Dear Nigam ,
I think the answers are :
1.Identify methods that return an outer tag handler from within an inner tag handler
--TagSupport.findAncestorWithClass(Tag,class)
-- getParent()
2.the return value of PageContext.getOut()--JspWriter
what are the methods in the custome tag handler that accesses..
1. a given JSP page's implicit variable-- setPageContext(PageContext pc)
I couldn't understand what do u mean by Jsp page attribute .If that is about other implicit variables then u can use the methods of class PageContext and access them from Tag Handler class.U already have pageContext implicit variable
from setPageContext method.
But if u mean Custom Tag's attributes then we have other classes like TagExtraInfo and 2-3 others which can help u know more about Tag attributes.
