Reasonably good By kalyson I got this book partially because I prefer more of a textbook format than the Head First books. However, I have found a lot of errors, inconsistencies and confusing explanations in this book. Some of the errors are minor, but others really cause fundamental confusion. That being said, there is a lot of very good information in this book and some of the explanations and examples are pretty good.

Rod Hilton 's rants about software development, technology, and sometimes Star Wars. This exam was very interesting for me. I decided after I completed my Sun Certified Java Programmer certification that the next one I wanted to tackle was the web cert. Generally when I learn something new, I learn by example and experimentation. Only by studying the material and practicing for the exam did I come to see the many gaps in my knowledge. The process both alerted me to the existence of the gaps, as well as filled them in.
The SCJP exam was very valuable for me. Not just because it makes my resume looks nice, or because Sun sent me a snazzy lapel pin, but because the process involved in preparing for the exam made me a far, far greater Java developer. I found, unfortunately, that the book did not make me feel like I was coming to a complete and thorough understanding of the material. I understood what I read, but I still felt like I had gaping holes.
I decided that I needed a book that gave me excersizes. Learning means doing, rather than merely reading. Oh, yeah it will. Both of these books had problems for me. The Head First book was good for something nebulous and conceptual such as Design Patterns, but it was awful at teaching me something as formal as J2EE Specifications ultimately what the tests are on.
The Bridgewater book was much better in this regard, but it suffered from one problem that was unforgivable: typos. The book was riddled with typographical errors. For example, there was a section that had a few code snippets showing how to provide run time expressions as values for attributes in tags. The snippets showed using the expressions without surrounding quotes. There were two in a row, and it was in the section introducing using run-time expressions for values.
It seemed wrong, though, so I checked it out and discovered that they DO need the quotes. Had I not checked, I would have had incorrect beliefs about the topic. Another example was far more confusing. When writing classic custom tags, doStartTag has to return a constant indicating to the web container what to do with the body.
Using it would prevent compilation from succeeding. One of these mock exams was actually in the Bridgewater book. These kinds of typos were peppered throughout every chapter, some of them extremely misleading and others less damaging.
I had to do a great deal of work to fix some false conclusions I came to as a result of these typos. Yet it was still the best book I used to learn the material. In the end, I wound up studying almost exclusively from the Bridgewater book, then filling in a few gaps with the Head First book. I feel very confident writing Servlets and JSPs, and I feel like I have a very thorough and complete understanding of that copic.

Answer 1: I've never seen much value in certification, to be honest. The only thing I can see it doing is giving your CV a better chance of getting past an HR department which can't understand the rest of what you're telling them. On the side of someone hiring, I wouldn't put any store in it, basically. I suspect I can get a much better idea of whether someone's likely to be any good or not based on a 10 minute phone screen than based on their certs.
