RS Libs

A Java class library that is useful for day-2-day development


The RS Library project was established to support my daily Java development. It is a collection of interfaces, classes and static Utils that are part of each of my projects. That’s why I decided to publish them the same way so everyone can benefit of the work. And of course, it will be easier for myself to fulfill common development tasks.

RS Library is currently divided into two areas, each of them published as a Maven module to RS Library:

  • Base Library – provides non-specific code such as Java language tasks, IO tasks, bean handling, Configuration helpers and many more.
  • Templating – provides an easy Typo3-like way of processing text templates within Java.

Most of this code was created when I faced specific problems in my professional work. I usually work out solutions in private projects, test them there and then apply them to my professional work. That’s why few of my employers will find the same code in their products. However, the code was created outside of professional environments and therefore is my own intellectual property.

RS Library modules are maintained in the same Maven project and, hence, follow the same release cycle. That means that each modules will have the same version numbers and are published at the same time.

Latest Version

Latest version is 3.0.0.

Upgrading v2 to v3

V3 is a major release that removes the Data APIs. They will not be maintained any longer - in favour of Spring Data Framework. Do not upgrade to this version when you need the Data API.

Upgrading v1 to v2

V2 which has some minor compatibility breaks that result from upgrading commons-configuration dependency:

  • Replace references to org.apache.commons.configuration.Configuration by org.apache.commons.configuration2.Configuration
  • SubnodeConfiguration was removed in favour of HierarchicalConfiguration
  • New utility methods for the ease of creating configurations from properties and XML files were added in ConfigurationUtils:
    • getXmlConfiguration() - will create a XMLConfiguration object from a given file or URL
    • getPropertiesConfiguration() - will create a PropertiesConfiguration object from a given file or URL
