Bonita Studio

Discover what Bonita Studio is, as well as its main features.

What Bonita Studio is

Bonita Studio is the central tool to design processes, data models and applications.
It is suited for both citizen developers (business analysts, project managers, power users) and application developers, with back-end java developers working in Bonita Studio and collaborating with front-end developers working in the UI Designer.

Bonita Studio contains a Bonita Runtime (Tomcat, UI Designer, Bonita Portal, Bonita Engine, and an H2 database), suitable for testing an application that is in development.
When you run a process, it is automatically deployed onto the development platform.

Bonita Studio is not intended for any use other than development. As a consequence, the Bonita stack embedded into the Bonita Studio can not be used for production purposes.

Solution:
First, ensure that a valid Java version is available. You can for exemple type java -version on a terminal, and informations about the main Java version used will be displayed.
If you need another version:

  1. Remove the installed Java versions

  2. Download the last stable build of the required Java version on the Oracle website
