5 -Let's add a new WO Component to our project.

7 -~1. Right-Click/Ctrl-Click on the project and select "New" => "WOComponent"

13 -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.

19 -3. You should now have a new MyComponent.java in your source folder, a MyComponent.wo folder at the project root (or whereever you decide to add the component), a wod, woo, html, and optional api file, and the Component Editor should now open to show your new component.

25 -4. Switch to the "Java" tab and add the "greeting" method as defined in the picture below and save.

31 -5. Now switch to the "Component" tab, add a <webobject> tag in the HTML and save, then the WOD definition and save. 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.

37 -6. Now switch to your Main.wo Component Editor "Component" tab and add a <webobject> tag named "Greeting" and save. 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).

43 -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.
