[Trong Van Ho <xmllist@yahoo.com>]

I think maybe this is the stupid quesion

i got a parser using SAX : myclass extends DefaultHandler

i got in trouble with "extends" .

I make a servlet import this myclass and using method of myclass but i always got an error "sealing violation"

    i attach my servlet and my trong.java for anyone can solve this problem

Thanks in advance
