Painlessly Migrating to Java Jigsaw Modules - a Case Study
This article is a case study of changes required in an application to make use of the new Java Platform Module System. An understanding of the module system will become an important skill for Java developers, using Java 9 and beyond.

Java 9, OSGi and the Future of Modularity (Part 2)
The flagship feature of Java 9 will be the new Java Platform Module System (JPMS). Given the maturity of OSGi there were technical, political and commercial reasons why another Java module system will soon exist. In this article we compare the two from a technical perspective and see how JPMS and OSGi can work together.

Programming with Modularity and Project Jigsaw. A Tutorial Using the Latest Early Access Build
Project Jigsaw is the hallmark feature of Java 9, the next major version release of Java, and is destined to bring modular programming into the Java mainstream. After years of negotiating and myriad JSRs and JEPs, Jigsaw is starting to take its final form. This tutorial considers all aspects of programming and migration to Project Jigsaw.

Project Jigsaw is Really Coming in Java 9
Eight years in the making, Project Jigsaw is finally coming to Java 9. With the potential to introduce breaking changes to your code, modularization will certainly change the way we think about our projects and the JDK itself. In this article, Nicolai Parlog tells us what we need to know and what we need to do to prepare

Book Review and Interview: Mastering Eclipse Plug-in Development
Regular InfoQ Java contributor Dr. Alex Blewitt has recently published a follow-up to last year’s "Eclipse 4 Plug-in Development by Example”. Called “Mastering Eclipse Plug-in Development,” the book, like its predecessor, is essentially a tutorial, but it assumes that you are already familiar with the basics of building plug-ins for the Eclipse IDE, and rapidly dives into advanced topics.

Peter Kriens Returns to OSGi Alliance
Peter Kriens, one of the driving forces behind OSGi, announced his return to the OSGi Alliance, where he served as director for 11 years until early 2012. InfoQ caught up with Peter to discuss his return, OSGi, and his latest project jpm4j.

Book Review: Java Application Architecture
Java Application Architecture: Modularity Patterns with Examples using OSGi is Kirk Knoernschild's seminal book on a pattern catalogue for modular systems design. Starting with an overview of the arguments for modularity, the main section in the book introduces eighteen categorised patterns for module development, and concludes with an OSGi example. InfoQ spoke to Kirk to find out more about it.

Interview With Ross Mason On The Release Of Mule 3
Mulesoft recently released Mule 3, their next generation ESB platform. The product comes with a lot of architectural changes under the hood to support the features aimed at making the product easier to use, such as Mule Cloud Connect and Flow, a message flow based service design. InfoQ caught up with Ross Mason to learn more about the product release and the new features in the product offering.

Modular Java: Declarative Modularity
The fourth of the Modular Java series covers declarative modularity. It describes how components can be declaratively defined and wired together, without having a code dependency on OSGi APIs. Declarative services will be used to write POJOs together dynamically, such that code no longer needs to explicitly register or consume OSGi services, and without any start ordering dependencies.

Classloader Acrobatics: Code Generation with OSGi
Porting great infrastructure to OSGi often means solving complex classloading problems. This article is dedicated to the frameworks that face the hardest issues in this area: those that do dynamic code generation. Incidentally these are also the coolest frameworks: AOP wrappers, ORM mappers, and service proxy generators are just a few examples.

Modular Java: Dynamic Modularity
Modularity is an important aspect of large Java systems. Build scripts and projects are often split up into modules in order to improve the build, but this is rarely taken into account at runtime. This third part of the Modular Java series discusses dynamic modularity, how a bundle's classes are resolved, how they can come and go, and how they can communicate with each other.
