Thanks again for your lot of
Srinivas,
I talked about the questions on design pattern in the post just above yours
Rajendra,
I don't have the free mock links except the mock on javaranch and jdiscuss.
Singh,
I read the HFSJ once 6 month ago then took a pause then I prepared it 4-5 weeks (2H/day + almost all the weekends) but I already have 4 years of experience on servlets/jsp (no custom tags, not much security, no filters...);
In my opinion, the most important thing to do is to identify your weak points (and not to read all the book many times), and in order to do it you must do the tests.
Thanks and good luck for you
Gab
