In this interview conducted at the SpringOne 2GX conference, Rod Johnson talks about the new advancements SpringSource is bringing to the enterprise Java space, including new cloud options. Johnson discusses open-source Java in general, including the flap over the direction of OpenJDK and Apache Harmony. And he delves into the new Code2Cloud effort from SpringSource and Tasktop, and much more.
Ivar Jacobson, one of the founders of UML, RUP, use cases, introduces his vision for a next generation development methodology that is both agile yet large like UP, by having humans collaborate with 'Intelligent Agents'. Ivar also talks about his views on UML, MDA, AOP, and the future. Recorded at JAOO (jaoo.dk).
SpringSource CTO and AspectJ project lead Adrian Colyer discusses where Aspect-Oriented Programming (AOP) should be used, practical applications of AOP in enterprise situations such as Hibernate exception translation and automatic operation retry on nonfatal exceptions, and AOP mechanisms in Spring 2.5.
JBoss has released Byteman 2.0.0, an open source Java bytecode manipulation tool licensed under GNU LGPL 2.1. Byteman is a Java agent which helps testing, tracing, and monitoring code. It allows developers to change the operation of Java applications, either as it is loaded or during runtime.
A new version of the Spring.NET framework, version 1.3, was recently released. InfoQ spoke with Mark Pollack, founder and lead of the Spring.NET project, to learn more about this release and what new capabilities it brings, and also to learn more about the new Spring Integration.NET project.
Guice, a lightweight Java dependency injection framework created by Google, recently released version 2.0. InfoQ spoke with Google Developer Team member Jesse Wilson to learn more about this release and what capabilities it adds to Guice.
Spring AOP/AspectJ combination offers many choices, whether they are AOP system, syntax or weaving related options, and a clear understanding of all those choices is important to apply them pragmatically when using Aspects in enterprise applications. Ramnivas Laddad said just one kind of AOP won't fit all applications and choosing the right combination will help developers be successful with AOP.
While many think of Aspects for cross-cutting concerns such as transaction management, persistence and role based security, another key value for them has been as an enabler for Annotations for ordinary projects. Using Aspects as a way to implement annotation handlers is a different way to think of them than as the traditional architect's "cross cutting concerns" view.
Custom annotations are a great way to add common reusable behavior to Java applications. John Heintz from New Aspects discussed at the recent No Fluff Just Stuff (NFJS) Java Symposium, the design techniques for adding behavior to Java Annotations.
