Hi Stefania,
Let me try to give you an answer:
-when I make the attribute I need to choose Object on netbeans :is it correct?
You can make it work, but
you should use the type you are using (i.e. java.util.List)
-the attribute is movieList but can I set another attribute - movie - on JspContext, regardless to TLD?
No, you can't.
This won't work:
Attribute name invalid for tag Simple5 according to TLD
You are not setting an attribute but filling the body of the tag.
Regards,
Frits
