Where is org.eclipse.core.runtime.IStatus [message #156246]

The Eclipse platform API says that the class IStatus is part of the
org.eclipse.core.runtime package. However, I can't find it there and
neither, apparently, can Eclipse. The exact jar file that I have on my
system is:
C:\Program
Files\eclipse\plugins\org.eclipse.core.runtime_3.2.0.v200512 08.jar

I tried running a simple demonstration program that adds a selection
listener to a button as follows:

b.addSelectionListener(new SelectionAdapter(){
public void widgetSelected(SelectionEvent e) {
MessageDialog.openInformation
(shell,"SWT","Button selected.");
}
});

I ran this as an SWT Application from within Eclipse. The window with
the button show up just fine. But, when I click on the button, I get
the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/eclipse/core/runtime/IStatus
at ShellTest$1.widgetSelected(ShellTest.java:22)
at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListe ner.java:90)

I hope somebody can tell me what I am missing.

Thanks.

When your app executes it is outside eclipse, so you must ensure that
all required plugins are deployed with it. Just a suggestion - try
putting an import of IStatus into your app to see what missing plugin is
required at runtime. It should show up in the dependencies tab.
