jcommons.org
Common Java extensions. Extends Apache Commons if possible. Open source.
Modules
Helpers for everyday issues.
You jump into a project and have the feeling that you have to code basic things you have done thousands of times?
jcommons.org is a collection of libraries that came into existence because I was too tired to code the same stuff again and again.
The classes and methods have been used in various real-life projects, for various customers, for many years. These are little helpers, no framework, and some will be deprecated once they are available in other libraries.
jcommons.import
Data Importer. Demo. Builds on jcommons.io. Supposed to populate test databases or load external data.
