In a short answer - none of them are outdated so you can read them all :)

I used to find the &quot;core J2ee patterns&quot; useful because it covers the whole picture of a web application. (see here: <a href="http://java.sun.com/blueprints/corej2eepatterns/Patterns/index.html" rel="ugc">http://java.sun.com/blueprints/corej2eepatterns/Patterns/index.html</a>&nbsp;)<br />
<br />
However, these patterns were designed in 2002 (or earlier). So I am a bit reluctant to read them now as I do not want to get stuck in old technologies. (I want to move on to JSF and AJAX)<br />
<br />
Out of the 15 patterns described there, which ones do you think are still useful? which ones are outdated or not useful for JSF/AJAX?<br />
<br />
Intercepting Filters<br />
Front Controller<br />
Composite View<br />
View Helper<br />
Dispatcher View<br />
Service To worker<br />
Business Delegate<br />
Session Facade<br />
Service Locator<br />
Transfer object assembler<br />
Value list handler<br />
Composite entity<br />
Transfer object<br />
Service activator<br />
DAO

Java EE-Core J2EE Patterns

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.

Web Applications

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.
