When you create an application that uses, for example image or sound files, these resource files need to be included into the jar package during the build. In MTJ this is automatically done, but these resources have to be added into the project's res folder before the build command is executed. The project's res folder is created by the project wizard.
To add the resource files into a project
In the Package Explorer view, right-click the project's res folder. From the context-sensitive pop-up menu:
Select Paste if you have copied the resource
to your computer's clipboard.
OR
Select
Import if you want to use the import wizard.
Perform the import.
The resource is added to the res folder.
