I am trying to execute a program with empty body content.


AdviceTag handler class has the code;

TLD has;

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?

It is sorta covered in the JavaRanch Style Guide.
