Steps
Do the following to unload a class: 
1.	Open an Application Manager, Applications Browser, Application Browser, or a TrailBlazer on Loaded Applications. 
2.	Select the class that you want to unload and its containing application. You can unload more than one class at a time. To select more than one class, press the Ctrl key while you select the classes. 
3.	From the Classes menu, select Unload. A window is displayed, asking you to confirm that you want the selected classes unloaded. 
4.	Select Yes to confirm; otherwise, select No. If you confirm, the classes are unloaded from your image. 
You can also use a Classes Browser or Hierarchy Browser to unload classes. To do so, you follow steps similar to the preceding steps. However, for step 3 select Unload Class from the Applications menu.
