The output is;

Advisor Tag handler

HelloSangi!!!You are in do Tag

Your Advice is:::you are here in getAdvice
Body content of JSP goes here!!! Sangi

I am expecting error as the body content is empty(there shouldnt be anything inside the body of the tag).

I assume because of getJspBody().invoke(null) the body of the tag is getting printed. Can anyone of you please let me know my assumption is correct?
