Dear gurus,
I tried to follow example given in netbeans 6.0 kb about file upload component.
I have an error on line:
ServletContext theApplicationsServletContext = (ServletContext) this.getExternalContext().getContext();
it says cannot find symbol getContext();
I tried to remove the getContext() but it says inconvertible types.
Anybody can please help me?
