Creating a Project in JDeveloper
JDeveloper projects organize the file elements that are used to create your program. In the Applications Navigator, projects are displayed as the second level in the hierarchy under the application.
Projects manage environment variables, such as the source and output paths used for compiling and running your program. Projects also maintain compiler, run-time, and debugging options so that you can customize the behavior of those tools for each project.
A project file has the file extension .jpr and keeps track of the source files, packages, classes, images, and other elements that may be needed for your program. You can add multiple projects to your application to easily access, modify, and reuse your source code. You can view the content of a project file by using any text editor.
There are two ways to create a project in JDeveloper. The first way is when you create an application. Depending on the application template that you select, one or more projects are created automatically. Sometimes you are presented with a wizard page enabling you to name the project and set its technologies.
