Trying to combine JSF and JSP is like trying to shoehorn a foot into a glove: it's possible, but it's really just a stopgap measure until something better comes along. In this article, JSF enthusiast Rick Hightower introduces you to what he likes best about Facelets: easy HTML-style templating and reusable composition components.
Where possible, creating Web applications — including Ajax-based applications — in a RESTful way avoids a large class of bugs. However, a pitfall of REST (REpresentational State Transfer) is sending duplicate data across similar XMLHttpRequests. This tip shows how the moderate use of session cookies can maintain just enough server-side state to significantly reduce client-server traffic, while still allowing fallback to cookie-free operation.
Exploratory visualization based on multiple coordinated views. Improvise has been used to explore election results, particle trajectories, network loads, music collections, the chemical elements, and even the dynamic coordination structure of its own vis

Willkommen in der iteraplan Community. iteraplan ist das erste Open Source Enterprise Architecture Management (EAM) Werkzeug für das strategische Management Ihrer Applikationslandschaft. Das Software- und Beratungshaus iteratec hat das Werkzeug iteraplan erstellt und übernimmt auch zukünftig die Führung in der Weiterentwicklung von iteraplan im Rahmen der Open Source Community.
The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming.
In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems.
The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own.
The book covers the classical problems, including "Readers-writers", "Producer-consumer", and "Dining Philosophers". In addition, it collects a number of not-so-classical problems, some written by the author and some by other teachers and textbook writers. Readers are invited to create and submit new problems.
In what I hope will be the first of several articles about Guice, a new lightweight dependency injection container from Bob Lee and Kevin Bourillion from Google, this article examines the simplest and most obvious use case for the Guice container, for mocking or faking objects in unit tests. In future articles I will examine other, more ambitious areas where it can be used, including dependency elimination in large code bases.
Problem:
Easily integrating your Linux host into a Windows environment ...
Solution:
This solution allows one to very easily navigate any number of windows/samba servers and shares with any file management application (and from the shell).
Teaser for an interesting book...
EAI - The Broader Perspective
No one should have (or will) ever dared to build a 'Single System' which will take care of the entire business requirements of an enterprise. Instead, we build few (or many) systems,and each of them takes care of a set of functionalities in a single Line of Business (LOB). There is absolutely nothing wrong here, but the need of the hour is that these systems have to exchange information and interoperate in many new ways which have not been foreseen earlier. Business grows, enterprise boundaries expands and mergers and acquisition are all norms of the day. If IT cannot scale up with these volatile environments, the failure is not far.
ven though Web 2.0 and rich Internet applications (RIAs) are all the rage these days, building a rich Web front end for your stakeholders is not the answer when thick-client functionality is what you really need. I stated as much in my previous article, "Building a Java App Server Foundation for Thick-Client Deployment," which showed how to leverage a traditional Java Web server architecture to easily deploy thick clients.
Exception Handling with Spring and Log4J
How to log exceptions. This technique will log messages to your server log file, send an email, with the tag stack of the error, for error level warnings and display a generic page to the user.
First step is to set up Log4j.
Make sure you have the following classes in application lib or common server lib.
activation.jar
This can be got from http://java.sun.com/products/javabeans/jaf/downloads/index.html
Set up your log4J configuration file, put this file in your WEB-INF directory
