Emphasis of J2ME is shifting to the server


The substance of this book bodes well for the future of J2ME. As you may known, there have been several books on J2ME published in the last year. Like "Java Development on PDAs" by Wilding-McBride. For the most part, these have been aimed at someone completely new to J2ME development. They have tended to focus on the client side, because this is more tangible and easier to explain.
Here Yuan shifts the focus to the server side. He does have screen shots of some client UIs and related code. But the bulk of the discussion moves to server related issues, like how can you sync to a database, or how to send SMS messages in a network. You can consider the book to be focused on connectivity. Not at the lowest level of network connections, but at a higher conceptual level of hooking to existing applications.
In part, this is because UI capabilities are much more limited compared to those on a full Java desktop or even a laptop. But it is mostly because the bigger value is in building logic on the server.
Sound familiar? Mainstream java traced this route from applet development in 1996 to, a few years later, J2EE/XML on the server, when people realised that is where java is best suited. In about half the time, J2ME is walking down the same path. Yuan does not suggest this, but the impression I got from the book is that in a few more years, if J2ME is running on a server that is not as resource constained as its clients, then it may be replaced by J2EE. It seems that if server side J2ME is to prosper, it may be only on very physically limited servers.

NEVER GET TIRED OF READING THIS BOOK OVER AND OVER.


One of the best books that explain the Signal Integrity concept for the High Speed Digital Circuit. I enjoyed reading all of the chapters of this book. By the end of each section, the authors summarized the important concept of each chapter in a little section called "POINTS TO REMEMBER", I found it very useful.

Indispensible Reference Book for Hardcore XSL Programmers


1. This is really a reference, not a tutorial. It does include a "no nonsense tutorial" which will guide you through the basic XSLT topics, but if you have no XML experience, start with one of the more basic Wrox offerings. (David Hunter's Beginning XML -- which I hear will be excellent -- is going to be released by Wrox early in June.)
2. If you are unclear on the purposes of XSLT, understand that it is a programming language for converting data, performing scripting tasks, etc. on the way to a pure HTML or XML layout. I only mention this because some developers seem to be operating under the mistaken belief that XSLT is an appropriate subject for graphic designers, perhaps because XSLT contains the word "style." Do NOT get this book for your design staff.
3. Not a major hurdle for most of us, but some implementations, such as Xalan, are not covered.
That aside, this is a fantastic book. Everything I can think of in the XSL arena is covered, including extending XSL. The author, Michael Kay, who was such a force on the Professional XML team, once again proves to be an excellent writer. The browser specific details are just what I needed to solve many of my real-world production problems. And I continue to be amazed at the speed with which Wrox gets these comprehensive volumes to press.

Great intro to XML-RPC


As with all O'Reilly books there's a great intro to the technologies. They take you through how it works, not just how to deploy some code. When you get to the XML-RPC modules, they don't force a solution on you, but give a great tour of what's available and let you pick. For me, the highlight was the intro to Randy J. Ray's RPC::XML modules (he's also one of the authors). I've been fighting with getting the 'system.*' handlers hacked in with other aproaches and it was great to see someone had already figured out such a clean approach. (Which is something since Perl can get reeeaaal ugly!) This book has saved me many days of wasted development.
