Please let me know if this is the incorrect newsgroup.

I receive a null pointer exception when I try to set a message on an
ManagedForm (running as a simple java application, i.e. no osgi):

Does org.eclipse.ui.forms support running in a simple SWT/JFace app? My
guess is no, since it depends on org.eclipse.ui (and through that
probably the Workbench as well) but I might be wrong.

It might be that you need to include a number of the equinox/osgi jar
files so that it can find the correct classes, even if you are not
running an OSGi/Eclipse application
