Maven project using flowable api, but against a tomcat installation

Hello everyone, I am in need of expanding some functionalities of flowable and for that I need to be able to create a maven project, where I use the flowable api but instead of starting an standalone process engine I would need to connect it to the tomcat server where an installation of flowable is already running.
Viewing the documentation explains how to start a process engine but not how to connect to a running instance (or at least I did not find it)

, is it possible ?, or do I just need to access the same database schema?

Specifically I want to use the Instance and Task Query Service to search only those started by a specific user group. I can’t do this with the rest api, mainly because I can’t send a list of initiators as a parameter (like “startUserIdIn”) of


  • I normally use the api rest, but in this case it does not meet what I need (specific queries to the started process instances)
  • The architecture I have is a tomcat server where a complete installation of Flowable 6.1.2 runs on a postgress database.

any advice will be appreciated!

Thank you very much in advance!

Flowable provides a set of Spring Boot starters to help you embed the different engines (i.e., BPMN, DMN and CMMN) and to expose their RESTful APIs.

See: Flowable OAuth2 Resource Server

The Flowable Spring Boot starters take advantage of Spring Boot’s support for externalised configuration:



# Logging

# Spring Security OAuth2 Resource Server

# Spring Data REST /api

# Spring JPA
# spring.jpa.hibernate.ddl-auto=create-drop
# spring.jpa.hibernate.ddl-auto=update
