I was preparing since last 4 months but the process was not in full pace , I used to read the HFJS daily for 1-2 hrs . But since last 1 month I devoted 3-4 per day to HFJS , I completed it 2 times , but there were some topics in which I was not feeling full confident topics like
1. Listeners (got confused where to make entry of SessionActiovationListener in DD or not ), alse distributed environment handling was also not clear .
2. Custom tags - there is lot to remember , got confused in getParent method , simple tag can have simple and classic parent , but classic tag can't have simple tag as parent .
3. Design
pattern - in design pattern in given scenario sometime multiple design pattern are applicable , those type of qs always made me confused .
So , I tried to clear all my doubts thru Javaranch and other notes in resource section .
