Troubleshooting in the IDE

If a Class that Uses JFC Will Not Run
If you created a class and wrote code for it that uses JFC, then you must update the class path for it to include the path to the JFC project directory.   Otherwise, the class will not run.

To update the class path:

  1. Select the class in a browser.
  2. From the class's pop-up menu, select Run, Check Class Path.   This will open the class Properties notebook to the Class Path page.
  3. Next to the Project Path field, click Compute Now.   The JFC project path will be added. 
  4. Enable the Save to Repository (as default) check-box.
  5. Click OK.
