z2-Environment

Reference V29-Reference | Download | Subprojects: z2-addons | z2-base | z2-samples | z2-core | org.z2env

The z2-Environment is an open source infrastructure to develop, configure, and run modular, standards-based Java applications without build infrastructure nor deployment procedures and so reduces development operations costs significantly.

During development and maintenance you do not need to have a local build environment installed that complements your source code.

The z2-Environment rebuilds Java sources as required and selectively from your development workspace leading to fast development roundtrips and consistent deployments, and ultimately to minimized integration pains.

The Z2 component model makes developing modular Java solutions easy, comprehensible, and manageable. Z2 shines when used to develop, run, and maintain complex front end and back end solutions.

An an application server environment, Z2 integrates perfectly with Spring, Hibernate/JPA, Vaadin, and much more.

Z2 is used in several large software systems, hosting highly modularized code bases of 600000 lines of code and rising.

This Wiki contains answers to all kinds of practical questions on using Z2.

Versions

Z2 has the following Java Version requirements

Z2 Version Min. Java version required Max Java version supported Max language level
2.1 - 2.3.1 Java 6 Java 7 Java 7
2.4 - 2.5 Java 8 Java 8 Java 8
2.6 Java 9 Java 11 Java 10

Note: Most samples suggest to use the master branch. You may choose another version branch (please check the respective repository).
Make sure you have a corresponding Java Development Kit (JDK) or Java Runtime Environment (JRE) installed. If in doubt, go to Download Java SE.

Note: Running v2.1-v2.3.1 on Java 8 is supported by specifying

com.zfabrik.java.level=7

(or 6, if that is your desired compilation language level) in <home>/run/bin/runtime.properties. By this the Java compiler version detection does not fall back to a lower level.

The latest release is Version 2.9.

Getting started

If you want to get a real quick understanding of what Z2 is and how to give it a try start here:

Projects

This site is split into sub projects:

  • z2-base: The base components of z2.
  • z2-core: The z2 kernel included with z2 base with sources
  • z2-addons: Add-ons that complement z2-base with additional features
  • z2-samples: Home of the samples listed below.

And then there is...

Samples

There are various samples available that highlight specific use-cases and may serve as a solution template, when you just cannot get it to work or do not know where to start.

Howtos

Howtos provide practical information on various aspects that you may run into when looking deeper.

Add-ons

The z2 base distribution is really just the most basic but still practically useful set of z2 modules. Addon repositories provide additional modules that add complete feature sets. Addons are versioned along with z2 base and may be included by simply adding component repositories.

When productising your solution, you will want to isolate yourself from intermediate changes outside of your control. See also How to create your own system for more information how Z2 accomplishes that with pure version control tool use.
