9 -2. The "New WebObjects Component" dialog opens. The only required field is the WOComponent name. Let's just use the default "MyComponent" as the component name. I generally deselect "Create body tag" and "Create api file", but you can leave them if you'd like. Click "Finish" to continue.

Note that you must save each of the editors individually for changes to be visible ~-~- even in the split view. If your file is unsaved, you will see a "**" next to the filename in the tab at the top of the editor.**

Switch to the WOD editor and add a Greeting element that is of type "MyComponent" (you'll notice that code completion now shows MyComponent in the list, because it is a subclass of WOElement).

39 -7. Adding a new Java file technically is not a violation of Hot Code Replacement, however, WO seems to not like a new HTML template appearing in your bundle that it doesn't know about. So go ahead and stop your app if it's running and then re-debug it (from the previous instructions). You should now have a "Hello!" in Main.wo is generated by the embedded MyComponent component.
