  1. Launch the Common Project Wizard by clicking File ->New... menu option. The New Project wizard will be launched.
  2. Go through the instruction provided on top of the General tab.
  3. Keep the default project name and location for the purpose of this exercise. We don't have to provide "Notification" settings or "Remote Application/AppServer" settings for this exercise. Click on the Next button.
  4. In the Source tab provide the source files and folders of your local application. Click the Next button.
  5. Either use the default JDK which is bundled with AppPerfect DevTest4J or provide the proper JDK which you want to use with your application and click on the Next button.
  6. In the "Environment" tab provide the classpath for the sources added in the project.
  7. Click on "Verify Classpath" button to validate the classpath.

  9. In the "Target" tab select project type as "LOCAL".
  10. Provide the working folder. Working folder is that folder from where you want to run your application, this is specially useful when you are using relative paths in your application to fetch various things like images etc.

  12. Select the "Launch target application automatically" checkbox. Click on the Finish button.
