Deploy Process war file
To deploy a process you must first have a Bonita server. This is usually done using the Tomcat + Bonita bundle or the Docker Bonita image (which itself contains a Tomcat + Bonita bundle). The Tomcat + Bonita bundle will contain Bonita's web application (i.e. war file) which includes the Bonita Web Portal and Engine.
Then for the deployment of a process you need to generate a .bar file from the Studio ("Server" menu). It is this .bar file that will have to be deployed on the Bonita server. To do this you must log in with an account with the administrator profile and in the "Administrator" view, in the "BPM" menu choose "Process" and use the button to add a process that will select the .bar file.
So you do not have to deploy a .war file to deploy a Bonita process (note: this type of deployment existed in the version of Bonita but it is no longer supported).
