Yes. This is my first project.
I went through the first step of of the project: Creating a GWT
application. When I created it, a message popped up in the Eclipse
console:
Encountered a problem: Unexpected exception
Please see the logs [/tmp/enhance40780.log] for further information.

Step 2, Testing the default project components, resulted in nothing
being displayed (although the Eclipse console flickered). Assuming
that something got logged about the problem somewhere, do you know
where that somewhere would be?
With regard to SWT, I believe that's exactly correct. There are 4
jnilibs in the toolkit with swt in their name and I presume they
implement at least part of the Software Widget Toolkit. They are
clearly carbon and not gtk which makes sense because I'm running on a
Mac, not Linux. But the error I get using the GWT Designer is no swt-
pi-gtk-3062 in java.library.path. Also, I don't believe the Designer
even looks at the GWT Eclipse plugin. The one must-be-set preference
in the Designer configuration is where in the file system to find the
toolkit.
