Many approaches to object oriented modeling tend not to scale well when the applications grow in size and complexity. Context Mapping technique can be used to manage the complexity in large software development projects. In this article, author Alberto Brandolini discusses the many sides of bounded contexts and how to use them to build a context map to support key decisions in a software project.

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.

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.
