Introduction

AppJars is a suite of full-stack functional modules for Java enterprise applications. Each module — an "AppJar" — delivers a complete, production-ready capability that is added to an application as a dependency, instead of being built and maintained from scratch.

The idea is straightforward: every enterprise application ends up needing the same foundations and the same plumbing, and that work gets rewritten project after project. AppJars package the analysis, design, implementation, testing, and ongoing maintenance of those recurring needs, so that development effort can be concentrated on what actually makes each application unique.

The problem AppJars solve

Modern enterprise applications share a common infrastructure layer that rarely differentiates the product, yet consistently consumes a large share of the effort — both to build initially and to maintain over time. Re-implementing that layer for every new application is slow, repetitive, and costly.

AppJars address this layer as a set of composable building blocks. Each one can be adopted independently and incrementally: start with what is needed today, and add more as requirements grow.

What AppJars offer

• Production-ready — each module is a complete, tested feature, not a starting template.
• Composable — modules are adopted independently and do not depend on one another.
• Pluggable — integration is designed to require minimal configuration.
• Extensible — every layer exposes extension points, so behaviour can be adapted to each application.

There is more to come. Stay tuned.
