Abstract

An application view control can allow users of a software tool to interact with Enterprise applications using simple Java APIs. This can allow a user who is not an expert in the use of a given Enterprise system to utilize its capabilities in a manner a Java programmer can understand. A developer can invoke application view services both synchronously and asynchronously, and can subscribe to application view events. The developer can use simple Java objects in both the service and event cases. The developer need not understand XML, or the particular protocol or client API for the Enterprise application, such as an Enterprise Information System (EIS).

Claims

1. A method for providing access to an application view service, comprising:

providing an application control wizard to create an instance of an application view control, including

generating a servlet to implement an interface to generate a control file, wherein the servlet accepts information from a user and returns configuration text used to generate the control file;

generating the control file from the configuration text representing the application view definition;

selecting services defined for the application view;

determining, by the user, at least one of a synchronous and an asynchronous invocation support for each of the selected services, wherein the synchronous invocation implements a request/response protocol when invoking said each of said selected service, and wherein the asynchronous invocation invokes said each of said selected service while generating the application view service;

generating classes to describe events for the selected services; and

generating the application view control adapted to interact with the application view service using the classes and the control file.

2. A method according to claim 1, wherein:

4. A method according to claim 1, further comprising:

generating a schema definition allowing the application view to be imported into an external software environment.

generating a Java type that contains fields for all element definitions at a root level of the schema.

6. A method according to claim 4, further comprising:

generated a Java type that is an inner class of a container class representing at least one of a request and response for the selected services.
