Hi all,
I'm trying to externalize my SWT application into an executable jar file=

All classpaths seem to be correct but when I execute the jar with java =
-jar app.jar I get the following error:
Exception in thread "main" java.lang.ClassCastException
at org.eclipse.swt.layout.FillLayout.computeChildSize
at org.eclipse.swt.widgets.Composite.computeSize
....
and so on.
I downloaded the standalone SWT jar with the same version I developed my=
=
program with.
Does anyone know what I'm doing wrong?
Thanks in advance!

Your layoutData is probably incorrect.
Why don't you include a snippet of your code?

Hi,
I had the same problem when updating to SWT 3.2. In my case I forgot to
remove a GridData association when changing the layout from GridLayout
to FillLayout. 3.2 seems not to like this. Maybe you did the same mistake.
Hope that helped,
