Big thanks to Bryan, Kathy, and Bert for an outstanding book. My goal was to score above 90% and I HF Servlets & JSP was a huge help.
For those interested let me testify
I had spent three weeks studying for the WCD1.3 exam when I found copy of the book after which I decided on 1.4 certification. I studied the HF book exclusively for a week, took the mock exam (got 46 out 69 correct), then studied the three specs: Servlet2.4, JSP2.0 and JSTL1.1 for two days prior to taking the exam. I also took the free mock exams at JDiscuss
never making more than 85%. Of course, I also spent alot of time playing with Tomcat 5, "Hey, I wonder what would happen if I did this.."
One thing I thought was very considerate of the HF authors was the annotated mock exam answers complete with cross-references to the specs. nice..
Good luck to everyone preparing.. Study hard, you can do it
