thanks to all
Bert,
ok, maybe i did not read deeply enough HFSJ (i am french so my apologies sometimes i dont understand everything ...) ,
but i think is HFSJ dont talk about dynamic attributes yes, then directives in tag files are not enough explained (for example the variable directive), then the variable attribute in the declaration of a tag in the TLD and the use of this (i got one question about using variable in a taglib) is not explained and there is not enough explanation about
JSP pages as XML documents. And the beanName attribute is not really enough explained.
last point is it does not cover enough the distributable web applications.
Anyway, your book is really really good and i have to thank you for the great help it brought to me. I really agree with all the people who consider HFSJ is the best book to prepare for this exam.
