In anticipation of the 2.0 release for JBoss AOP, Flavia Rainone has posted a two-part tutorial on a new feature of the 2.0 release, typed advices. This tutorial assumes familiarity with aspect oriented programming and JBoss AOP. The latest version of JBoss AOP is 2.0.0.CR4 (links to download are available at the bottom of the JBoss AOP project pages.)
Typed Advices Tutorial - Part 1
As we get closer and closer to our 2.0.0.GA release, I found it would be interesting to post a tutorial on typed advices, one of the new features of the next GA release.
The tutorial, targeted to users already familiar with the basics of JBoss AOP, will be split into parts. The plan is to post a new part every Monday. Enjoy!

This HOWTO is for testing purposes only. The RHEL4 Xen paravirtualized kernels are ready, but there is no installer support yet. This temporary HOWTO describes how to turn a fully virtualized RHEL4 guest into a paravirt Xen guest. Proper installation of RHEL4 guests will be available in Anaconda sometime around the end of April 2007. |

JBoss Seam is a next generation web application framework developed by JBoss, a division of Red Hat. It leverages years of hard work and experience gathered from both the open source community and the Java EE community. The goal of Seam is to make web applications easier to develop, easier to test, better performing, and more scalable. Seam provides built-in support for important web application features that are rarely supported in other frameworks, such as isolated workspaces, business process integration, rules integration, AJAX, and others.
