Accessing Resources in Runnable JARs
When exporting a project as a runnable JAR from Eclipse, external files such as images may be missing from the packaged JAR, despite being present within the original project.
To resolve this issue, the correct process should be followed:
- Create a Source Folder: Right-click the project in the Project Explorer Tree, navigate to "New" > "Source Folder," and create a new folder with an appropriate name (e.g., "resources").
- Add Files to Source Folder: Manually add the desired files, such as images, to the newly created source folder through the file system.
- Refresh Project: Return to Eclipse and refresh the project by right-clicking it in the Project Explorer. The added files should now be visible.
- Access Resources: To access the files in code, use the following format:
getClass().getResource("/path/to/file");
where "/path/to/file" is the relative path to the file within the source folder.
By following these steps, the files will be automatically included in the runnable JAR when it is created, ensuring their availability during program execution.
