Across is a Java framework that aims to facilitate module based development for Java (web) applications. It builds heavily on Spring framework and allows defining a module consisting of a number of classes and configuration files. Every module defines its own Spring application context and can share one or more beans with other modules.

There is a newer version: 6.0.0
