claim 1 , wherein said XForms definition further comprises a plurality of bindings for data used by controls within said form with fields of said data model. Claim: 3. The data processing system of claim 1 , wherein said XForms definition further comprises statements linking actions in said form with corresponding command invocations. Claim: 4. The data processing system of claim 1 , wherein said form bean comprises getter and setter methods for a plurality of bound elements disposed in said form. Claim: 5. The data processing system of claim 1 , wherein said faces configuration specifies said form bean. Claim: 6. The data processing system of claim 1 , wherein said faces configuration comprises a lifecycle phase listener for forms processor integration. Claim: 7. The data processing system of claim 1 , wherein said faces configuration comprises navigational rules based upon navigation groups in said XForms definition. Claim: 8. The data processing system of claim 7 , wherein each JSF page comprises a server page generated for each of said navigation groups. Claim: 9. A method for interleaving XForms with Java server faces (JSF) request processing, the method comprising: rendering a JSF request to generate a forms context for a form; registering a forms processor as a validator for at least one control in said form which has been bound to data for said form; accepting data for said form and applying control data for said accepted data; calling said validator to perform validations on said control data for said accepted data; applying said accepted data to a model instance inside said form; and, dispatching every event which generates JSF request processing to said forms processor through a form bean in response to detecting the event which generates request processing, the form bean comprising getter and setter methods for every binding element, arbitrary data, control properties, event handler and submission in the form. Claim: 10. The method of claim 9 , re-querying instance data and control properties through said form bean. Claim: 11. A computer program product comprising a non-transitory computer usable medium including computer usable program code for interleaving XForms with Java server faces (JSF) request processing, said computer program product including; computer usable program code for rendering a JSF request to generate a forms context for a form; computer usable program code for registering a forms processor as a validator for at least one control in said form which has been bound to data for said form; computer usable program code for accepting data for said form and applying control data for said accepted data; computer usable program code for calling said validator to perform validations on said control data for said accepted data; computer usable program code for applying said accepted data to a model instance inside said form; and, computer usable program code for dispatching every event which generates JSF request processing to said forms processor through a form bean in response to detecting the event which generates request processing, the form bean comprising getter and setter methods for every binding element, arbitrary data, control properties, event handler and submission in the form. Claim: 12. The computer program product of claim 11 , further comprising computer usable program code for re-querying instance data and control properties through said form bean.
