I'll list the pros and cons from my perspective:
PROS: 1. Very short - Sometimes size does matter. In this case, there was no over-extensive analyzations of the code. Only key portions.
2. Covered some of the essentials of JSP programming. JDBC, Connection pooling, XML, Servlet integration, JavaMail. As short as this book was, it still did a nice job giving examples of the usage which is what most books do anyways.
3. Covers basic tags used in JSP and also usage of JavaBeans.
Cons:
1. Did anybody else notice that the cover says it covers ASP, HTML, and Servlets? (NOTE: ASP?????)
2. No mention of Tag Libs which are a big part of JSP. It does require a lot of detail but at least a small taste of it would be nice.
3. It would have been nicer if the author moved the setting up of the Tomcat server section to the beginning so that the examples could be tried as you went.
Other than the above mentioned items, this is definitley a good book to purchase. The price is kinda hefty but it does provide a nice overview of the JSP technology and the basics of what you would need to know.
Like a reader mentioned before, pretty much, this book covers all that you will need to know for JSP.
I have already worked with JSP so I was able to fly through the book in 2 hours without typing all of the examples. Just thought I'd throw that out there just in case anyone was wondering on how much time it would consume.
