Abstract

A system and method for integrating business logic implemented in Enterprise JavaBeans (EJBs) into a user interface framework are disclosed. A design-time environment includes an analyzer that analyzes selected EJBs and generates a model representation of the selected EJBs, and further includes a metadata provider to provide additional metadata to the model representation. A runtime environment has a generic model component to access the selected EJBs based on their model representation, and executes the selected EJBs in the user interface framework.

Claims

1. A method for using Enterprise JavaBeans (EJBs) in a user interface component of an application, the method comprising:

generating a model representation of one or more EJBs;

storing the model representation of each of the one or more EJBs with additional metadata; and

during runtime of the application, accessing the one or more EJBs in the user interface via a generic model component that accesses the model representation of each of the one or more EJBs.

2. A method in accordance with claim 1, wherein the model representation of the one or more EJBs is generated in a design-time environment for the application.

3. A method in accordance with claim 1, wherein the additional metadata includes a maximum field length, label texts, and information about cardinality on associations to enable validation checks.

4. A method in accordance with claim 1, further comprising providing the one or more EJBs for being browsed by a developer.

5. A method in accordance with claim 1, further comprising declaratively binding the model representation of each of the one or more EJBs to the user interface.

6. A method in accordance with claim 1, further comprising generating typed model class files based on generic model components for each of the one or more EJBs.

7. A method in accordance with claim 6, wherein the typed model class files uses the generic model component to access the one or more EJBs.

8. A method for using Enterprise JavaBeans (EJBs) in a user interface component of an application, the method comprising:

providing one or more EJBs to a developer;

receiving, from the developer, an indication of selected EJBs from the one or more EJBs to be used in the user interface;

generating a model representation of the selected EJBs; and

storing the model representation of each of the one or more EJBs with additional metadata.

10. A method in accordance with claim 8, further comprising accessing the selected EJBs in the user interface during runtime by accessing the model representation of each of the selected EJBs.

11. A method in accordance with claim 8, wherein the additional metadata includes a maximum field length, label texts, and information about cardinality on associations to enable validation checks.

12. A method in accordance with claim 11, further comprising generating typed model class files based on the model representation of each of the selected EJBs.

13. A method in accordance with claim 12, wherein accessing the selected EJBs is done via a generic model component that accesses the model representation of each of the selected EJBs.

14. A method in accordance with claim 13, wherein the typed model class files uses the generic model component to access the one or more EJBs.

15. A system for integrating business logic implemented in Enterprise JavaBeans (EJBs) into a user interface framework, the system comprising:

a design-time environment having an analyzer that analyzes selected EJBs and generates a model representation of the selected EJBs, and a metadata provider to provide additional metadata to the model representation; and

a runtime environment having a generic model component to access the selected EJBs based on their model representation, and executes the selected EJBs in the user interface framework.

16. A system in accordance with claim 15, wherein the design-time environment further includes a code generator that generates typed model class files on top of the generic model components of the runtime environment.
