Right now it seems like I am paddling backwards! Or, more like, I'm in California and I'm trying to get to Texas by traveling west. I'll get there, but it's gonna take a while. Thanks to all,

Subject: Re: InOverMyHead {"obviously"};
By the way, that snippet is from the "wod" file. The wod file is the "glue" that magically connects your html template to the corresponding java class.
MyPage.html <--> MyPage.wod <--> MyPage.java.
Looking at the little snippet below, here is an explanation of the pieces. Think about this over the weekend and get the conceptsinto the brain ;-)
EditButton ------------- That's the name you have chosen for the declaration and it maps to this fragment in your html template <webobject name = "EditButton"></webobject>
WOSubmitButton --------------------- That's the name of the "Dynamic Element" that contains the logic for rendering the element as HTML and firing your action when clicked on. This part of the wod conventionally corresponds to a WODynamicElement subclass, in this case one named WOSubmitButton.java, OR it can correspond to a custom reusable WOComponent (MyReusableComponent.wo for example) This is part of the WebObjects library, and you don't have the source code, hence why you got your original error below. If this corresponded to a WODynamicElement or WOComponent subclass in your source or Project Wonder's source, then clicking on it would show you the java source.
action ------- This is an api "binding" provided by the WODynamicElement (or reusable WOComponent) subclass. A binding allows passing of an argument both ways, depending on the context. In this case, the binding conceptually "pulls" your action method an invokes it.
editAction ------------ The name of your method. Must return WOActionResults instance (which can be a WoComponent page since WOComponent implements that interface public WOActionResults editAction() { <your logic here> }

EditButton: WOSubmitButton {
action = editAction;

"The source attachment does not contain the source for the file WOSubmitButton.class.
You can change the source attachment by clicking... "
So I click on the thing and it shows this path: /Developer/WebObjects/Versions/WebObjects543/System/Library/Frameworks/JavaWebObjects.framework/Resources/Java/javawebobjects.jar
Where exactly should I find WOSubmitButton.class?
Here is the contents of my wolips.properties file. I'm assuming there is a path issue?

You can type in a public instance variable, or command+click (or maybe it's control+click?) on the variable name in your .wod (or .html) file to generate the variable.

I took a java programming class years ago. I did not continue with it. Since then, my only programming experience has been with Realbasic, and that too was years ago. Now, I've decided to jump into webobjects. I have eclipse and WO 543 on intel mac. I can run a simple "hello world" program.
I find myself stuck. The instructions say: "So, to add a variable to keep track of our visitors name, click on the 'Interface' menu bar item and select 'Add Key...'."
