Hi;

I created normally class. And I want to get a ViewPart that in my
application this like

public class DisplayCycle {

public DisplayCycle(){

}

public void toDo(){

ReadDataView readDataView =
(ReadDataView)PlatformUI.getWorkbench().getActiveWorkbenchWi ndow().getActivePage().findView(ConstID.READ_VIEW_ID);

}

}

But I cant get it. The application throws a NullPointer exeception

What is the problem?

Hi Cenk,

You might separate the statement between each of the ".", and
assign to separate variables. Then you can determine which function
is returning null.

you can also try to brows throw stack trace to find out where the
problem has occurred. the reason of NPE should be in javadoc of method
which raised it ;)

hope this helps
