JDeveloper is used to create projects in Oracle SOA. The user opens JDeveloper and selects "New Application" which prompts them to name the application. This creates an application folder to store project configurations. In the next screen, the user names the project and selects "SOA" as the project type using the greater than and less than symbols. Finally, the user finishes by selecting "Empty Composite" to create an empty SOA composite project.
