Bug 37249 Export Javadoc does not give any error when the path to javadoc.exe is bogus
Version: 2.1.0 Build id: 200303272130 I had a bogus path to javadoc.exe in Preferences/Java/Javadoc. When I clicked Finish in the Export/Javadoc wizard, nothing happened. I gave up using the feature until today when I ran accross my bad Preference setting. Obviously, the wizard needed to give the user some kind of error message. (FYI, this happened when I upgraded my set up from Sun's 1.4.1_01 to 1.4.1_02.)
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/JavadocPreferencePage.java
cmd= store.getString(PREF_JAVADOC_COMMAND);

		return cmd;

	public JavadocPreferencePage() {
		setPreferenceStore(JavaPlugin.getDefault().getPreferenceStore());
		
	}
	
	/*

	public void createControl(Composite parent) {
		super.createControl(parent);
		WorkbenchHelp.setHelp(getControl(), IJavaHelpContextIds.JAVADOC_PREFERENCE_PAGE);
	}	
	
	/*

		initializeDialogUnits(parent);
