Project structure
This page defines the elements used to compose a Bonita project.
Bonita project elements
Bonita projects are based on processes but also data, user interfaces, identity management and extensions.
|
Using all the concepts in a project allows to take the full advantage of the Bonita platform. However, it is not required to use all the concepts to create a valid Bonita project. |

Extensions
Bonita project can be extended by creating custom components. These are called extensions.
Some extensions are used to add elements to those provided while others are used to enforce the Bonita platform possibilities.
Extensions can be developed outside the Studio with your favorite IDE.
| Extension | When to use | Tool |
|---|---|---|
When the provided connector do not cover your requirements |

When the provided actor filter do not cover your requirements |

Bonita provided application |

Available in the extensions Marketplace |
Other dependencies
In addition to the above extensions, it is possible to add any kind of third party dependencies in the classpath of the project.
Those dependencies can be added to processes classpath. They are also added in the parent application classpath.[1] It is recommended to use them to add specific extension such as Event handlers, Platform commands, custom Web Servlets or Filters. Since 2023.2, servlets annotations are scanned at startup when found in the classpath.
Bonita Project Composition
Extensions are re-usable elements, they can be shared between projects. Extensions are added to Bonita projects as Maven dependencies.
In the Studio, extensions are managed in a dedicated view.
|
Even if it is possible to manually import extensions in Bonita Studio, it is highly recommended to publish your extensions on public or private maven repositories. Here is an example on how to deploy an extension on GitHub packages. |
