Eclipse Integration and Custom Code.

The Mendix rapid application development platform can be extended by custom code written in Java and JavaScript. Even though for most applications the standard functionality is more than sufficient, custom code enables you to fall back on a general purpose language in the case that you need extensions.


  • Use Java to write highly specific code for your application
  • Tap into the vast ecosystem of existing Java frameworks
  • Add features you need without having to wait for a new Mendix release

Technical Features

  • Proxies for entities of your domain model are generated by the Business Modeler
  • Custom code can communicate with the Mendix Business Server through an application programming interface (API)
  • Add your own library files (.jar) to extend the functionality of the server
