Abstract

Embodiments of the invention provide an IDE tool that provides rapid application development features for a variety of disparate data sources. Further, developers may customize and extend the rapid application development features to suit their development needs in a particular case. In a particular embodiment, the rapid application development template may be configured to generate a set of configuration files localized used to deploy a “lightweight” application, such as a web-service, to a particular application server.

10. A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program, when executed on a computer, causes the computer to perform an operation for generating application source code or development project artifacts for a software development project, the operation comprising:

receiving a selection of an input resource;

parsing the input resource to identify a resource type of the input resource;

generating a collection of template-input data from the input resource, based on the resource type and content of the input resource;

identifying a template corresponding to the resource type, wherein the template specifies an output resource type that may be generated from the template;

generating content of the output resource, based on the template and the template-input data; and

storing the content of the output resource within a project file associated with the development project.

11. The computer program product of claim 10, wherein the input resource is a database model, and wherein generating content of the output resource comprises:

generating at least one database statement to access a database represented by the database model;

encapsulating the statement within application source code;

storing, as the content of the output resource, the application source code.

12. The computer program product of claim 10, wherein the input resource is application source code referencing that includes at least one database statement, and wherein generating content of the output resource comprises:

generating at least one of database creation statement or a database schema corresponding to the database statement; and

storing, as the output resource, the at least one database creation statement or the database schema.

13. The computer program product of claim 10, wherein the input resource is a database query, and wherein generating content of the output resource comprises:

generating application source code configured to invoke the database query;

generating application source code configured to store a result from invoking the database query; and

storing, as the content of the output resource, the application source code.

14. The computer program product of claim 10, wherein the input resource is selected from at least one of a Java®

source code file, an XML JPA object, an SQL database query, a Java model, a database schema, and a JSON file.

15. The computer-readable storage medium of claim 10, wherein the output resource is selected from at least one of a Java®

source code file, an XML JPA object, an SQL database query, a Java model, a database schema, and a JSON file.

16. The computer program product of claim 10, wherein the template is customizable by the user of the IDE tool.
