i have a base action class in which i declare a variable of type
ServletContext:
public abstract class BaseAction extends Action
{
protected ServletContext ctx = servlet.getServletContext();
...
}
yet i always get a NullPointerException on this line when struts tries to
instantiate a subclass of this base class. why?
