As with all Swing components, get the underlying
model.  In the case of a JList, the "concrete"
underlying model is DefaultListModel, so when you
ask

   myList.getModel();

you have to typecast the returned value to DefaultListModel
in order to use the methods which add an object to the
list.  Note that the list may not contain just String
object, but any object which has a "toString()" method.


It may be time to read the tutorials on Swing at the
java.sun.com Web site, or better yet, get a good book
on Swing.  It's complex, so there's no better way
to invest in your career than to buy a good book now
and then.

To add to what I just wrote, you should be using
the "drill down" feature of JBuilder to your
advantage.  Put the cursor anywhere in the word
"JList" in your source file, hit Control-return,
and you are looking at the source for JList.
 From there, use the Structure Pane to flip to
the "getModel()" method.  Note that it returns
an interface, ListModel.  Search the JList.java
file in your editor for "listmodel" and read the
discussions.  Or flip to the "Doc" tab, and read
them there in more nicely rendered HTML.  See
the links to the various tutorials and articles.
One in particular is well-suited to answering
your question.

Finally, drill down into DefaultListModel, and take
that lesson to the bank by using the drill down
technique to become more familiar with any API
which comes with source code.

Thanks.
I went through the whole help file, and some of the Java, and found the
answer, namely, adding the objects through the DefaultListModel and not
the JList directly.
